Amanita arenicola O. K. Miller & Lodge

Material studied. MEXICO - Quintana Roo • J. I. de la Fuente 427 ( ITCV); Chetumal; 18°31′N, 088°18′W; alt. 8 m; 14 Oct. 2018 .

Habit and habitat. Scattered under Coccoloba uvifera in coastal vegetation.

Identification. This species can be recognized by the grey pileus with white patches that are the remains of the volva, white and free lamellulae, a whitish pileus sometimes with conspicuous white scales on the base, the small saccate volva, which sometimes remains underground, and the ellipsoid basidiospores of 8–10 × 6–8 µm. Our specimen from Quintana Roo agrees with the description provided by Miller et al. (2000), but it presents slightly shorter spores. Amanita agluttinata (Berk. & M.A. Curtis) Lloyd is a similar species but differs by the presence of a ring on the stipe ( Pegler 1983).
