Supplemental description as Ascodinium parvum:
Cookson and Eisenack, 1960, p. 5:
Description:
Shell flat, more or less rhombic in outline, with a blunt or sharply pointed apex and a sharply pointed antapex; girdle equatorial and circular. Capsule large and four-sided or occasionally oval, almost filling the shell. Lid of pylome circular, but, since the whole apex is finally detached, the remaining portion of the epitheca has a truncate appearance. Shell smooth, transparent; wall of capsule thin and smooth.
