There is increasing motivation for drying without too much delay.

Drying relatively quickly not only kills bugs and larvae; it also protects cell structure for anatomical examination and protects DNA.

I always appreciate your efforts. There will be another cokeri and/or subcokeri. No worries.

Very best,


Sorry about that

I waited too long to get it in the dryer, and the bugs got to it first.

Thank you, Patrick.

The reddish stain on the bulb is a marker for subcokeri. Coker said he never saw “pink staining” that his northern correspondents reported on what they thought was cokeri. Oh, well. Can you check the Q value of the spores?

Very best,

seem loosely attached to the cap, this might be the true A. cokeri. It is more common in the southern U.S. than is A. subcokeri.

Very best,
