Race 1, atranorin, zeorin, leucotylic acid and its derivatives, and secalonic acid A. Race 2, atranorin, zeorin, leucotylin and its derivatives, and secalonic acid A.</p><p>Myelochroa aurulenta is characterized by a foliose thallus with pustules or granular soredia and a yellow medulla containing secalonic acid A, zeorin, and leucotylic acid or leucotylin.</p><p>The present species is easily distinguished from allied species of the genus by the presence of soredia. Soralia are variable in shape, varying from pustules to farinose soredia. They are formed laminally and subterminally; laminal soralia are rounded and often diffusing, and subterminal soredia often inflated, forming capitate soralia.</p><p>Hale (1976) considered that Parmelina aurulenta (= Myelochroa aurulenta) produces leucotylic acid as the major substance. According to Kurokawa and Arakawa (1997), leucotylic acid was demonstrated in 24 of 25 specimens collected in Japan, while leucotylin was detected from only one specimen. The Korean materials show a similar tendency with leucotylic acid demonstrated in 40 of the 43 specimens and leucotylin detected in only three specimens; however, no morphological differences have been found between the two chemical races, and the chemical difference seems to have no taxonomic value.</p><p>Park (1990) described Myelochroa coreana Y.S. Park based on a specimen collected at Mt. Sorak, Korea. As discussed by Moon (1999), the holotype specimen preserved in DUKE shows typical morphological characters found in M. aurulenta . In addition, specimens examined by her include the two chemical variations shown above. Therefore, M. coreana is simply reduced to a synonym of M. aurulenta .</p><p>Moon et al. (2013) described Myelochroa ibukiensis K.H. Moon, Kashiw. &amp; K. Kobayashi based on a specimen collected at Ibuki, Maebara-city, Japan. They stressed the presence of red dots that appeared to be pigments of the medulla; however, detailed study of the holotype reveals that the red dots are derived from the juvenile colony of a parasitic fungus ( Marchandiomyces corallines), which does not belong with the mycobiont of the holotype. All other morphological and chemical characters are those found in M. aurulenta . Thus, M. ibukiensis is reduced to a synonym of M. aurulenta .</p><p>In Korea, M. aurulenta has been reported as Parmelia aurulenta (Park, 1979; Lee, 1987; Ri and Hyun, 1988; Ri, 1988; 2000), Parmelina aurulenta (Hale, 1976), M. coreana (Park, 1990) and M. aurulenta (Park, 1990; Moon, 1997; 1999; Kashiwadani et al., 2002; Hur et al., 2004; Jayalal et al., 2012).</p><p>Myelochroa aurulenta is widely distributed in temperate and subtropical regions in the world excepting Europe, having been reported from Japan, eastern and southeastern Asia including Siberia, Korea, mainland China, Taiwan, Hong Kong, Pakistan, Nepal, India, Sri Lanka, Java, the Philippines, New Guinea, eastern Africa including Madagascar, Hawaii, Canada, the U. S. A., Mexico and South America (Hale, 1976) and Australia (Kurokawa and Arakawa, 1997). This species was also reported from Thailand (Moon et al., 2000), Fiji (Elix, 2001) and Turkey (Yazici et al., 2010).</p><p>Myelochroa aurulenta is apparently widely distributed throughout the Korean peninsula.</p><p>Representative specimens examined.

Morphologically this species very much resembles M. galbina, which differs by the production of galbinic and salazinic acids. In addition, it is rather loosely attached to the substrate, whereas M. galbina is always tightly attached.</p><p>In 2012, Jayalal et al. reported M. xantholepis (Mont. &amp; Bosch) Elix &amp; Hale from South Korea and stressed that their specimens have dimorphic lobes and a pale yellow medulla. Although the Korean specimens used by them have newly found small lobes (Fig. 1), these are not the same as those found in M. xantholepis, which has dichotomously divided lobules (Fig. 2) toward the lobe margins (Hale, 1976). In addition, the yellow medulla of the Korean materials is different from the characteristic orange-yellow medulla observed in M. xantholepis (Hale, 1976) . Therefore, these specimens should be simply identified with M. irrugans .</p><p>Cho and Lee (1980) reported the occurrence of Myelochroa denegans (Nyl.) Elix &amp; Hale under a name of Parmelia denegans . Although the specimen examined by them has disappeared and is unable to be traced, it is highly possible that this specimen could be identified with M. irrugans as they indicated the absence of soredia and isidia, and the presence of K+ yellow medulla.</p><p>Myelochroa irrugans shows extensive variation in regard to thickness of the thallus, lobe width and size of mature apothecia. Among the specimens of this species, those with a narrow and thin thallus were once treated under Parmelia subaurulenta (= M. subaurulenta) and those with small apothecia as P. subaurulenta var. myriocarpa (Asahina, 1951); however, these morphological characters found in the present species have no taxonomic value for separating species as already discussed by Kurokawa and Arakawa (1997).</p><p>This species has two chemical races characterized by differences in terpenoides (the leucotylic acid containing race and the leucotylin containing race). Both races are commonly found throughout the Korean peninsula.</p><p>Myelochroa irrugans is one of the common species of Myelochroa in Korea. It has been reported from Korea as Parmelia irrugans (Lee, 1987), as Parmelia subaurulenta (Asahina, 1951; Kim, 1965; 1979; Park, 1976; Cho and Lee, 1980; Ban, 1983; Lee, 1987; Ri, 1988), as Parmelia homogenes (Kim, 1965; Cho and Lee, 1980; Ri, 1988), as M. crassata (Park, 1990), as M. subaurulenta (Park, 1990; Huneck et al., 1994) and as M. irrugans (Park, 1990; Moon, 1998; 1999; Kashiwadani et al., 2002; Hur et al., 2004; Jayalal et al., 2012).</p><p>This species seems to be endemic to eastern Asia, having been reported from China, India, Japan, Nepal, Sakhalin, Sri Lanka, Taiwan and Thailand (Kurokawa and Arakawa, 1997; Jayalal et al., 2012).

Although the medulla of M. perisidians varies from pale yellow to almost white, that of M. indica is constantly white.

(2012); however, Park (1990) reported that the specimens contain secalonic acid A and have lobes of 1-3 mm wide. Therefore, the specimens should be identified with M. perisidians rather than M. indica . We re-examined all materials treated under M. indica by Jayalal et al. and confirmed that all specimens contain atranorin, zeorin, leucotylin and secalonic acid A, characteristic chemical features for M. perisidians .</p><p>This species is widely distributed in Asia, having been recorded from India, Sri Lanka, Thailand, Japan (Hale, 1976; Kurokawa and Arakawa, 1997) and Korea.
