Chlorophyllum olivieri
Mycotaxon 83: 416. 2002.
Common Name: none
Cap 5-18 cm broad, subglobose, becoming convex to nearly plane in age; grey-brown to buff brown, cracking into fibrillose scales.
Stipe smooth, cylindrical, 6-18 cm x 0.8-1.5 cm with enlarged base. Veil thick, whitish, with a ragged double edge.
Spores 8.0-11.0 x 5.5-7.0 11 µm, spore deposit white.
Scattered to gregarious in rich leaf litter and humus, fall and winter. Coastal Northwestern California south to Monterey County, rare further south.
Edible and excellent for most persons. Both Chlorophyllum olivieri and Chlorphyllum brunneum are known to cause GI upset in a small population of eaters.
The flesh of Chlorophyllum olivieri when scratched or cut stains orange to pinkish to reddish, most noticeable in the gills and flesh of the stipe. Chlorophyllum brunneum is similar, with an abruptly bulbous stipe base and darker, more contrasty scales on the cap. Chlorophyllum olivieri could also be confused with the toxic Chlorophyllum molybdites, but it has greenish gills at maturity and produces a greenish spore print.
