I was excited to find this little guy as it’s the first Amanita I had seen all season (other than the ubiquitous A. xanthocephala). I did collect it but I only found this single specimen and unfortunately the maggots got to it before me.
The inner surface of the limbate volva appeared powdery but I did not notice this on the stipe. The cap was also coated in this light grey powder which could be wiped away to reveal a darker grey surface. There were flat, membranous veil remnants on the cap (more toward the centre) which appeared dark grey but the dirt made it hard to tell the colour. The base of the stipe was bulbous, but only slightly. The lamellae were adnexed, some forking outwards and appeared off-white or a very light grey.
I managed to get a few spores under the microscope (see last two photos). I don’t have Melzer’s but tried some Lugol’s and observed a brownish hemiamyloid? reaction. I don’t know whether that’s helpful or not.
At the moment, a wet period of the eastern U.S. summer is swamping us with material. Is there really no herbarium specimen? I see a bulbous stem with a limbate volva and gray powder on the stem in the area which suggests that the gray powder is the remains of an internal limb of the volva. This is a very curious thing. And is their gray powdery or friable material on the cap also? It seems to me that there might be some. This suggests a combination of characters associated with sect. Amidella and sect. Lepidella and make me think of Amanita grisea except that the watercolor deposited in Kew with the type collection would suggest (at least it did to me) that the stipe is bulbless.
Tim I’d like to know your response to these thoughts. After all, you (or someone) held the beast in his/her hand per your photograph. :-)
