The genera Brianaria (Psoraceae) and Micarea (Pilocarpaceae) in Japan, with reports on other interesting species in Asia

Coppins, Brian J.; Kashiwadani, Hiroyuki; Moon, Kwang Hee; Spribille, Toby; Thor, Goran


An examination of collections from Japan has increased the number of Brianaria and Micarea species known from that country from eight to 19, including one new species, M. rubioides Coppins (also from Malaysia and the Philippines). Eleven species are reported as new to Japan (M. botryoides (Nyl.) Coppins, M. denigrata (Fr.) Hedl., M. erratica (Korb.) Hertel et al., M. hedlundii Coppins, M. lithinella (Nyl.) Hedl., M. micrococca (Korb.) Gams ex Coppins and M. misella (Nyl.) Hedl.) or new to Asia: M. byssacea (Th. Fr.) Czarnota et al., M. deminuta Coppins and M. xanthonica Coppins & Tonsberg (new to Asia; Japan); M. nitschkeana (J. Lahm ex Rabenh.) Harm. (new to Asia; South Korea). The presence of Micarea prasina s. str. from Japan needs to be confirmed; no collection was found in this study. Additional collections from South Korea and Sri Lanka are also reported, including the new species M. ceylanica Coppins from Sri Lanka. The identity of M. synotheoides (Nyl.) Coppins, originally described from Japan, has been resolved, resulting in the renaming of Western European material, previously under that name, as M. longispora Coppins. Micarea coreana Lokos et al. is reported here as a synonym of M. erratica. The type of Lecidea inopinula Nyl. requires the new combination Micarea inopinula (Nyl.) Coppins & T. Sprib. to replace Micarea prasinella (Jatta) I. M. Lamb.
