Technical Description (t.b.d.)

BRIEF DESCRIPTION: Based on the original description of Murrill (1941) and type study by David T. Jenkins (1979).

The cap of Amanita subphalloides is 40 mm wide, convex to slightly depressed in the center, viscid, umbrinous with a very dark center, with a nonstriate margin except in age. The volval remnants are present as randomly distributed floccose patches. The flesh is thin, white, and odorless.

The gills are narrow, very close, white with a rosy tint.

The stem is 60 × 5 - 7 mm, solid, subcylindric, white, blushing where bruised", with a few floccose-membranous patches on the top of the bulb. The ring is large, fixed 20 mm from top. The bulb is small, white, globose. The volva is mostly carried up on the cap.

The spores measure 5.5 - 6.2 (7.4) × 5.5 - 7.0 (7.8) µm and are globose to subglobose and amyloid. Clamps are absent at base of basidia.

Originally described from Florida, USA under oak, solitary but relatively frequent in mid-summer (according to Murrill (1941)). 

Coker's comments suggest that the bulb reminded him of A. brunnescens G.F. Atk. It's unfortunate that Murrill did not say what color the stem turned when bruised. All things considered, it seems likely that he was correct in considering A. subphalloides to be similar to A. brunnescens. There seem to be one or two small taxa with color similar to that of A. brunnescens. The status of A. subphalloides is currently unknown. -- R. E. Tulloss
