Brief description

Monoecious. Receptacle consisting of 6–8 cells viz.: a basal cell (I), 2–4 cells Ia, two cells II, and one cell III. Cell III subtends two broad cells which each bear two bell-shaped antheridia. The perithecium has two adjacent vertical rows of outer wall cells with 4–5 cells, and other two rows with 7–8 cells.

Remarks

Monotypic. Closely related to Chitonomyces from which it can be separated by the perithecial wall cell arrangement and appendage characteristics.
