A SYNOPSIS OF THE JAPANESE TAXA OF CLADONIA SECTION COCCIFERAE

抄録

  A revision of all taxa of Cladonia section Cocciferae reported for Japan revealed 22 species. Cladonia deformis (L.) Hoffm. and C. norvegica Tönsberg & Holien are new to Japan. C. floerkeana (Fr.) Flörke is excluded from the flora of Japan since the Japanese material under this name is considered to represent corticate morphs of C. macilenta Hoffm. Many new typifications of taxa described from Japan are made. Lectotypes are also selected for Cladonia despreauxii Tuck. (= C. cyanipes (Sommerf.) Nyl.), C. hookeri Tuck. (= C. bellidiflora (Ach.) Schaerer) and C. macilenta var. ostreata Nyl. (= C. macilenta Hoffm.). The new synonyms include Cladonia botrytes var. exsoluta Nyl. (= C. koyaensis Asah.), C. hitatiensis Asah. (= C. vulcani Savicz), C. pseudodidyma var. simplicior Asah. (= C. pseudodidyma Asah.), C. pseudomacilenta Asah. and C. pseudomacilenta f. subsquamigera Asah. (= C. vulcani). Only C. inobeana Asah. and C. koyaensis remain endemic to Japan.
