Abstract
Based on morphological characteristics and molecular evidence, two new species of Panellus, P. bambusicola and P. yunnanensis, are described and illustrated from Yunnan Province, southwestern China. Both species are characterized by white and gelatinous basidiocarps, poroid hymenophore which is concolorous with the pileal surface, a monomitic hyphal system with slightly thick-walled tramal hyphae. P. bambusicola has oblong ellipsoid to ellipsoid basidiospores measuring 6–7.2 × 3–3.8 μm, whereas P. yunnanensis has ellipsoid to broadly ellipsoid basidiospores measuring 6.5–8.5 × 3.8–4.5 μm. In addition, samples of P. bambusicola and P. yunnanensis formed two distinct phylogenetic lineages based on the internal transcribed spacer regions (ITS) and nuclear large subunit ribosomal RNA gene regions (nLSU) sequences.
