BRIEF DESCRIPTION: The cap of A. flammeola is 60 - 90 mm wide, narrowly rounded-conic at first, expanding to applanate with decurved margin, umbonate, margin striate (10 - 15% of the radius); it is saffron yellow, straw yellow at margin, becoming paler with age. The flesh is fairly thick, firm, and white. The volva is absent.

The gills are free, crowded, and saffron yellow or paler. The short gills are truncate, common, unevenly distributed, of at least three lengths.

The stem is 60 - 150 x 5 - 20 mm, narrowing upward, and exannulate. The volva is subcylindric, sac-like, and up to 60 mm tall; it is white, membranous, with a thick exterior surface layer appearing to be delaminated.

The spores measure (8.6-) 10.5 - 13.3 (-15.4) x (5.7-) 6.3 - 7.7 (-9.0) µm and are ellipsoid to elongate (rarely cylindric) and inamyloid. Clamps are were not observed at bases of basidia.

The species was originally described from Zambia and is known from central Africa.

The flame colored cap of this species becomes quite pale with age and exposure. For comparison to a small group of tropical taxa apparently related to A. flammeola, see <A. dunicola Guzmán and A. sampajensis A. V. Sathe & S. M. Kulk. -- R. E. Tulloss
