Leão-Ferreira, Sheila Miranda & Luís Fernando Pascholati Gusmão. Conidial fungi from the semi-arid Caatinga biome of Brazil. New species of Endophragmiella and Spegazzinia with new records for Brazil, South America, and Neotropica. Mycotaxon 111: 1–10. 2010.

ABSTRACT: Two new species found on dead bark and fruit in Brazilian semi-arid region are described and illustrated. Endophragmiella tuberculata sp. nov.  is characterized by obovoid, 1-septate, verrucose conidia, and can be distinguished from similar Endophragmiella species by the distal cells of its conidia with conspicuous tubercules. Spegazzinia flabellata sp. nov.  has two types of conidia: a—globose to subglobose, simple, strong spinulose and b—co-planate, with four quadrangular cells, finely spinulose; it can be separated from earlier described Spegazzinia species by a-type conidia with conspicuous spines. Dictyoarthrinium sacchari is reported for the first time from Brazil. Furthermore, E. collapsa and E. dimorphospora are new records for Neotropica and South America respectively.
