Two new species of Metacampanella (Agaricales, Marasmiaceae) from China and Mongolia.

Metacampanella is an important genus in the Marasmiaceae family. We collected specimens during our investigations in China and Mongolia. Through morphological and molecular phylogenetic analyses, we identified two new species of this genus: Metacampanellasubtricolor and Metacampanellacoprophila . In addition, we identified Metacampanellatricolor as a novel combination. Molecular systematic studies support these results. Illustrated descriptions, taxonomic discussions, and keys to the genus are provided.
