First record of Tulostoma gracilipes (Agaricales, Agaricaceae) for the Americas

Tulostoma gracilipes is reported for the first time in the Americas. Since this species was only known in the type locality of South Africa, this record from Mexico represents the second worldwide. Observations of macro- and microscopic characters for the holotype and Sonoran collection are presented. SEM photomicrographs illustrating spore ornamentation are included.
