The Lichen Genus Parmotrema in South Korea
1Abstract
Parmotrema A. Massal. is a common lichen genus scattered throughout the Korean Peninsula; however, no detailed taxonomic or revisionary study of this genus has been conducted for nearly two decades. Therefore, this study revised the taxonomy of this genus based on specimens deposited in the lichen herbarium at the Korean Lichen Research Institute and samples wereidentified using recent literature. In this revisionary study, a total of eighteen species of Parmotrema including eight new records [Parmotrema cetratum (Ach.) Hale, Parmotrema cristiferum (Taylor) Hale, Parmotrema grayanum (Hue) Hale, Parmotrema defectum (Hale) Hale, Parmotrema dilatatum (Vain.) Hale, Parmotrema margaritatum (Hue) Hale, Parmotrema pseudocrinitum (Abbayes) Hale, and Parmotrema subsumptum (Nyl.) Hale] are documented. Detailed descriptions of each species with their morphological, anatomical and chemical characteristics are also given and a key to the known Parmotrema species of the Korean Peninsula is presented.
Parmotrema A. Massal. (previously known as Parmelia s. lat.) is one of the largest genera of parmelioid core in the family Parmeliaceae [1]. According to Bayesian analysis of nuclear internal transcribed spacer (ITS), large-subunit rDNA and mitochondrial small subunit (SSU) rDNA sequences carried out by Blanco et al. [1], the parmotremoid genera Rimelia, Canomaculina, and Concamerella are synonymized with Parmotrema. These findings were further confirmed by morphological analysis of the same groups by Louwhoff and Crisp [2]. Molecular phylogenetic analyses carried out by Divakar et al. [3] revealed that P. reticulatum and P. clavuliferum formed a monophyletic clade based on nuclear ITS rDNA and mitochondrial SSU rDNA sequences. Thus, P. reticulatum and P. clavuliferum were combined under the older name, P. reticulatum.
The genus Parmotrema is usually characterized by large foliose thalli with broad lobes, commonly with a broad erhizinate marginal zone on the lower surface, pored epicortex, thick-walled hyaline ellipsoid ascospores, sublageniform or filiform conidia and with or without marginal cilia. The greatest distribution of the genus is in tropical regions, where more than 220 species are known [4]. Currently, this genus is composed of c. 350 species worldwide [1, 5, 6]. To date, only 12 species have been reported from South Korea: Parmotrema arnoldii (Du Rietz) Hale 1974, Parmotrema austrosinense (Zahlbr.) Hale 1974, Parmotrema clavuliferum (Räsänen) Streimann 1986 [previously known as Rimelia clavulifera (Räsänen) Kurok. 1991], Parmotrema crinitum (Ach.) M. Choisy 1974, Parmotrema eciliatum (Nyl.) Hale 1974, Parmotrema mellissii (C. W. Dodge) Hale 1974, Parmotrema perlatum (Huds.) M. Choisy 1952 (previously known as Parmotrema chinense sensu auct.), Parmotrema praesorediosum (Nyl.) Hale 1974, Parmotrema reticulatum (Taylor) M. Choisy 1952 [previously known as Rimelia reticulata (Taylor) Hale & A. Fletcher, 1990], Parmotrema subtinctorium (Zahlbr.) Hale 1974 [previously known as Canomaculina subtinctoria (Zahlbr.) Elix 1997], Parmotrema tinctorum (Despr. ex Nyl.) Hale 1974 and Parmotrema ultralucens (Krog) Hale 1974 [7].
The current study resulted eight species, Parmotrema cetratum (Ach.) Hale 1974, Parmotrema grayanum (Hue) Hale 1974, Parmotrema defectum (Hale) Hale 1974, Parmotrema dilatatum (Vain.) Hale 1974, Parmotrema margaritatum (Hue) Hale 1974, Parmotrema pseudocrinitum (Abbayes) Hale 1974, and Parmotrema subsumptum (Nyl.) Hale 1977 as new records from South Korea. Further, Parmotrema cristiferum (Taylor) Hale 1974, which was identified incorrectly as Parmotrema ultralucens (Krog) Hale 1974 [8], also is added as a new record. Thus, a total of 18 species of Parmotrema are reported from South Korea. The first world monograph of Parmotrema was published under the name Parmelia subgenus Amphigymnia by Hale in 1965 [9]. Later, monographic studies of the genus Parmotrema were carried out by Krog and Swinscow [10], Elix [11, 12], and Divakar and Upreti [13].
MATERIALS AND METHODS
The study was based on specimens deposited in Korean Lichen Research Institute (KoLRI). The lichen samples were identified using stereo and light microscopes. Specifically, a dissecting microscope (SMZ645; Nikon, Tokyo, Japan) was used to identify morphological characteristics of the thallus and the reproductive structures, while a compound microscope (Zeiss Scope. A1; Carl Zeiss, Jena, Germany) was used to study the anatomy of thalli and fruiting bodies. Spot test reactions were carried out on thalli under the compound microscope. Thin layer chromatography (TLC) was performed in solvent system A (toluene:dioxin: acetic acid = 180:45:5) [14]. All examined localities of specimens were mapped using the open source GIS software Quantum GIS 1.7.0 (QGIS). Voucher specimens have been deposited in the herbarium of the Lichen and Allied Bio-resource Center at the KoLRI, Sunchon National University, South Korea. In the identification key, the newly reported species are indicated in bold.

