  • intro Very little is known about this species.  This description is largely based on the original description and that of Reid (1980).
    cap The cap of Amanita curta is 50 to 65 mm wide, convex at first, then flattened, ochraceous-white, even, and smooth.  The margin was appendiculate in the only known collection.
    gills The gills are free, rather distant, narrow, and white.
    stem The stem is short (no more than 25 mm long), solid, bulbous, brick-red (or terracotta), and smooth.  The ring in the one known specimen was left in pieces on the edge of the cap.  An apparently membranous volva encircles the margin of the stem's bulb.  The bottom of the bulb is said to bear bundles of hyphae with the appearance of "rootlets."
    odor/taste Odor and taste were not recorded for this species.
    spores The spores of A. curta 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 spore data are 10.8 - 14.5 (-17.7) x (5.0-) 5.2 - 7.5 (-8.4) µm.
    discussion 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
