Foray report from northwest side of Cook County

Twenty-one mushroom folks found 52 different mushrooms and macrofungi. Conditions were dry but a previous rainstorm encouraged some mushrooms to appear. Four of the mushrooms found are notable collections. Thanks to Rocky and Lorinda for leading the foray.
1) Cantharellus chicagoensis. This is our newly named yellow chanterelle in Chicago. We found variously sized young and mature chanterelles. Several of them were the pale forms that are missing the yellow pigment in the cap. See records on Mushroom Observer.
2) Microstoma floccosum. A distinctively hairy and stalked red cup fungus on twigs. This is our third record for the Chicago Region and first record for Cook County. Previous collections were 1899 in DuPage County and 2011 in McHenry County. See description at Mushroom Expert.
3) Ossicaulis lignatilis. This is an odd mushroom that is somewhat like an oyster mushroom. Our third record for the Chicago Region and second for Cook County. Previous collections were 2014 in Cook County and 1983 at Morton Arboretum, DuPage County. See records on Mushroom Observer.
4) Amanita cf. cinereopannosa. A beautiful and uncommon Amanita. This is the third location for Chicago Region, previously 14 observations in southern Cook County and 5 observations at Indiana Dunes in Porter County. See description at Amanitaceae.org.
