BRIEF DESCRIPTION: The cap of Amanita tijbodensis is 60 - 130 mm wide, convex, white, slightly viscid, without volval remnants or sometimes covered with a few large, white patches.  The flesh is 4 - 8 mm thick over the stem and rapidly thins near the margin.

The gills are free, pale, close to cartridge buff, 5 - 10 mm broad at the midpoint.  Short gills are not described.

The stem is 100 - 200 × 12 - 25 mm, white, solid at first, becoming hollow in age, barely narrowing upward, with a bulbous base, 25 - 45 mm wide.  The ring disappears with age. The stem is decorated with small appressed scales, rapidly becoming smooth.  The bulb bares a limbate volva which is not otherwise distinguished from the bulb.

The spores measure 6 - 9 µm in diameter and will probably not prove to be perfectly spherical and are amyloid.  Clamps are probably absent at base of basidia.

This species was originally described from Java and is not well understood.  As a white species of section Phalloideae, it should be expected to be POISONOUS.
