Notes on Tulostoma volvulatum and T. giovanellae

A detailed examination of the rediscovered type of Tulostoma volvulatum leads to the conclusion that it represents an earlier name for T. giovanellae. The former name will be proposed for rejection and the latter for conservation. Tulostoma volvulatum s. auct. becomes T. obesum.

Notes on type materials of Tulostoma. Some species with mixed holotypes

A study of the macroscopic and microscopic characters of type material of Tulostoma leiosporum, T. exitum, T. operculatum and T. puncticulosum showed their heterogeneity. An attempt was made to resolve the taxonomic problems involved in the selection of lectotypes, and new synonymies are proposed. SEM photographs of spore ornamentation are provided.
