Bourdotia is a genus of fungi in the order Auriculariales. Basidiocarps (fruit bodies) are effused, waxy, and occur on dead wood. Macroscopically they resemble waxy species of Exidiopsis, but are distinguished microscopically by the presence of gloeocystidia and "myxarioid" basidia (vertically sepate with an enucleate stalk cell). Only the type species, described from France, is currently confirmed as belonging to the genus.

Taxonomy
editHistory
editBourdotia was originally published in 1908 by Italian mycologist Giacomo Bresadola as a subgenus of Sebacina, a genus then used for any species with tremelloid (vertically septate) basidia and effused basidiocarps. It was raised to the level of genus in 1913. Many additional effused species with gloeocystidia were subsequently described in Bourdotia until 1963 when Canadian mycologist E. Robena Luck-Allen transferred the majority into the genus Basidiodendron which she considered distinct.[1]
Current status
editMolecular research, based on cladistic analysis of DNA sequences, has confirmed Luck-Allen's separation of Basidiodendron and Bourdotia.[2][3] Sequencing of the type species, Bourdotia galzinii, has shown that the genus is close to Ductifera (which also has gloeocystidia) and may not be distinct.[2]
