Confertotrama rajchenbergii (Gorjón & Hallenb.) Nakasone & S.H. He, comb. nov.
MycoBank number: MB; Index Fungorum number: IF; Facesoffungi number: FoF 11675;
≡ Gloeocystidiellum rajchenbergii Gorjón & Hallenb., Mycol. Progr. 12(2): 186 (2013).
Notes: The species was recently described from Chile and is morphologically similar to other species of Confertotrama by having compact texture, thick-walled gloeocystidia and narrowly ellipsoid to cylindrical basidiospores (Gorjón and Hallenberg 2013). In the ITS tree, the species formed a strongly supported lineage with Gloeocystidiellum aspellum, G. compactum and G. formosanum (Gorjón and Hallenberg 2013). Thus, we propose this combination here.
