Very interesting Amanita species, thanks for documenting!

I’m digging around…

I’m going over all the related literature to try to get a picture of which descriptions (original or otherwise) actually match Roy’s photo. I’m beginning to suspect that there are at least two competing concepts of A. ochrophylla.

For example, Reid’s water color and the color illustration from Grgurinovic (originally, I think from a Cleland publication) don’t seem to match Bas’ study of the species which included the holotype. Anyway, you’ll hear more from me later. I’m afraid it’s going to be a rather long post.

reference (Grgurinovic’s tome on mushrooms of Australia) (forgot to mention that), I opted for ochrophylloides over ochrophylla because the morphology of the stipe base illustrated for the latter is not marginate. I think I have a Kodachrome somewhere of a non-marginate “ochrophylla” from N Qld that I will have to find and scan. Thanks Rod!!

Maybe there are two options here?

I love these lepidellas from Australia. Roy’s photo makes the the hair on the back of my neck (where there still is some) stand up. Whew…

I know A. ochrophylla and A. ochrophylloides only from the original descriptions, from Reid’s 1980 monograph, from the water color painting of the former by Reid in that monograph, and from Bas’ description of the former in his 1969 thesis/monograph. I don’t have personal experience with the taxa fresh or dried.

Simplified versions of the descriptions of the two taxa appear on the Amanita studies site.

It seems to me that A. ochrophylla is a rather good match to Roy’s super photo. The two are (apparently) closely created and belong to A. subsect. Gymnopodae Bas.

If we go back to observation 12278 (I just did), I think Roy’s image is much more of a match to A. ochrophylla’s description than the mushroom in 12278. Notice the very distinct upper membranous layer which is present on the patches on the cap in Roy’s photograph. The mushroom in Roy’s photograph conforms to the literature for ochrophylla much better than the form of the warts in 12278. In the latter case, I made a serious mistake of confusing what species was illustrated in Reid’s water color (looks like I can’t do taxes and mycology at the same time).

I’m not going to propose a different name because it’s after midnight in NJ, and I’ll probably just make another mistake at this hour.
