Contribution to the study of gasteroid and secotioid fungi of Chihuahua, Mexico

Including the twenty-seven new records reported herein, fifty-seven taxa of gasteroid fungi are now known from Chihuahua. Geastrum schmidelii var. parvisporum represents a new record for the Mexican mycobiota. A nom. nov. is proposed for Agaricus texensis, which is an illegitimate later homonym. The species presented are annotated with observations on macro- and microscopic characters, and SEM photomicrographs illustrating spore and capillitial characters are included for selected taxa.
