Some interesting Gasteromycetes (Basidiomycota) in dry areas from northeastern Brazil

Abstract

Some xerophyles gasteroid fungi from 'caatinga' vegetation are joined here. Several specimens belonging to four species were identified: Astraeus hygrometricus (Pers.: Pers.) Morg., Myriostoma coliforme (With.: Pers.) Corda, Podaxis pistillaris (L.: Pers.) Fr. emend. Morse and Tulostoma exasperatum Mont. All of these species, except P. pistillaris, represent first records from the caatinga region. Descriptions of macro and microscopic features are given including taxonomic and ecological considerations.
