Brazilian semi-arid ascomycetes I: New and interesting records of hysteriaceous ascomycetes

Abstract

During an investigation of ascomycetes carried out in one area of Caatinga and three enclaves of the Atlantic Forest in the semi-arid region of Brazil, we found ten interesting species of hysteriaceous ascomycetes. Psiloglonium clavisporum and Rhytidhysteron opuntiae are new records for South America and Anteaglonium abbreviatum, Hysterium angustatum and Hysterobrevium smilacis are new records for Brazil. All species are described, illustrated and discussed.
