Observation 191151: Amanita chrysoblema G.F. Atk.
When: 2014-12-01
No herbarium specimen

Notes: -This specimen was associated with the soil. It was found growing in the middle of a grass field with nothing around it.
-It was growing gregariously because there were many forms of it around. Some of the caps were cup-shaped while the mature forms were flat.
-The diameter of a mature pileus was measured to be about 5.5 cm.
-The surface of the pileas was shiny, somewhat “sticky” (tacky), and granular because it looked like it had warts on the surface.
-The pileal shape was a plane.
-The pileas was of a pearly, white/beige color.
-The flesh was white in color.
-The centrally located stipe was also pearly white.
-The stipe was measured to be around 6.8 mm in length, and about 0.6 mm in width.
-The shape of the stipe was hollow and somewhat clavate.
-The base of the stipe was assumably a myceliel pad.
-The stipe was “sticky” (tacky), shiny, and appressed squamulose, and there was no changes when it was damaged with a knife.
-The beige-colored gills were attached to the collar, and the margins were even.
-It appeared to have two lamellae tiers that were regular in pattern.
-There was no gill latex to be detected, but an upturned annulus and circumsessile volva were detected.
-From the spore print, it was a light tan.

Many life stages of this specimen was collected. At an immature form, the pileus was convex. However, the bigger forms were flat and planer.
