Observation 67677: Amanita spreta (Peck) Sacc.
When: 2011-05-14
No herbarium specimen

Notes: Habitat:
Growing in someone’s front lawn, from soil.
( I will have to go back and see what kind of tree was in the front yard.)

4.2-12cm broad, umbonate to nearly plane, brown, smooth, one with white “warts”, striate margin (1.3-1.8cm), some striations were forked

Free, close, white

8.4-17.2cm long, (forgot to measure width), white to cream, with gray “scabers”, and with a gray “skirt-like” partial veil,

I believe there was a cup surrounding the base but cannot say for sure because I was in a hurry and failed to dig them up.
The guy (who owns the property) was mowing his grass and told me to hurry before he got to them.

The gray partial veil…

I think you are probably correct in assuming that there was a short volval sac at the base of the stems (hope you can find one of these for confirmation). A large brown species of section Caesareae with relatively short marginal striation (even at maturity), brownish or gray-brown cap (infrequently nearly white, at least in early development), and a partial veil that becomes gray —> Amanita spreta…or something very close to it that has no name (I should always add that, I guess).

Some information on A. spreta can be found here:


Very best,
