Technical description (t.b.d.) BRIEF DESCRIPTION: This description is taken from the original description of Bas (1978). The cap of A. coacta is 40 mm wide, umber in the center and pallid in marginal grooves, concave with or without a very slight umbo, with a sulcate-striate margin (extending to 50% of the radius). The volva is present as a few irregularly shaped, paler gray-brown felted, thin patches around the center of the cap. The gills are free, crowded, fairly broad, and white. The short gills are very scarce and truncate. The stem is 70 x 3 mm, tapering upward, without a bulb, exannulate, and white. The flesh is white and unchanging. The volva is up to 10 mm high at the base of the stem and felted-submembranous. The spores measure 8.5 - 10.0 x 6.5 - 7.5 µm, and are broadly ellipsoid to ellipsoid. Clamps are absent at the bases of basidia. This species was originally described from material collected in secondary rain forest (Manaus, Amazonas, Brazil) by Dr. Rolf Singer. -- R. E. Tulloss & L.
