Laboulbeniomycetes (Fungi, Ascomycota) of Denmark Santamaria, Sergi Pedersen, Jan European Journal of Taxonomy 2021 2021-11-26 781 1 425 Thaxt. [704,966,1287,1314] Laboulbeniomycetes Laboulbeniaceae Rhadinomyces GBIF Fungi Laboulbeniales 240 241 Ascomycota genus  MB#4687    Proceedings of the American Academy of Arts and Sciences28: 179 ( Thaxter 1893). –   Typespecies:  R. pallidusThaxt.    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 cristatusThaxt.is regarded as a synonym of  R. pallidus; the other species is  Rhadinomyces gracilis(Thaxt.) I.I.Tav.from Argentinaand Uruguay( Tavares 1985). The segregation of this genus from  Corethromyceshas been widely debated. According to the literature  Rhadinomycesis distinguished from  Corethromycesbecause in the former some antheridial branchlets arise from corner cells of axial cells in the appendage.A thorough revision of the genus  Corethromycesand allied genera is highly desirable, but this will require the help of molecular techniques.
