Observation 25969: Amanita citrina (Schaeff.) Pers.

When: 2009-09-24

Collection location: Luzerne Co., Pennsylvania, USA [Click for map]

Who: Dave in NE PA

Specimen available

Notes:
Marginate bulb easily peeled away from the stalk, giving the appearance of a thick volval sac. Spores amyloid. I did not notice any lavender patches on the cap, and the weather during the previous few days was dry, so I don’t think it’s lavendula.

The pale cap is (sometimes?) an indicator of citrina f. lavendula. The spores of lavendula are smaller than those of citrina proper.

Compare spore measurements for bulbosa var. citrina and citrina f. lavendula on the relevant species pages of the Amanita Studies site.
