characterized by grayish brown cap that often becomes centrally depressed, broad whitish gills, grayish brown stem, and growth on burnt soil; Smith(15) mentions some confusion in the species concept in Europe: the Friesian species Agaricus maurus has a dry cap and long-decurrent gills, but the concept accepted in Europe is that of Ricken (1915) which is the same as the one he describes in Smith(15) as Omphalina maura, but cannot be regarded as the same as one he found in Michigan that corresponds to one illustrated by Lange from Denmark; there are difference between descriptions of spores, some stating that they are smooth and some that there are fine amyloid warts; M. maura common in western United States, (Smith), M. maura material examined from WA, OR, ID, QC, (Bigelow(6)), OR (Kauffman), collections from BC at Pacific Forestry Centre and University of British Columbia, reported from AB by Schalkwijk-Barendsen(1), NS, ME, (Bigelow(4))also in Europe and reported from Asia and North Africa, (Breitenbach(3))
