Chlorophyllum olivieri

Vellinga recognizes this species as resembling Chlorophyllum rachodes (= Macrolepiota rachodes var. rachodes) in general habit, but differing in the olivaceous drab, gray or brownish scales that do not contrast with the background, and the slightly smaller spores, being widespread in Europe (spruce and deciduous woods), and from oak habitats in the Pacific Northwest. According to Vellinga, illustrations include those for Macrolepiota rachodes var. rachodes in Breitenbach, and for Lepiota rhacodes in Phillips - Mushrooms and other fungi of Great Britain and Europe. The descriptions given with these illustrations are used below in addition to the one from Sieger. Chlorophyllum olivieri is often found on foray lists in WA and BC and there is a collection from BC at the University of British Columbia.
