Observation 137909: Amanita “sp-T32” Tulloss cryptonom. temp.
When: 2013-06-09
0 Sequences

Single specimen growing in mixed woods in the Turkey Creek Unit.
Cap 3.9 cm across with 2-3mm striations.
Stem 7.5 cm long with rather thin and fragile annulus.
Stem seemed to stain yellowish-brown when handled.
Spores white and not amyloid.
Spores ~ 9.2-13.0 X 5.3-7.6 microns, ellipsoid to elongate.
Q(ave) = 1.73. Q(range) = 1.51-2.13.
Spores were relatively variable in size so my Q values(based on only 14 readings) need to be looked at as ball-park numbers.

Another undesirable single specimen, so my ID is very tentative.

I got your email concerning this collection.

I’d make sure that a sample for genetic study got into the hands of Santiago Sanchez ASAP.

Very best,


Hello, Ron. This is a cool one.

This could be what Amanita sp-T32 looks like before it ages. The description on WAO of that species has very similar spores to those you describe for your material, but is based on older material that might have had longer striation on the cap margin due to environmental factors like drying.

The spores are a very close match as I said; and the range of spore shape extending into range of “cylindric” spores is very unusual for species of sect. Caesareae.

This would be a great piece of material for Santiago Sanchez to sequence for his study of the roaming of the genes of the Caesareae.

I’d love to see the material when you get a chance.

Very best,
