Abstract

A new saprophytic species from southwestern China, namely Clitolyophyllum paraumbilicatum, is described and illustrated based on morphological characteristics and multi-locus phylogenetic analyses from the nuclear ribosomal internal transcribed spacer (ITS), the large subunit of the nuclear ribosomal RNA (nrLSU), the RNA polymerase II second largest subunit (rpb2), and the translation elongation factor 1-alpha (tef1-a). The new species is characterized by its omphalinoid basidiomata with relatively small beige-brown to dark brown and hygrophanous pileus, central and slender stipes, decurrent lamellae, broadly ellipsoid to ovoid or pyriform basidiospores (6–10 × 3.5–5.5 μm), relatively narrow basidia, and flexuose to cylindrical or irregularly branched terminal cells in pileipellis and stipitipellis occasionally with several excrescences or weakly coralloid. Color photos of fresh basidiomata, line drawings of microscopic features and its comparison with allied taxa are presented.
