Remarks (internal):Gloeocystidiopsis cryptacantha is imperfectly known, but presumably with a neotropical distribution.
There are at least three species that seem to be extremely similar if not the same to G. cryptacantha viz. Gloeocystidiellum triste Hjortstam & Ryvarden (described from Argentina), Gloeocystidiellum fimbriatum Burds. et al. (from USA, Florida), and Gloeocystidiopsis salmonea (Burt) Boidin et al. (from West Indies, Grenada). Microscopically all have almost the same details such as gloeocystidia (though with different sulphovanillin reaction), hyphae and spores,
