Observation 97322: Melanoleuca Pat.
When: 2012-06-14
No herbarium specimen

Notes: Cap: 2.2-2.5 inches wide (5-6cm), white to very light buff, some wrinkling (from dehydration?); stem 2 inches tall (5cm), white with some yellowing near cap, slightly wider at cap than base, dead grass or dried grass adherring to base of stipe; gills: close to crowded, white to a faint blueish tint where cap broken, flesh white or pale flesh-colored; spore print white (see halo of spores on grass).

My initial reaction was Melanoleuca, perhaps in the evanosa grouping, based on Arora in Mushrooms Demystified. The grass adherring to the base of the stipe is reminiscent of Marasmius oreades, but the cap is the wrong color. Also, to my nose Marasmius oreades is a richer, more complex aroma than this, which smells remarkably like Agaricus bisporus.
