Stropharia and Hypholoma
Similarities and differences
Stropharia have well developed persistent veil, attached gills,
and dark (purple-brown to black) spores.
The cap is usually viscid and some shade of yellow, orange red, blue or white.
The veil forms a distinct annulus (ring) on the stalk, and many times leaves copious remnats on the cap
Hypholoma have dark brown to purple-brown spore print, the absence of prominent veil remnants
other than an occasional cortina or a few wisps of tissue on the cap margin).
While the size of the stipe can be similar, in most cases Stropharia
will be taller and wider than Hypholoma. Stropharia tends to have fairly
wide gills while Hyphaloma has somewhat narrow gills.
While Hypholoma may be fibrillose, Stropharia is often floccose
(i.e. covered with woolly tufts)- From: Dick B..
