Morpho-molecular analysis of two new species Deconica and Entocybe in Agaricales from Mount Tianmu, China

Abstract

Two new species of Agaricales, Deconica flavum and Entocybe roseoalbus, are described from Mount Tianmu, Zhejiang Province, Eastern China. Two new species are distinct and monophyletic based on morphology and phylogenetic analyses. Deconica flavum differs from other Deconica species in that the pileus is brow shallow in the center and stipe with yellowish white fibrils, scatted on litter under coniferous and broad-leaved mixed forest at 1162 m. Entocybe roseoalbus is distinguished from other species of Entocybe by nearly blue pileus and pinkish-white stipe, scatted on humus in similar forest conditions at 1025 m. The differences are discussed between the two new taxa and their similar species morphologically, and related species phylogenetically.
