Technical description (t.b.d.)

BRIEF DESCRIPTION: Very little is known about this species.  This description is largely based on that of Reid (1980).

The cap of Amanita curta is 50 to 65 mm wide, convex at first, then flattened, ochraceous-white, even, and smooth.  The margin is often appendiculate.

The gills are free, remote, rather distant, narrow, and white.

The stem is short (no more than 25 mm long), solid, bulbous, brick-red, and smooth.  No annulus is present.  A limbate, membranous volva encircles the margin of the stipe's bulb.  The bottom of the bulb is said to bear what I take to be bundles of hyphae with the appearance of "rootlets."

The spores measure (9.0-) 10.0 - 14.5 x 5.0 - 6.0 µm according to Reid and are elongate to cylindric (infrequently ellipsoid, infrequently bacilliform) and strongly amyloid.  RET's measurement of spores from the type in Kew are 10.8 - 14.5 (-17.7) x (5.0-) 5.2 - 7.5 (-8.4) µm.

This species was originally described from the state of Victoria, Australia; Reid knew it only from the type locality.  From the current state of the type (covered with sand), one can assume that it occurred in sandy soil.  I am not certain that this species is properly assigned to section Amidella.  The base of the stipe should be investigated to see if the volva is limbate or saccate and whether a true bulb is present.  If the latter were the case, then placement in sect. Lepidella would be a possibility. -- R. E. Tulloss
