Cortez, Vagner Gularte, Marcelo Aloisio Sulzbacher, Iuri Goulart Baseia & Rosa Mara Borges da Silveira. Two little known gasteroid fungi from Santa Catarina State, southern Brazil. Mycotaxon 106: 297-302. 2008.

ABSTRACT: Geastrum ovalisporum and Tulostoma rickii are reported for the first time from the State of Santa Catarina in southern Brazil. Geastrum ovalisporum is characterized mainly by ovoid basidiospores, a unique feature in the genus. Tulostoma rickii, a rare and poorly known species from Rio Grande do Sul State, is diagnosed by its bulbous (pseudo-volvate) stipe base and reticulate basidiospores. Illustrations (including scanning electron micrographs of the basidiospores) accompany full taxonomic descriptions and distributional notes.
