Classiculomycetes

The Classiculomycetes are a class of fungi in the Pucciniomycotina subdivision of the Basidiomycota. The class contains a single order, the Classiculales, which in turn contains the single family Classiculaceae. The family contains two monotypic genera.

They belong to a group called "aquatic Hyphomycetes" which grow on submerged decaying plant matter. This is only an informal descriptive group which is divided phylogenetically between asco types (the great majority) and basidio types. The Classiculomycetes belong to the small basidio minority.
