Abstract

In this study, Gloeosoma cremeum is described and illustrated as a novel species based on morphological characteristics and phylogenetic analyses of internal transcribed spacer (ITS) regions and the large subunit (nLSU) of nuclear ribosomal RNA genes. The species is characterized by smooth, membranaceous basidiomata with a cream hymenial surface, and finely echinulate, ellipsoid to semilunate basidiospores (23.5–32 × 16–20.5 µm). The phylogenetic tree inferred from ITS+nLSU sequences revealed that the new species was nested within the genus Gloeosoma within the family Stereaceae, forming a monophyletic lineage and grouping with G. mirabile.
