identify A. homolae from the northeastern United States, it probably also exists in eastern Canada associated with Atlantic boreal forests or in the mountains of western Massachusetts. In our genetic studies we are finding that there is a very large number of white or whitish species in sect. Vaginatae. The best thing we can say is that we will schedule this for sampling for DNA sequencing.

on the other specimen, I have learned. Nice little foray, many experts from several different clubs. Too bad I missed it, but it was really nice to see all the stuff on exhibit, and I didn’t have to get dirty or bitten by bugs.

I’m glad to know that, Britt

I was not sure whether you had found the somewhere else or not. I’ll add my photos to the observation, since they are so similar. I can create another obs. later if they turn out to be different.

Very excited to see this yesterday!

I was not actually on the foray where the specimens were collected. I was merely an observer at the fair and noticed some white amanitas sitting with destroying angels…that were definitely NOT destroying angels! I think I probably got everyone’s attention when I exclaimed “here’s the rare Amanita homolae!” (or something like it). Really exciting find and looks like a match for what we’re calling A homolae found on a foray a couple of years ago in northern WI. The specimens are partially dried already and will go on the dryer tonight. Although fairly delicate, there is a very prominent “old amanita” smell (not the same as Lepidellas but strong); gills are yellowing but don’t think they’ll turn orange. I don’t recall our “homolae” specimen from a couple years ever turning orange either. They were sent to RET. Once dried, these will be going to RET as well. I’ll await any further instructions, should any be coming forthwith.

I think that Yves Lamoureux’s A.albiceps” should also be considered.

At the NEMF at Bowdoin College last month, someone brought in a specimen that was very close to my original conception of homolae. The gills turned orange on drying. The gills were pale orangish white originally (when fresh), and the stem had an orangish white, matte surface. The above characters are included in my original field notes on the species I first called “homolae.”

Do you know if the gills of the mushroom featured in this observation turned orange on drying?

I’m not suggesting my provisional A.rasitabula” because that species has a more friable volva than is evident in these photographs.

Very best,

Rod

Thanks for your email regarding this observation and Britt’s similar collection.

DNA is showing that there are many white-capped taxa in the Vaginatae.

I think we are a long way from having an understanding of how many similar taxa there are.

Very best,

Rod
