August 26 ’07 – Lot 1

6 unidentified Agaricus?20070826130448_pict0003.jpg20070826130510_pict0004.jpg20070826130538_pict0005.jpg20070826130610_pict0007.jpg20070826130631_pict0008.jpg

Lot of 6 mushrooms found growing in mulch under cedars. The bases were infested with termites (which I found rather odd).

Cap on the largest specimen was 5 inches across. White with what appear to be very small warts (UPDATE: Was just dirt from transport.). Small smattering of light brown here and there. Slightly inrolled margin.

Gills are a pleasant light brown to slightly pinkish brown. Crowded and short, free from stem. Youngest specimen had gray-buff gills and partial veil.

Stem was about 4-5 inches long, white, very prominent floppy ring. Very slightly bulbous at the bottom. Some infested with termites.

Spores dark chocolate brown.

UPDATE: Upon visual comparison of both macro features (cogwheeling on the ring, slight yellow-staining on the cap in pic 5) and spores, this appears to be a specimen of Agaricus arvensis or Agaricus macrosporus.
