cap |
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. |
gills |
The gills are rather crowded, free, thick, broad, cream-white, with a flocculose edge. The short gills are rounded, obliquely truncate to attenuate. |
stem |
The stem is 50 - 140 × 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. |
spores |
According to Bas (1969), the spores measure 7 - 8.5 (-10.5) × 6.5 - 8 (-9.5) µm and are globose to subglobose (rarely broadly ellipsoid) and amyloid. Clamps are not found at bases of basidia. |
discussion |
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. |

intro |
The following text may make multiple use of each data field. The field may contain magenta text presenting data from a type study and/or revision of other original material cited in the protolog of the present taxon. Macroscopic descriptions in magenta are a combination of data from the protolog and additional observations made on the exiccata during revision of the cited original material. The same field may also contain black text, which is data from a revision of the present taxon (including non-type material and/or material not cited in the protolog). Paragraphs of black text will be labeled if further subdivision of this text is appropriate. Olive text indicates a specimen that has not been thoroughly examined (for example, for microscopic details) and marks other places in the text where data is missing or uncertain. The following material is derived from the protolog of the present taxon and (Bas 1969). | ||||||||

Each spore data set is intended to comprise a set of measurements from a single specimen made by a single observer; and explanations prepared for this site talk about specimen-observer pairs associated with each data set. Combining more data into a single data set is non-optimal because it obscures observer differences (which may be valuable for instructional purposes, for example) and may obscure instances in which a single collection inadvertently contains a mixture of taxa.
