MB#4687 Proceedings of the American Academy of Arts and Sciences 28: 179 ( Thaxter 1893 ) . – Type species: R. pallidus Thaxt. Brief description Monoecious. Receptacle three-celled. Primary appendage free, consisting of several superposed cells bearing lateral sterile branches. Clustered antheridia on branchlets arising from corner cells on cell III and lower cells of appendage axis. Perithecium with four cells in each vertical row of outer wall cells. Remarks The genus consists of two or three species depending on whether Rhadinomyces cristatus Thaxt. is regarded as a synonym of R. pallidus ; the other species is Rhadinomyces gracilis (Thaxt.) I.I.Tav. from Argentina and Uruguay ( Tavares 1985 ). The segregation of this genus from Corethromyces has been widely debated. According to the literature Rhadinomyces is distinguished from Corethromyces because in the former some antheridial branchlets arise from corner cells of axial cells in the appendage.A thorough revision of the genus Corethromyces and allied genera is highly desirable, but this will require the help of molecular techniques.
