Abstract
Specimens of Crinipellis and Marasmius (Marasmiaceae) collected from Beijing, North China, were studied by morphological and molecular methods. Phylogenetic analyses were performed separately for the two genera based on ITS sequence data. Two new species, C. deutziae and M. pinicola, were found, and C. rhizomaticola was reported from China for the first time. Crinipellis deutziae is characterized by small basidiocarps, large and variably shaped basidiospores measuring 8.8–11 × 7.5–9.5 µm, the presence of both cheilocystidia and pleurocystidia, and growing on Deutzia parviflora. Marasmius pinicola is characterized by small basidiocarps, cylindrical, reniform to phaseoliform basidiospores measuring 6–8 × 3.5–4.2 µm, often capitate cheilocystidia, and pleurocystidia, and growing on fallen leaves of Pinus tabuliformis. Descriptions and illustrations are provided for the three species. The results of this study contribute to the knowledge of the species diversity of macro-fungi in Beijing.
