When: 2012-08-28
Herbarium specimen reported

Notes: Very large species. Notice some pinkish tints to the stem and some reddish staining on the base. No smell recorded.

Updated with spore data:

[27,1,1] (10.0) 10.1 – 11.4 (11.6) x (6.0) 6.2 – 7.4 (7.5)
Q = 1.44 – 1.73
L’ = 10.7
W’ = 6.8
Q’ = 1.58

Some additional spore data:
[44,1,1] (9.8) 10.0 – 11.7 (11.8) x (6.2) 6.3 – 7.4 (7.5)
Q = 1.45 – 1.78
L’ = 10.9
W’ = 6.9
Q’ = 1.60

Updated:

Dried specimen cap a cap width of 4.5 inches and a height of 8". When fresh it was quite large. The cap was likely in the 7-8 inch range across and the specimen was likely 11-12" tall.

The second species referenced is subcokeri. The brief tab of the A. cokeri page has been rewritten to be more specific. Thanks for pointing out the undesirable vagueness.

To try an get an independent smell….

I just had two ladies give it a whiff, and both say the dried specimen is like foot odor. It has been with many mushrooms for the last day and a half, but out of the dehydrator for 6 hours or so. Be that what it may.

if subcokeri was the species you were talking about with the pinkish tints on the corkeri page, or if it was another species.

I’m sure that I’m just duplicating your efforts, but…

I just plotted sporographs for cokeri, subcokeri, and your spore measurements. Your spores are small for both species.

Pinkish tints definitely develop in subcokeri; and subcokeri has a distinctive odor (especially after being wrapped in was paper for a few hours and then opened under one’s nose). Amanita cokeri doesn’t have an odor until it gets oldish … and then the odor is rather unpleasant.

I think that __subcokeri__’s range extends farther south than has been previously reported; and I think cokeri is rarer than previously reported. We get an awaful lot of subcokeri in the New Jersey pine barrens; and I have only seen one collection of cokeri in the barrens in over 30 years.

Very best,

Rod

RET, on your cokeri page you mention….

a species that has pink to reddish staining in the northeast. Think this could be it?

Updated spore data.