Remarks
P. austrosinensis has a thallus rather soft to the touch with eciliate, marginal soralia, and C+ red medulla. According to Divakar and Upreti [13], this species resembles P. sancti-angelii and P. hababianum in its sorediate condition. However, P. sancti-angelii is different from P. austrosinensis in that it has a coriaceous, ciliate, granular sorediate thallus with gyrophoric acid in the medulla. P. hababianum, which has a soft thallus, differs from P. austrosinensis in having cilia along the margins and C-medulla. P. cooperi also resembles P. austrosinensis, but it has ciliate lobe margins [12].
Ecology and distribution
In South Korea, this species is found on the bark of Pinus sp. and Cherry trees in Mt. Halla, Mt. Illim, Mt. Ungseokbong, Baeal Beach, Gwangpo Village and the Wondangbong area. This is a pantropical species that has been identified in tropical regions of Africa [9]. It has also been recorded from Asia, America and Central American regions.

Thallus foliose, loosely attached to the substratum, coriaceous, 4~6 cm broad, lobes rotund, 5~10 mm wide; margins entire, crenate, eciliate. Upper surface pale grey, dull, emaculate, without isidia, sorediate. Soralia marginal to submarginal, sinuous and revolute. Medulla white. Lower surface black, smooth with broad, pale brown to tan, erhizinate marginal zone. Rhizines, sparse, simple, short, up to 1 mm long. Apothecia and pycnidia not seen in the specimens examined (Fig. 1A~1E).
Chemistry
Cortex K+ (yellow), C-, KC-, P-; medulla K+ (red), C-, KC-, P+ (orange-red). TLC: atranorin, chloroatranorin, salazinic acid and unknown (Fig. 2).
Remarks
This is the first record of this species in South Korea. P. cristiferum is characterized by the loosely adnate, coriaceous thallus, eciliate lobes, marginal soralia and salazinic acid in the medulla. According to Divakar and Upreti [13], this species is closely related to P. stuppeum in having marginal soralia and the presence of salazinic acid, but it differs in that it has ciliate margins.
During the current study, the specimens referred to under Parmotrema ultralucens (Krog) Hale [8] were identified as Parmotrema cristiferum.
Ecology and distribution
In South Korea this species has only been recorded on a rock from a single location on Mt. Naejang. However, this organism is a cosmopolitan species that is widely distributed in tropical and subtropical areas [10, 12].
Specimens examined
Mt. Naejang, on rock, 35°29'38" N, 126°54'28" E, alt. 590 m, 29 Jun 2003, J. S. Hur, 030473 (Fig. 3).

