Isomucor trufemiae was isolated and described for the first time from soil samples collected in the state of São Paulo State, Brazil, in 2012. Eight years later, we isolated this species in the state of Pernambuco as the second record worldwide and the first record to northeastern Brazil. Isomucor trufemiae URM 8342 was isolated from a soil sample during a study on the diversity of Mucorales in a Montane Atlantic Forest area in the municipality of Bonito, Pernambuco, Brazil, and identified through morphological and molecular analyses (ITS and LSU sequences of rDNA). Aspects of the morphology and distribution of this species are commented in this manuscript.

Two specimens of Mucor variicolumellatus L. Wagner & G. Walther were isolated from soil samples collected in anupland rainforest area located in Pernambuco state, Brazil. Their identity were confirmed by morphophysiology andITS rDNA sequence analysis. Both specimens are distinguished from other species within the Mucor circinelloidescomplex by producing obovoid, ovate and strawberry-shaped columellae. A detailed description and illustration of thespecimens are presented. This is the first record of M. variicolumellatus in the Neotropics.

Mucor nidicola, a mucoralean fungus, was isolated for the first time from a wasp nest in Massachusetts, USA, and then reported in the state of Paraná, Brazil, as an entomopathogenic fungus collected from insects in strawberry crops. This work reports the first occurrence of M. nidicola from soil in the Brazilian Northeast. This species is distinguished from other species by producing erect, unbranched, and once-branched sporangiophores, globose to subglobose columellae, and mostly ellipsoidal sporangiospores, but with some irregular and varying in size and shape.
