Observation 146925: Agaricus augustus group
When: 2013-09-30
No herbarium specimen
0 Sequences

Notes:
Agarricus but what species? I was going to guess A. subrutilescens, but then noticed that cap flesh stains yellow near cuticle when cut. Both Arora and Trudell & Ammirati say that A. subrutilescens,is non-staining.
In duff (and possibly bark dust). Nearest tree was a spruce.
I do not have a mature specimen, so cannot tell real maximum sizes and other characters.

Cap

  • appears brown from a distance, but actually white, with abundant brown fibrils
  • max diameter 6.5 cm
  • mild almond odor and taste
  • flesh white, 1 cm thick
  • cap flesh stains yellow near cuticle when cut. See 3rd photo.

Gills

  • free
  • close
  • young gills off-white
  • 6mm

Stipe

  • shaggy white starting at partial veil downward for about 1/2 length of stipe, then brown fibrils
  • almost all the stipe was below the duff; only the cap was showing. See 2nd photo
  • 17.5 cm long
  • 2.5 cm thick
  • slightly bulbous base
  • almond taste
  • hollow
  • membranous partial veil still present in all specimens, so I cannot be certain what annulus will look like. But by how it’s attached to the stipe, I’m guessing it will be skirt-like
  • stipe does not stain on cutting or bruising
