Hoehnelomycetaceae
The Hoehnelomycetaceae are a family of fungi in the order Atractiellales. The family currently contains three genera and ten species. Basidiocarps (fruit bodies) are minute and ether stilboid (pin-shaped) or pycnidioid (flask-shaped). Microscop ...
. The widespread genus contains seven species.
Basidiocarps
In fungi, a basidiocarp, basidiome, or basidioma () is the sporocarp of a basidiomycete, the multicellular structure on which the spore-producing hymenium is borne. Basidiocarps are characteristic of the hymenomycetes; rusts and smuts do no ...

Microscopically they produce auricularioid (laterally septate) basidia.

A molecule is a group of two or more atoms that are held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions that satisfy this criterion. In quantum physics, organic chemistry, ...
research, based on cladistic
Cladistics ( ; from Ancient Greek 'branch') is an approach to biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is ...
