Spores minutely roughened, with a large apical germ pore.

Spore measurements:

12.1 [13.5 ; 14.5] 15.9 × 7.5 [8.5 ; 9.2] 10.2 µm
Q = 1.4 [1.5 ; 1.6] 1.8 ; N = 16 ; C = 95%
Me = 14 × 8.8 µm ; Qe = 1.6

Sorry about that Amanita persicina

I didn’t mean to delete your comment. Some of these collections have resembled yours. Also, how small were the pins for your P. olivaceus? These Pans, whatever they are, are so small my lens can’t get accurate focus. Is it possible to get that comment back?

Alan said he thinks they are P. olivaceus and I’ll be sending samples to him for microsopy. If I had an adapter I could try a shot at it myself. So close and yet so far …

Also, morning temps were 36 F here, so I think that’s cool weather for GA.
