Catabotrys was erected by Theissen & Sydow (1915) based on Bagnisiella palmarum Pat. and has been placed in Dothideaceae (Dothideae). Petrak (1934) transferred Catabotrys to Hypocreales because its thin-walled asci and bright coloured stroma are similar to the latter. Seaver & Waterston (1946) synonymized an earlier name Hypoxylon deciduum as Catabotrys deciduum. Morphologically, Catabotrys is characterized by superficial, erumpent, multi-loculate stromata, and simple hyaline, 1-celled spores. Catabotrys deciduum is illustrated in this entry (Fig. 1).
Type species: Catabotrys palmarum (Pat.) Theiss. & Syd., Annls mycol. 13(3/4): 297 (1915).
Other accepted species: Species Fungorum – search Catabotrys.
