Observation 111234: Amanita sect. Phalloideae (Fr.) Singer

When: 2012-09-24

Collection location: Moon Lake Park, Pennsylvania, USA [Click for map]

Who: Dave W (Dave W)

Specimen available

These are the darkest-colored ones I have yet found… of what I presume to be the same species.

Still working on tree IDs for this obs.

I have found patches of this type mushroom in several different areas of Moon Lake Park, with tree species variable. But in each case there is at least one oak in the vicinity. I think they may all be Scarlet Oaks. Still working on the tree IDs.

Some spores finally dropped :-)

We didn’t see anything RE KOH on the sheets.

I do want to say how much we appreciated getting those field note forms with lots of detail. The amount the forms were appreciated is very, very much. :)


I don’t recall checking the KOH reaction…

for any of the material from this patch of amanitas. But I think I may have included a completed “amanita form” for at least one collection made at this site. So KOH info may have been recorded on one of these sheets.

Hi, David.

This material has been accessioned in our herbarium. Thank you very much for sending it. The stocky, robust stature suggests Amanita sp-O01 as a possibility. Did you get KOH reaction data?

Very best,