Thallus foliose, closely attached to the substratum, coriaceous, 5~8 cm broad, Lobes round to irregular, 5~10 mm wide; margins crenate, eciliate. Upper surface pale grey, smooth, somewhat shiny, rugose, cracked in the center, sorediate. Soralia marginal, linear, but not continuous for about 1 cm, sorediate margins revolute. Medulla white. Lower surface minutely wrinkled, black with smooth, pale brown to tan, erhizinate marginal zone. Rhizines, sparse, simple, short, up to 1 mm long. Apothecia and pycnidia not seen in the specimens examined (Fig. 1A~1E).
Chemistry
Cortex K+ (yellow), C-, KC-, P-; medulla K-, C+ (rose to red), KC+ (red), P-. TLC: atranorin, chloroatranorin and lecanoric acid (Fig. 2).
Remarks
This is the first report of P. defectum from South Korea. This species is characterized by a rugose, emaculate, thallus with eciliate margins and lecanoric acid in the medulla. According to Divakar and Upreti [13], P. defectum is a saxicolous species, but this species was found on the bark of Pinus sp.
Ecology and distribution
In South Korea, this species was recorded on a rock and bark from two locations, Bokil-do and from a large bridge in Geumho. Outside of South Korea, this species has been recorded in African and South Asian regions.
Specimens examined
Bokil-do, on bark, 34°09'31.7" N, 126°33'27.7" E, alt. 5 m, 31 Dec 2004, J. S. Hur, 041654; Geumho, Geumho-dong, Gwangyang-si, Jeollanam-do, on rock, 34°56'6.12" N, 127°43'5.71" E, alt. 14 m, 16 Jan 2010, J. S. Hur, M. H. Jeong, GW1012 (Fig. 3).

Parmelia dilatata Vain., Acta Soc. Fauna Flora Fenn. 7: 32 (1890).
Thallus foliose, loosely attached to the substratum, coriaceous, 4~6 cm broad. Lobes rotund, 5~10 mm wide; margins entire, crenate, eciliate. Upper surface pale grey, shiny, emaculate, without isidia, sorediate. Soralia marginal, globular or confluent, soredia granular. Medulla white. Lower surface black, smooth with broad, pale brown to tan, erhizinate marginal zone. Rhizines, sparse, simple, short, up to 1 mm long. Apothecia and pycnidia not seen in the specimens examined (Fig. 1A~1E).
Chemistry
Cortex K+ (yellow), C-, KC-, P-; medulla K-, C-, KC+ (red), P+ (red). TLC: atranorin, chloroatranorin, usnic acid, protocetraric acid and unknown 4 (Fig. 2).
Remarks
P. dilatatum is characterized by coriaceous, eciliate lobes, marginal soralia and protocetraric acid in the medulla. Externally, this species externally resembles P. cristiferum, but it differs due to the presence of protocetraric acid in the medulla [13].
Ecology and distribution
In South Korea, this species has only been recorded on a rock from a single locality of Mt. Chiri. Apart from South Korea, this species has been reported from Asian and Central American regions.
Specimens examined

Parmotrema margaritatum (Hue) Hale, Phytologia 28: 337 (1974)
Parmelia margaritata Hue, Nouv. Arch. Mus. Paris. Ser. 4 1:193 (1899).
Thallus foliose, loosely attached to the substratum, medium sized, 3~6 cm across, rather coriaceous to crisp. Lobes rotund, irregular, 5~8 mm wide, with several ascending, simple to dichotomously branched cilia. Cilia simple, 0.5 to 1 mm long, moderately dense. Upper surface pale grey to grey, smooth, dull, maculate, without isidia, sorediate. Soralia terminal on the lacinules, rounded or confluent and sinuous, sorediate lobes revolute. Medulla white. Lower surface black, with shiny, brown erhizinate marginal zone. Rhizines simple to slightly branched, dense in the central part. Apothecia and pycnidia not seen (Fig. 1F~1J).
Chemistry
Cortex K+ (yellow), C-, KC-, P-; medulla K+ (red), C-, KC-, P+ (orange red). TLC: atranorin, chloroatranorin, salazinic acid (Fig. 2).
Remarks
P. margaritatum shows a close resemblance to P. stuppeum in the presence of marginal cilia, soralia and similar chemical substances, but the presence of secondary lobules and a faint maculate upper surface differentiate it from the latter. P. leucosemothetum also very closely resembles P. margaritatum, but has a highly maculate upper surface and lacks secondary lobules [13].
Ecology and distribution
In South Korea, this species has been recorded from Mt. Kongduck, Mt. Naejang, and the Asan Hwasun area. Outside of South Korea, this species has been reported from India [13], the United States [9], and Venezuela [15].

