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.

First record of the sequestrate fungus Neosecotium macrosporum ( Agaricales , Lepiotaceae ) from Mexico

Neosecotium macrosporum, previously known only from two USA records, is reported for the first time in Mexico. Observations of macroand microscopic characters including for the holotype and the Chihuahua collection are presented. SEM photomicrographs illustrating spore ornamentation are included.
