BRIEF DESCRIPTION: The cap of A. perpasta is 40 - 170 mm wide, convex to plane, fleshy, whitish to pallid cream or pale brown, dry, with a nonsulcate, ragged-appendiculate margin.  The flesh is white, probably turning somewhat yellowish, dry, and firm.  The cap is densely covered with adnate, conical to truncately conical warts, or polygonal patches with conical, sometimes recurved appendages; towards the margin, the cap is covered with smaller, more or less erect scales.  The tips of warts and scales are subferruginous-brown.

The gills are rather crowded, free, thick, broad, cream-white, with a flocculose edge.  The short gills are rounded, obliquely truncate to attenuate.

The stem is 50 - 140 x 30 - 55 mm, clavate to broadly ventricose, solid, firm, whitish to pallid, and annulate.  Brownish granules to flat scales are present below the ring, smaller scales in closer circles form towards the base; coarse, truncate warts are present on the underside of the ring.

According to Bas (1969), the spores measure 7 - 8.5 (-10.5) x 6.5 - 8 (-9.5) µm and are globose to subglobose (rarely broadly ellipsoid) and amyloid.  Clamps are not found at bases of basidia.

Originally described from tropical forest in Singapore and Malaya.  The species is also reported from Japan.

This species was placed by Bas in his stirps Perpasta along with A. hongoi Bas.