Parmotrema chinense auct., non (Osbeck) Hale & Ahti, Taxon 35: 133 (1986).
Thallus foliose, membranaceous to coriaceous, loosely attached to the substratum, 5~8 cm broad. Lobes rotund, irregular, 5~8 mm wide; margins entire to crenate, but lacking sublinear lacinae, eciliate. Cilia simple to branched, rather long (0.5~2 mm), moderately dense to dense. Upper surface pale grey to mineral grey, dull, without isidia, sorediate. Soralia marginal to submarginal, causing lobe margins to become revolute and suberect, ultimately appearing labriform, soredia granular. Medulla white. Lower surface black, shiny with a broad 3~6 mm wide, brown to tan erhizinate marginal zone. Rhizines moderately dense, simple, up to 2 mm long. Apothecia and Pycnidia not seen (Fig. 1F~1J).
Chemistry
Cortex K+ (yellow), C-, KC-, P-; medulla K+ (yellow), C-, KC-, P+ (orange-red). TLC: atranorin, chloroatranorin, stictic acid, constictic acid, menegazziaic acid (trace) and norstictic acid (trace) (Fig. 2).
Remarks
P. perlatum is characterized by a loosely attached thallus, marginal to sub marginal soralia with strongly revolute and suberect margins, and the presence of stictic acid in the medulla. The organism resembles Parmotrema reticulatum in the nature of soralia, but the latter species has a maculate, reticulately cracked upper surface and salazinic acid in the medulla. P. perlatum is similar to P. crinitum due to the presence of a brown to tan erhizinate marginal zone and stictic acid complex in the medulla, but the latter species has an isidiate upper surface [13]. According to Park [16], the species description was given under the species name P. chinense (Osbeck) Hale & Ahti.
According to Louwhoff's descriptions [17], P. perlatum is sensitive to air pollution and prefers well-lit, neutral to somewhat acid-barked, broad-leaved trees and siliceous rocks and coastal rocks where illumination is moderate to good. However, the recent revisionary work conducted by Jabłońska et al. [18] stated that P. perlatum is close to extinct from Poland.
Ecology and distribution
In South Korea this species has been recorded from Mt. Ungseok, Mt. Chiri, Mt. Hambeak, Mt. Taebaek, and the Sanchong area. P. perlatum is a cosmopolitan lichen and widespread in both the southern and northern hemisphere and tropical areas [9, 17]. This species has been identified in many European countries [18], as well as other Asian countries including Australia [12], India [13], Japan [19], and Taiwan [4].

