A new species of Alnicola, A. ramulosa sp. nov., from Japan

Alnicola ramulosa, a new species from Japan, is described. The new section Ramulosae Takah. Kobay. is proposed to accommodate A. ramulosa collected from Shiga Prefecture, Japan. The characters thick-walled pileocystidia and furcate lamellae did not clearly discuss previous authors for the genus Alnicola. A new concept of the genus is presented here based on Alnicola Kuhner emend Takah. Kobay.
