Fulvifomes parviungulatus (Hymenochaetales, Basidiomycota), a new species from China based on morphological and molecular evidence

Abstract

Fulvifomes parviungulatus sp. nov. is described and illustrated from China based on morphological characters and phylogenetic analyses. The sequences of the internal transcribed spacer (ITS) region and nuclear-encoded large subunit rRNA gene (28S) were employed. Fulvifomes parviungulatus is characterized by the perennial, small and ungulate basidiocarps, crusted, smooth pileal surface, 4–5 pores per mm with thick dissepiments, a dimitic hyphal system with interwoven skeletal hyphae, absence of ventricose cystidioles, collapsed hymenium in the studied material and ellipsoid, yellowish brown, thick-walled, smooth basidiospores measuring 4.2–4.7 × 3.5–4 μm. The new species was compared with its related taxa and a molecular study supports it with in the genus of Fulvifomes.
