Type species: B. coronata Maire

Brief description

Monoecious. Receptacle three-celled ( Fig. 46F ). Cell III separated from cell II by an oblique septum; not in contact with cell I and laterally adnate to the base of the perithecial stalk-cell (VI). Primary appendage free, consisting of two superposed cells and a terminal, usually spinose ( Fig. 46H , sx), flask-shaped antheridium ( Fig. 46F , an). Perithecium with five cells in each vertical row of outer wall cells.

Remarks

The genus consists of 15 species, of which two in Europe, one in Denmark. The most recently described species is B. denotata (Haelewaters et al. 2014) . Benjamin (2001) redefined the genus Autophagomyces , transferring some species to Bordea and describing the genus Rossiomyces .
