intro

The following is based on Miller (1992).

cap

The cap of Amanita kalamundi is (18-) 31 - 57 mm wide, broadly convex to nearly planar in age, dry, brown, with a nonstriate margin.  The volval remnants are present as scattered, irregular, filmy patches of orange volval material reduced to orange fibrils at the cap margin.  The flesh is firm and white.

gills

The gills are adnate, close to subdistant, white at first, cream in age.  Short gills are said to be in a single tier.

stem

The stem is 65 - 90 × 6 - 9 mm, cylindric, nearly lacking in decoration, and buff with orange over the basal bulb or entirely orange below the ring and then with the orange surface minutely granular.  The ring is superior, weakly membranous, skirt-like, orange, sometimes disappearing at maturity, sometimes leaving minute fibrils along the cap margin.  The flesh is white (except in the bulb where it may be yellow-tinted) or yellow throughout.

odor/taste

The odor is not distinctive.

spores

The spores measure 8.4 - 11 (-12) × (5-) 6.5 - 8.4 µm and are broadly ellipsoid to ellipsoid to elongate and amyloid.  Clamps are absent at bases of basidia.

discussion

Originally described from the state of Western Australia in association with Eucalyptus and Agonis.

I agree with Miller that this species' placement in section Validae is tentative. His description seems to imply that the margin of the cap is lightly appendiculate. This and the weakness of the annulus would be unusual characters for a species of section Validae.  However, given our current understanding of Amanita, there is no other obvious placement for it.—R. E. Tulloss
