Observation 24503: Amanita constricta Thiers & Ammirati
When: 2009-07-21
No herbarium specimen

Notes: Found this fella in the Adirondacks of NY in mixed coniferous forest including hemlock. The base looked funny to me – something I haven’t seen here on Amanita in the midwest. I consulted with Jay Justice who verifies this to likely be in the vaginatae section, most resembling A. constricta with two exceptions: (1) veil/volva is said to turn reddish-brown. This one didn’t. However Rod Tulloss site notes that he has never observed them turning reddish-brown either. (2) this was found in the Northeast, all other descriptions of A. constricta are described from California. Is there an east or northeast version of A. constricta or is this some other species?

The volval sac

seems too well defined to be one of the “constricted” Amanitas. With these types the volva typically collapses onto the stem base thus creating the strangulated effect.

… Just checked Rod’s site and there is one pic of A. constricta with well defined sac. But he lists this as a western NA species.
