Gymnopus dryophilus at Shad Landing in Worcester Co., Maryland (5/21/2013). Per Lance Biechele: This mushroom is often considered a 'weed' species and more than 20 variants are cited under the old name, Collybia dryophila. To complicate matters more, in 1983, mating 43 collections of C. dryophila revealed four distinct taxa (Vilgalys & Miller). Such details only enforce the difficulties of mushroom identification by amateurs. Photo by Lance Biechele. (MBP list)
