Abstract
Two new species of Agaricales, Deconicaflavum and Entocyberoseoalbus, are described from Mount Tianmu, Zhejiang Province, Eastern China. Two new species are distinct and monophyletic based on morphology and phylogenetic analyses. Deconicaflavum 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. Entocyberoseoalbus 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.
