Anatomical and molecular studies on relationships and
evolution of cyphelloid basidiomycetes

Agaricomycetes (Basidiomycota) produce basidiomes of different organisation, e.g. agaricoid (stipitate-pileate) fruiting bodies. The morphologically diverse group includes the still widely unknown, anatomically heterogeneous group of so-called "cyphelloid" fungi with minute (rarely exceeding 1 mm in length or diameter), ± cupulate basidiomes with smooth hymenium. Cyphelloid fungi include roughly 120 species in ca. 40 widely accepted genera while there is an estimated actual diversity of ca. 500 species. Due to their derived morphology the taxonomic placement and the closest relatives of many cyphelloid forms still are dubious.

The relationships of cyphelloid taxa are studied combining the comprehensive examination of anatomical and ultrastructural characters as well as phylogenetic analyses of nuclear and mitochondrial gene regions. The project focuses on putative relationships of cyphelloid forms to non-cyphelloid Agaricomycetes, especially agaricoid taxa with lamellate or poroid hymenophore. It aims at an improved knowledge of the phylogenetic position of cyphelloid taxa and their closest relatives as well as a better understanding of the evolution of the cyphelloid morphology.

Preliminary results of anatomical and DNA-based phylogenetic studies confirm the polyphyly of the cyphelloid fungi and indicate that they have been derived multiple times from within the Agaricales. The putatively closest agaricoid relatives could be identified in several cases.
