First occurrence of Backusella gigacellularis (Mucorales, Mucoromycota) in a fragment of an upland forest within the semi-arid region of northeastern Brazil

Abstract

In a survey mucoralean fungi in the Brejo da Serra do Benedito, a fragment of Upland Forest in the semi-arid region of Pernambuco, Brazil, a specimen of Backusella gigacellularis was isolated. So far, B. gigacellularis (holotype) had only been isolated from soil in the Cerrado domain, in São Paulo state, southeastern Brazil. This is the second report of B. gigacellularis worldwide, and the first record to northeastern Brazil. A detailed description, as well as the illustration of the specimen, are presented.
