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.

The Upland Forest areas are enclaves of humidForest surrounded by vegetation of Caatinga, forming “islands” of rainforest in the middle of the semi-arid region that present different climatic conditions in relation to humidity, temperature and vegetation in comparison with areas of Caatinga (Tabarelli & Santos 2004)
Considering the elevated diversity and endemism of plants in the Atlantic Forest domain, it is probable that the current knowledge of diversity of mucoralean species in soils of the Upland Forest areas is insufficient

Summary

Introduction

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. Considering the elevated diversity and endemism of plants in the Atlantic Forest domain, it is probable that the current knowledge of diversity of mucoralean species in soils of the Upland Forest areas is insufficient 34 species of Mucorales have been reported for the Brazilian Upland Forest areas, including six recently described new species (Hyde et al 2016; Tibpromma et al 2017; Lima et al 2018b) and two first occurrences for Brazil (Santiago & Maia 2010; Alves et al 2017).
