Observation 8674: Amanita Pers.
When: 2008-08-04
Herbarium specimen reported

Notes: Jay Justice has it.

Curious critter, doesn’t fit easily anywhere: strong smell of chloride of lime, but with a deeper component, too;
pulverolent universal veil/warts, gray and yellow; tiny superior annulus, pulverulent, gray edged with yellow; gray pulverulence on stipe (easily removed); whole fruit body yellows (yellowing disease?); context yellows when cut. NO pink cast to gills, doesn’t turn bright orange
when bruised. Just another darned unidentifiable lepidella, but a quite distinctive one.

taxa known to “get” the yellowing syndrome

Maybe it would be worthwhile to gather together the names of taxa that we find that may be exhibiting the yellowing syndrome. At first I saw it almost exclusively on Amanita subsolitaria (Murrill) Murrill. Bas’ provisionally named A. crassifolia was thought by him to be (possibly) a yellow specimen of A. subsolitaria. I’m now convinced that this was the case.

In the last few years, I have seen “yellowing syndrome” on A. cinereoconia G. F. Atk. (in the Smokies, TN side). Bas proposed a yellowing variety of the latter, which is probably not a good taxon, but is probably based on material with the aforementioned syndrome. With the gray on the stem and on some warts, A. cinereoconia might be a candidate for an ID in the present case.

Bas also proposed a yellowing variety of A. rhoadsii (Murrill) Murrill. Hence, we must suspect that it may exhibit the yellowing syndrome.

There are yellowing amanitas reported from east Asia and Madgascar. I’m sure that I have missed some that I’ve seen myself. My memory is not what it once was.

Very best,
