Recognized by sight: /holds Amanita in front of giant spotlight, sweeps Gotham skies with its silhouette.
61% (2)
Recognized by sight: In particular I would suggest the Indian and east Asian species of Amanita subsection Vittadiniae as one set of possibilities. Notice the yellow staining of the stem and gills. This might indicate that the mushroom is “suffering” from the “yellowing syndrome” that is discussed here:
I’m not suggesting subsolitaria as a diagnosis…I’m only referring to this page for a discussion of the “yellowing syndrome.” It is also a possibility that the yellow staining is genetically determined by the mushroom and is not the product of some “infection.”
The list of currently accepted names in the above subsection can be found here (with links to the descriptions of most of them):
Such species are very often not mycorrhizal with plants according to a hypothesis going back at least to the thesis of C. Bas (1969) that was recently affirmed in a paper by Wolfe et al. earlier this year (2012).

I took a look at the other observation that you suggested. It would be very unusual for a species of subsection Vittadiniae to maintain warts in the center of the cap, but have a moist (possibly gelatinized) cap surface for the outer half of the radius. At least for the species studied in detail (30-40), the universal veil is intimately connected with the upper flesh of the cap without a well-defined pileipellis separating the two tissues. Hence, the gelatinization of a pileipellis allowing warts to be washed off probably does not happen until the fruiting body is well past maturity…essentially senile.

With regard to the question of exuding moisture, the species of subsection Vittadiniae are very hygroscopic (whether alive or dried), and exudation of liquid has been noticed in at least one species probably related to A. albofloccosa, namely, A. nauseosa. A specimen of A. nauseosa growing in a greenhouse in Edinburgh, Scotland was described as exuding droplets from its gills when it was found.

Think this could be an observation of the same? From my bleak memory, it did have a rather memorable smell, much like these. Also, when cut does this species have a watery discharge from the stipe?

G, I’m very glad to hear from you on this observation.

Please do keep me up to date on what you find as you go back over your collections.

Very best,

I checked the description, and from what I remember, these seem to match the description and check all boxes of basic morphology there. I would totally agree with the distinctive smell, which I remember to be especially nauseating.

Glad to hear its some use, although this was a while ago. I am at the moment organising and cataloging my own collection, which has been in disregard unfortunately for some time. I will def. get back, I may actually have tissue or print material, Im not sure of its condition though.

Definitely keep an eye out, I may have found more of these sometime later on in my collecting as well!


I found one possibility of an ID for this mushroom. [edit]

Amanita albofloccosa was described from Maharastra state. The original description suggests the type collection exhibited the “yellowing syndrome.” The known information concerning albofloccosa is available here:


It would be very helpful if the spores of this material could be examined and the bases of basidia could be checked for clamp connections.

G, please do not hesitate to contact me with questions. If you can dry this material (please query if you wish), it would be very enlightening to examine it. Also, the original collection of this species is pretty much destroyed by mold. A new collection placed (at least in part) in a temperature and humidity controlled herbarium would be very important for improving knowledge of this species. It looks like you may have created a very important record with this posting.
