Type species: S. lathrobii Thaxt. View in CoL

Brief description

Monoecious. Receptacle three-celled. Cells II and III separated by a vertical or oblique septum. Primary appendage free, consisting of several superposed cells bearing on the inner side short lateral branches with intercalary and terminal antheridia; a spinous process directed outwards is found on the preapical region. Perithecium with five cells in each vertical row of outer wall cells.

Remarks

This genus consists of four or five species, depending on whether Sphaleromyces montevideensis (Speg.) I.I.Tav. ( Tavares 1985) belongs here. Only S. lathrobii is known from Europe. No new species have been added after Thaxter’s descriptions. Distinctiveness of this genus from Corethromyces will remain debatable until the whole set of similar genera (e.g., Diphymyces , Rhadinomyces , Stichomyces , etc.) may be studied and compared on the basis of modern techniques.
