Atractiellales

The Phleogenaceae are a family of fungi in the order Atractiellales. The family currently contains six genera and around 50 species.

Helicogloea is a genus of fungi in the family Phleogenaceae. Basidiocarps (fruit bodies) are gelatinous, effused or pustular, and (microscopically) have unclamped hyphae and basidia that are auricularioid (tubular and laterally septate). Some species form asexual anamorphs producing conidia. The widespread genus contains more than 20 species.

Phleogena is a fungal genus in the Phleogenaceae family. The genus is monotypic, containing the single species Phleogena faginea and is found mostly widespread in northern temperate areas, but is occasionally found in southern areas.

Atractiella is a genus of fungi in the family Hoehnelomycetaceae. The widespread genus contains seven species. Basidiocarps (fruit bodies) are minute and stilboid (pin-shaped) Microscopically they produce auricularioid (laterally septate) basidia. Molecular research, based on cladistic analysis of DNA sequences, has shown that the genus is monophyletic (a natural grouping).

Basidiopycnis is a fungal genus in the family Hoehnelomycetaceae. The genus is monotypic, containing the single species Basidiopycnis hyalina. The species forms minute pycnidial basidiocarps (fruit bodies) in bark beetle tunnels. Teleomorphs produce auricularioid (laterally septate) basidia, whilst anamorphs produce asexual conidia. Basidiopycnis hyalina was described from Germany and is also known from Italy and Switzerland. Anamorphic fruit bodies collected in Canada were given the name Basidiopycnides albertensis, but are currently considered conspecific with the European species.
