Abstract

LIZARRAGA, Marcos et al. The genus Disciseda (Agaricales, Agaricaceae) in the Central Plains of the Chihuahuan Desert, Mexico. Rev. Mex. Mic [online]. 2010, vol.32, pp.41-47. ISSN 0187-3180.

As a result of seasonal sampling over one year at 10 sites in the Central Plains of the Chihuahuan Desert, a study of the genus Disciseda is presented. Twenty-nine collections were studied and from them five species were identified: D. bovista, D. candida, D. hyalothrix, D. stuckertii and D. verrucosa. Although all species were observed in microphyllous desert scrub, D. hyalothrix was the most frequently collected species. The majority of the specimens were collected under or close to Prosopis glandulosa in sandy soils. D. bovista and D. stuckertii are new records for the Chihuahuan mycobiota. The phenology and chorology along with the macro and microscopic characters of each species, including spore ornamentation under SEM, are outlined.

Keywords : Agaricomycetes; Lycoperdaceae; taxonomy; chorology.
