Background:

Queletia is a genus considered rare and little studied. Q. mirabilis is the most recognized species, registered from Europe and North America. In Mexico, several contributions have been made on Tulomastaceae, with records of all genera except Queletia, which is cited for the first time for the country.

Objective:

Register the genus Queletia for the Mexican mycobiota under Q. mirabilis.

Methods:

Material collected from the state of Nayarit and deposited in the mycological collection of the IBUG herbarium was studied. For the macro- and micromorphological study the conventional techniques in mycology were followed, and the use of specialized literature for its determination.

Results and conclusions:

Morphological description of Q. mirabilis, photographs of basidioma and microscopic structures of taxonomic importance are presented. In several Mexican states such as Nayarit, it is necessary to increase the explorations for a better knowledge of the country mycobiota.
