Marasmioid and gymnopoid fungi of the Republic of Korea. 2. <I>Marasmius </I> sect. <I>Globulares</I>

Abstract

Seven species of Marasmius sect. Globulares with smooth pileipellis cells (sect. Globulares s. Singer) have been collected in the Republic of Korea (South Korea) to date, viz. M. aurantioferrugineus, M. brunneospermus, M. maximus, M. nivicola, M. purpureostriatus, M. wynneae and M. fusicystidiosus. Descriptions of their macro- and microscopic features with a discussion of similar taxa are given. Their taxonomic position was confirmed using DNA data. Marasmius fusicystidiosus is described as a new species. A key to aid in their identification is also provided.

Marasmius albopurpureus, a new species of section Globulares from Baili Island, China

“…Marasmius laticlavatus Wannathes et al (Wannathes et al 2009b), originally reported from Thailand, differs from M. albopurpureus in its plicate pileus with a brown disc and pallid grayish cream margin, cream well-developed lamellae, and larger basidiospores (mean 30.4×5.6 μm). Marasmius purpureostriatus Hongo (Hongo 1958;Antonín et al 2010), firstly discovered from Japan, differs from the new species in forming a conical pileus, darker violet and full-developed lamellae, and wider spores (21-25×5-6.5 μm). Marasmius sparsifolius Chun Y.…”

“…The following species are also similar to this new species to some extent, but their differences are more obvious. Marasmius bekolacongoli Beeli (Beeli 1928;Antonín et al 2010), a widespread species in tropical Africa, has a much larger [(10)36-67(100) mm diam.] pileus and longer stipe [50-150×2.5-6(10) mm].…”

“…PCR cycling condition and DNA sequencing was carried out according to the protocol described by Antonín et al. [ 12 , 17 ]. For the nrITS region, PCR was performed with a 30 s denaturation at 94 °C, a 30 s annealing at 56 °C and a 1 min extension at 72 °C and was run with 35 cycles in the first denaturation and the last extension.…”

A new species and a new record of Marasmius from China

“…Singer 1964Singer , 1976Desjardin & Horak 1997, Desjardin & Ovrebo 2006, Antonín 2003, Antonín & Buyck 2006, Antonín & Noordeloos 2010. Recently the morphological and molecular studies of Asian Marasmius species were extensively conducted (Tan et al 2009, Wannathes et al 2009, Antonín et al 2010a, whereas the species of Marasmius from China are still poorly known. Although Karsten (1892) reported the first records of Marasmius from China, the reported species M. dryophilus (Bull.)…”
