Technical description (t.b.d.)

BRIEF DESCRIPTION: The cap of A. antillana is up to 90 mm wide, olive-brown, convex, subumbonate, and subviscid, with a margin that bears rather short striations. The volva is absent from the cap.

The gills are free, white, and very broad.

The stem is 90 x 13 mm, narrowing upward, decorated with fibrils, and exannulate. The flesh is hollow. The volva may disappear from the stem at maturity.

The spores measure (8.4-) 9.8 - 13.3 (-14.3) x (7.1-) 7.7 - 10.5 (-11.9) µm and are inamyloid and subglobose to broadly ellipsoid (occasionally ellipsoid). Clamps are absent at bases of basidia.

Somewhat similar taxa can be found listed on the A. ceciliae (Berk. & Broome) Bas page; however, the ellipsoid shape of the spores of A. antillana alone segregates it from most of these taxa.

This species is known from the islands of the Antilles. It was originally described from Trinidad, and probably conspecific material has been collected on Martinique.
