Observation 205240: Agaricus augustus Fr.
When: 2015-05-29
No herbarium specimen

Notes: Found growing along a busy roadside, in cut grass in the shade of a large conifer (possibly a larch, did not appear to be a local tree species). Small cluster of about 7 mushrooms.
A very notable thing is the mushroom has an unpleasant odor that reminds me of gasoline or some sort of fuel. There were flies hanging out on it and I noticed a number of maggots on the mushroom.
Cap is very large, about 9-10 inches wide. Cap is dry, scaly, and pale yellow-beige. Flesh of cap turns yellow when rubbed. Gills are free from stalk and are pink to brown.
Stalk very thick and solid, about 2 inches wide where it meets the cap, broadening slightly at the root. No volva. Thin, hanging white veil, with some veil present on edges of cap. Stem above veil is smooth and violet-brown colored, stem below veil is scaly and pale yellow-beige like cap.

Smell the cut stem

This looks like Agaricus augustus to me, but it should smell of almonds rather than gasoline. I wonder if it may have absorbed some auto-funk from being near a roadway. I’d try cutting or crushing a bit of the stem and see if you can get a whiff of almond extract through the gasoline smell. Everything else you described besides the smell smacks of ‘the prince’.
