Foray 2016-05-28

Foray report from forest preserve at north edge of Cook County.

The recent rains brought out a good variety of spring mushrooms. Twenty folks and kids looked through the maple-oak forest. There were many toads out this morning. Two large but old black morels were found. Wood ears were again found but few dryad saddles. Auricularia angiospermarum is the new name for our wood ear that grows on hardwood. Auricularia americana is very similar but grows on conifer wood (found out east). Auricularia auricula-judae is found in Europe. Odd mushrooms again included the springtime Gymnopus subsulphureus and Gymnopus semihirtipes. The rarest mushroom was Polyporus craterellus, which looks like a small dryad saddle but has smaller scales and the stem remains pale (not turning dark). This location has the parasitic plant Conopholis americana, known as American cancer-root or squawroot or bear corn. There were 47 different fungi found plus 3 kinds of slime molds. Thanks to Rocky for leading the foray.
