NOTES ON SOME EAST-ASIAN SPECIES OF THE LICHEN GENUS FUSCOPANNARIA

Abstract

  The genus Fuscopannaria is shown to be species rich in the East Asian flora, particularly the F. leucosticta group: F. dispersa sp. nov. (China), F. dissecta sp. nov. (Japan), F. poeltii (P. M. Jørg.) P. M. Jørg. (Nepal, Tibet), F. leucosticta (Tuck.) P. M. Jørg. (widespread), F. protensa (Hue) P. M. Jørg. (Japan & Korea) and F. siamensis sp. nov. (Thailand). In addition the F. incisa group is discussed, and three Asian species recognized at the moment: F. incisa (Hue) P. M. Jørg., F. laceratula (Hue) P. M. Jørg. and F. subincisa (Zahlbr.) P. M. Jørg., comb. nov. Also a further species in the F. praetermissa group is described, F. saltuensis sp. nov. from mountain forrests in the Himalayas.

  F. ahlneri (P. M. Jørg.) P. M. Jørg. is reported as new to Russia Primore; F. confusa (P. M. Jørg.) P. M. Jørg. and F. praetermissa (Nyl.) P. M. Jørg. are recorded as new to Japan, and F. sorediata P. M. Jørg. as new to Hawaii, China and India. Keys to critical species complexes are given.

  The F. leucophaea (Vahl) P. M. Jørg. group (subg. Micropannaria P. M. Jørg.) is not so commonly present as in Pacific orth America, and the few available specimen does not allow any further splitting of taxa; on the contrary Pannaria fauriei Hue is considered to be a synonym of F. leucophaea.

  All names are typified.
