Taxonomy and Systematics
Species: Agrocybe vervacti (Fries 1821) Singer 1936
Notes on taxonomy: Agrocybe vervacti was originally classified as Agaricus vervacti in 1821, and in 1936 it was reclassified as Agrocybe vervacti by Singer. The Agrocybe genus contains approximately 100 species.
I keyed my specimen with Barron's "Mushrooms of Northeast North America: Midwest to New England" and confirmed with other sources.
Agrocybe vervacti caps are hemispherical to broadly convex. The smooth and dry caps range from 2-4 cm in diameter and range in color from ochre to orange-brown. The thin and well formed gills are attached. These relatively tightly packed gills are brown. The dry stalks can grow as up to 7 cm tall and a maximum of 8 mm wide and are uniform throughout. The stalks vary from beige to pale orange-brown and are mildly rough textured and striated with darker fibers. Agrocybe vervacti spore prints are brown. Agrocybe vervacti fruit on the ground in grassy areas. Agrocybe vervacti typically fruit during the summer months.
The edibility of Agrocybe vervacti is unknown.
Campus distribution and habitat
My Agrocybe vervacti specimens were found scattered about in great numbers in the tree and grassy area around the tree house at 1:00 pm on Monday, 12 September, 2011.
