Genus Stichomyces Thaxt.

MB#5233

Proceedings of the American Academy of Arts and Sciences 37: 37 ( Thaxter 1901b). –

Type species: C. conosomatis Thaxt.

Brief description

Monoecious. Receptacle three-celled. Cell II and occasionally cell III giving rise to perithecia. Primary appendage free, forming a main axis like a prolongation of the receptacle; consisting of several superposed cells bearing lateral fertile or sterile branches borne on upper, opposite corner cells. Antheridia flaskshaped, solitary or clustered on branches. Perithecium with four cells in each vertical row of outer wall cells.

Remarks

The genus consists of three species: S. capensis Thaxt. , S. sumatrae Thaxt. , and the generitypus S. conosomatis , which is the only European species. This genus belongs to a group of genera closely related to Corethromyces , and revision is required to verify its distinctiveness. Stichomyces was isolated because cell III is sterile or gives rise to a perithecium, seldom to antheridial branchlets which are more abundant on nearby cells of the appendage above. In Rhadinomyces , cell III bears antheridial branchlets which are less often formed on following cells of the appendage above. In Corethromyces , antheridial branchlets do not arise from corner cells as in Stichomyces and Rhadinomyces . As can be understood, the characteristics do not seem very substantial.
