Observation 209405: Amanita sect. Lepidella sensu Bas
When: 2015-07-09
No herbarium specimen

Notes: Big chlorine Lepidella, rectagular warts, close gills narrowly attached, flocculent material on margin, below ring zone, turnip shaped bulb somewhat rooting. This somewhat resembles Jenkins concept of Amanita marginata but that is speculation on my part. I’m hoping Rod will see this one

the description for magniradix fits pretty well. the spores are somewhat cylindrical about twice as long as wide, I did not measure them. The chlorine smell was distinct from the beginning. This was on a sandy eroded bank on the side of a road bordered by oak/beech/birch woods. renee had suggested subsolitaria but there were no crossveins or split gills. I don’t think I’ve collected this one before.

If you got the whole bulb, then I’d suggest Amanita rhopalopus. If the bottom of the bulb broke off, I’d suggest A.magniradix.” They are both species in Bas’ stirps Rhopalopus. Details and differences can be found here:

Also in the same group is A. smithiana. These should all be expected to contain the non-protein amino acid that causes liver and kidney failuare in the case of smithiana.

Very best,

Rod
