Abstract

Hyphodiscus hyaloscyphoides sp. nov. and its Catenulifera anamorph are described and illustrated. The teleomorph is morphologically most similar to H. hymeniophila but distinguished by dull white-colored apothecia. The anamorph is characterized by its minute conidiogenous structure with small subglobose conidia. The monophyly of Hyphodiscus was strongly supported in our molecular phylogenetic analyses using the D1–D2 region of large subunit of nuclear rDNA, but the phylogenetic relationships with other members of Hyaloscyphaceae were not strongly supported. In addition, Hyphodiscus hymeniophilus, one of the close relatives of H. hyaloscyphoides, turned out to be a heterogeneous assemblage based on the ITS region, which requires further research for taxonomic revision.
