Observation 176243: Amanita aureosylvatica Tulloss, Rodrig.-Cayc., Morales-Tor. & Ovrebo nom. prov.
When: 2012-04-29
Herbarium specimen reported

Notes: Collected in the back yard of the Champibol Mushroom Farm and home of the Daniela Camacho and family. The grounds contained a variety of planned and unplanned fungi, of which this was by far the most striking. Odor recorded as fresh-farinaceous changing to that of Hygrophorus pudorinus (which I hate).

Host: unknown. nearby tree spp. include “Pajarillo” (?) and Guava (Psidium sp.)

Habitat: semihumid tropical forest and savannah, 550 meters a.s.l., some urban development and disturbance (Jorochito is a town of ~4000).

Collectors: D. Newman, I. Cuba, E. Melgarejo, D. Camacho & S. Poquiviqui,

the question was not what are the micro differences, which were clearly stated on your excellent website. The question was are there obvious macro differences between the two species, such that one might actually be able to identify this in a provisional way through a mere photo or in hand, which is often all that we have to work with on MO.

And Danny, I get that we had little to work with with that first cap only photo. But when I referred to your experience with a very similar yellow amanita in Bolivia, I wondered why you might not have proposed it as a “could be.” My could be’s of Pholiota, Cyptotrama, etc., was because those were the only things that I have ever seen that even vaguely resembled that cryptic fb! But I wasn’t proving the ID, just throwing up possibles. In fact, your proposal of Amanita only came after the two known yellow tropical saprobic amanitas were proposed. We coulda used a little help right out of the gate! A could be is hardly a slam dunk, and way mo’ useful than an Agaricales proposal. Just sayin’.

…is segregated by falling into a different stirps in Bas’ (1969) system; among other things, A. aureosylvatica has clamp connections throughout the fruiting body (especially notable on the bases of basidia). The African species does not.

One day, I will not be around to answer questions. Better to read the website now and learn how to use it to answer questions.

was this specimen ever examined microscopically?

no

what are the macro differences between the two yellow Saproamanitas, Rod?

I will let Rod address that in detail, but FWIW, A. aureofloccosa was described from the Congo and may be exclusively Paleotropical.

Who has the fb?

Either HC.UCBSP or USZ.UAGRM, can’t remember… but someone will know. good luck getting it out of Bolivia.

And hey Danny, if you actually held this distinctive yellow Saproamanita in your hand

I did

why didn’t you propose Amanita for our recent “Agaricomycete” obsie? As if!!!

Because that observation has no notes, no photographs of anything but the cap from above, and no corresponding specimen. once I noticed the white, mature gills on the blurry background FB I proposed Amanita sp. Going any further on such a data-deficient observation is wishful thinking.

Nice backyard pop-up serendipitous mushroom!

I seem to remember taking much more extensive notes on this, yet all that’s in the typed copy the girls sent me of the notebook we used is what’s just been added to the ‘Notes’ section. awaiting their reply to see if any information is missing from that document. otherwise, that’s all the data we’ve got. there are some unimpressive studio images of the same fruiting body shot against millimeter graph paper, which would allow for some retroactive measurements to be made, for whatever that’s worth…

Very interesting posting, Danny.

I’m looking forward to your notes.

Very best,
