Observation 69128: Amanita “sp-34” Tulloss crypt. temp.

When: 2011-06-13

Collection location: Luzerne Co., Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

Specimen available

This may be one of the types which has gone by the name Amanita russuloides. But I do not reference this name, as it currently seems to apply to a type which has a ring on the stipe (Kuo). Maybe the ones seen here did have a ring at one point in time? But I found no such evidence for this collection. Amanita Studies website mentions that some collections of a type called A. russuloides were ringless… at least at the point in time when they were collected. Awaiting spore drop.

On a lawn with oak.

Yup, I believe these to be…

the same as what we have been calling “sp 34.” This type seems to be quite common in grassy areas with oak.

The short stature and long striations and association with oak suggests….

Amanita sp-34.


These did initially bring to my mind

the possibility of being very small examples of A. crenulata, which often loses its ring. But, the small size and early occurrence seemed out of place. Also, it really seemed like the ones seen in the first two pics (initial collection) were completely ringless. In the newer collection (hopefully the pics came out okay) there are a few very fresh ones with caps not completely expanded and no sign of a ring or a partial veil. Also, the fresh newer ones show very fine, but prominent, marginal striations that I believe surpass the 10% to 20% typical for crenualta.

Hope to post more pics… maybe not until tomorrow… kinda busy today.

Are the striations just as long on less dehydrated specimens? It reminds me of Amanita crenulata.

I made another collection

of these yesterday, same oak tree on a dry sloped lawn. A few nice fresh ones. I think I can now say with confidence that this is a ringless species. Haven’t had a chance to view the pics yet.

Spores not amyloid.

Hope to post more pics within the next few days.
