Hyphodontia dimitica and H. subefibulata spp. nov. (Schizoporaceae, Hymenochaetales) from southern China based on morphological and molecular characters

Abstract

Hyphodontia dimitica and H. subefibulata collected from southern China are described as new species on the basis of a combination of morphological and molecular characters. H. dimitica is characterized by its poroid hymenophore, cream to buff fresh pore surface, large pores (2–4 per mm), a dimitic hyphal structure with thick-walled generative hyphae, and ellipsoid basidiospores measured as 3.8–4.6 × 2.8–3.5 µm. Hyphodontia subefibulata is characterized by its hydnoid hymenophore, buff-yellow to dark brown spines when dry, a monomitic hyphal structure with fairly thick-walled generative hyphae, presence of cystidia, and subglobose to broadly ellipsoid basidiospores measured as 3.2–4 × 3.0–3.5 µm. Illustrations and descriptions of these two new species are provided based on the Chinese materials.
