Observation 196643: Clitocybe candida Bres.
When: 2015-01-18
No herbarium specimen

Notes: Cluster of large white mushrooms in a circle about 30 feet in diameter with about 20 specimens in the area. Under old Oaks but Short-leaf pine also near.

Cap: largest specimen was 7 inches across. Most mature were 4-5 inches across. Top of cap was white with tan coloring toward the center. Cap had thick white flesh. Surface of cap peeled easily. Largest caps were split open. One over mature cap showed a pinkish color on the top edges and brownish streaks.
Young specimens were convex with edges turning under. Largest flattened out but edges still turned down. ( see photos ) Cap was dry.

Gills: white to off-white ( I thought they might be slightly pink but I was in heavy shade which may have given the pink color cast), close. Joined to stipe, just starting to run down stipe. Easily pulled away from stipe and easily broke away from cap.

Stipe – thick, solid flesh but appeared to be long strings of soft fiber bundles.
The base of the all the stipes twisted as turned horizontal as they entered the ground. All were rooted with white mycellium at the base.

Staining: I did not see any darkening or staining due to being cut or broken.
KOH: negative

Smell – very mild.

Spores – Print is white.

Spore size – (appear yellow in photos due to Sudan Stain)