Parmotrema chinense (Osbeck) Hale & Ahti, Taxon 35: 133 (1986).
Thallus foliose, loosely attached to the substratum, membranaceous to coriaceous, up to 18 cm across. Lobes rotund to irregular, 5~15 mm wide; margins entire to crenate, eciliate. Upper surface pale grey to grey green, shiny, becoming dull towards the thallus center, somewhat longitudinally folded in the marginal region, emaculate, without soredia, isidiate. Isidia sparse to dense, laminal and eventually marginal, granular to filiform, simple to coralloid branched, thin, brown tipped or concolorous. Medulla white. Lower surface black, minutely wrinkled, smooth, shiny, with a broad, erhizinate, pale brown to dark tan marginal zone. Rhizines sparse, simple, short. Apothecia and pycnidia not seen (Fig. 1K~1N).
Chemistry
Cortex K+ (yellow), C-, KC-, P-; medulla K-, C+ (red), KC+ (red), P- TLC: atranorin, chloroatranorin, lecanoric acid (Fig. 2).
Remarks
P. tinctorum is characterized by a large, loosely adnate thallus with broad, eciliate, laminaly isidiate lobes and lecanoric acid in the medulla. This species is very similar to P. pseudotinctorum, but the latter has inflated isidia. The species that grow under high humidity and moist conditions are larger in size, with large lobes and cylindrical, coralloid isidia, whereas species that grow under dry and stressed conditions are smaller in size with narrow lobes and granular, simple isidia [13].
During the current study, the specimens previously recorded as Parmotrema saccatilobum (Taylor) Hale [21] were identified as Parmotrema tinctorum.
Ecology and distribution
In South Korea, this species has been recorded from Mt. Sonun, Mt. Jogae, Mt. Halla, Mt. Cheontae, Mt. Jakseong, Mt. Nogudwit, and the Daeki Valley area. This is a cosmopolitan species [12] widely distributed throughout tropical, subtropical and temperate regions [13].

Species excluded from this study
According to the literature, lichen species Parmotrema arnoldii (Du Rietz) Hale, Parmotrema crinitum (Ach.) M. Choisy, Parmotrema mellissii (C. W. Dodge) Hale and Parmotrema eciliatum (Nyl.) Hale have been reported from South Korea. However, the specimens of these species could not be traced; therefore, the description is based on previous literature.

Parmotrema subarnoldii (Abbayes) Hale, Phytologia 28: 339 (1974).
P. arnoldii is characterized by the presence of a slightly maculate upper surface, coarsely sorediate margins of the lobes, revolute sorediate tips with irregular eruptions, and atranorin, alectorinic acid, and α-collatolic acid in the medulla [16, 18, 22]. This species is very closely related to P. mellisii, which is a panatropical species with both soredia and isidial initials. However, only soredia are present in P. arnoldii [16].
P. arnoldii is a temperate species [23] that has been recorded from several countries in Europe.

P. crinitum is characterized by the presence of coralloid branched, epically ciliate isidia or often eciliate isidia and stictic acid complex in the medulla. P. mellissii also shows a coralloid isidiate condition, but differs from P. crinitum in having alectoronic and α-collatolic acid [13]. According to Elix [12], P. crinitum resembles P. ochrocrinitum both morphologically and chemically, but the latter shows pigments in the medulla. The specimen of the taxon is untraceable; therefore, the description is based on Kim [24], Divakr and Upreti [13] and Elix [12].
P. crinitum is a cosmopolitan species that is widespread in temperate, tropical regions and even subboreal forests, where high humidity is available [4, 12, 17]. Many European countries have reported the presence of P. crinitum [18]. Some Asian countries such as Japan [19], China [25], and Taiwan [26] have also reported the presence of P. crinitum.
Parmotrema mellissii (C. W. Dodge) Hale, Phytologia 28: 337 (1974)
Parmelia mellissii C. W. Dodge, Ann. Mo. Bot. Gard. 46: 134 (1959).
P. mellissii is characterized by a long abundant marginal cilia, marginal sorediate isidia and the presence of alectoronic acid in the medulla. According to Divakar and Upreti [13], this species shows great variation in the isidia. Coralloid isidia are sometimes difficult to differentiate from isidia, soredia or dactyls. Further, the specimens found from the E. Himalayan region are fertile, whereas the specimens from other regions are sterile. The specimen of the taxon could not be found; therefore, the description is based on Moon [27], Divakar and Upreti [13], and Elix [12].
Outside of South Korea, this species has also been reported in Asia, Africa and Central America.

Remarks
P. eciliatum is characterized by a loosely attached thallus, dichotomous rhizines and the presence of lobules and a stictic acid complex in the medulla. P. eciliatum resembles P. crinitum in its medullary chemical nature, but the latter species has isidia on the upper surface [12]. The specimen of the taxon could not be found; therefore, the description is based on Park [16] and Elix [12].
P. eciliatum has been reported from Asia, Africa and Central America.
