Observation 22965: Amanita sect. Amanita

When: 2005-12-26

Collection location: Bolinas Ridge, Marin Co., California, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

These were found in the same area as http://mushroomobserver.org/22893?search_seq=571208 and are very likely the same species. I have not named them Amanita aprica because in checking my notes and e-mail correspondence with Rod Tulloss in Sept of 2007, he felt that these are likely not A. aprica because the warts all appear to all have rather distinct cleft lines separating them. He also mentioned that his field ID at the SOMA Camp of the above noted observation could quite possibly be incorrect. I’ll defer to Rod as to what to call them in the various posted Observations.
I will later post another observation from Jan of 2005 from the same spot of a group of small specimens that are not quite as orange and the warts a little less distinct but most likely the same species/variety.

hard to get a size sense.

I agree Ron.

We have ourselves something different here, and the opportunity to nail a description while it’s out and about.

These appear to be cospecific with a couple

of recent Observations(MO 29729 and MO 29672). They look much like this group as well as two other Observations of mine from the same area; MO 22966 and MO 22893. At first I was also calling them Amanita aprica but they seem to have somewhat different characteristics, besides not growing in the Spring in the Sierras.

I’d definitely put this in the “I dunno” category.


I’m glad that you addended these Marin aprica sightings, Ron…

if I recall, Rod had done an in-hand (on plate?) ID at SOMA camp at the time, so no scope verification of the specimen. and it really didn’t have the typical ingrown warts of aprica. but who was I to argue with our Amanita Man on a mushroom that I had never seen before!

I have also collected some odd gemmata/aprica-like amanitas in Marin that really don’t fit neatly into either category. The mystery continues!
