Two new species of Cyclocybe (Agaricales, Tubariaceae) from China

Abstract

Cyclocybe encompasses 12 species which are distributed worldwide. In this study, two new species named C. suberebia and C. dinggyensis are introduced from China. Phylogenetic analyses based on nrITS, nrLSU, tef1-α, and rpb2 data show their placement within Cyclocybe in two distinct lineages. Cyclocybe suberebia is characterized by its dark brown to light brown pileus, smaller spore size, clampless hyphae. Cyclocybe dinggyensis is characterized by a slender basidioma, tetrasporic basidia and clampless hyphae. Descriptions, colour photographs and line drawings of both new species are presented.
