Observation 6938: Amanita muscaria group
When: 2007-01-02
Herbarium specimen reported

Notes: Oddly shaped cap and gray universal veil. I already sent you half of this collection, Rod, last year! Any determination? I have been seeing a number of amanitas with a gray universal veil recently; could it be environmentally caused??!

Used references: Jenkins’ type study of A. pantherinoides.
Based on microscopic features: Compared spores with those of type of A. pantherinoides and two other collections of that species—not a good match. Clamps locally common on bases of basidia and otherwise satisfying the conditions for the muscarioid group. The spores are a best match for A. muscaria subsp. flavivolvata, but they also suggest spores from three specimens studied by Geml which appear to be undescribed taxa related to the muscaria clade. An interesting collection.

thanks for sharing your latest findings. I had no working species concept for pantherinoides, couldn’t argue one way or the other.
we saw them in the same area for two years running….I will surely check again come next winter.

Well, it’s not pantherinoides…

I removed my old comments. I’ve found they just went down the wrong track and then compounded the error.

Over the last two days I’ve been looking at all my notes on Amanita pantherina var. pantherinoides because of recent queries I’ve received about that taxon. Among the notes were my notes on dried material representing this observation. I have also recently looked at some characters of pantherinoides on the type collection. First of all, this material from Pt. Reyes is nowhere near the pantherina group because it has locally common clamp connections and satisfies the criteria for being a muscarioid taxon. It could be an unusually colored muscaria subsp. flavivolvata or an undescribed species. So I’m going to propose the name Amanita muscaria group.

I’m going to send samples to Joe Geml for DNA testing.

Very best,
