Observation 171941: Amanita Pers.
When: 2014-07-27
No herbarium specimen

Notes: Multiple collections of these small Amanita’s around TESC today. Approx. 5 cm caps, canary yellow, small flocking from patches on cap margin, tight veil at base identical to A.pantherina’s I’ve collected here in summer and fall.

I know that most A.gemmatta and A.pantherina have been reported to be hybridized in this area(lower Puget Sound, WA) and as such are beginning to be separated into different Phylogenetic talons.

Note: strange pinkish tinge on upper stem- never encountered for either A.pantherina or A.gemmatta.
I am looking to Rod Tulloss for a possible suggestions.

Temp: low 80’s.

I had a longish thing written and managed to lose it by going back to check the image.

Your notes imply that you feel this material can be assigned to section Amanita. My only reservation is that it would be good to be able to see the stem base so that we can see there is no volval sac there.

I particularly like the second photo. The mushroom is really quite beautiful.

I think we need to get away from the old literature that speaks of hybridization in the PNW. Neither gemmata nor pantherina occurs in the region. In addition, while a small number of mushroom “mules” have been reported in recent years with supporting evidence, this is not the case in Amanita.

It seems very likely to me that you have a species of Amanita that may not be described. The name gemmata has been applied to a number of taxa in North America and, by all evidence, to more than one in the western coastal states of the U.S. Hence, careful collection with careful field notes and good photos followed by the drying of the collected material is going to be important.

Very best,

Rod
