Observation 4174: Amanita amerirubescens Tulloss nom. prov.
When: 2004-07-16
No herbarium specimen

Notes: Found during the NAMA 2004 Foray in Ashville. As Rod Tulloss states, this is what eastern US authors have been calling A. rubescens. Apparently the true European A. rubescens has not been found in North America.

Yellow volval warts in early development a frequent character of the eastern US “rubescens”

The yellowish tint of the volva (especially near the cap margin, which was longest protected from sunlight) is often seen (especially in buttons) of the eastern US taxon called “A. rubescens”. This suggests a possible relationship
with A. flavorubens G. F. Atk. and A. rubescens var. alba Coker.
The European taxon is provided with a brief description on a species page of the Amanita Studies site (here).

Widely used (and misapplied) European names are also illustrated on the regional checklist and picturebook for the central Atlantic coastal states.
