Material studied. MEXICO - Quintana Roo • J.I. de la Fuente 210 ( ITCV); Hermenegildo Galeana; 18°10′N, 089°14′W; alt. 229 m; 25 jan 2016 GoogleMaps .

Habit and habitat. Scattered on humus under Gymnopodiumfloribundum and Coccolovadiversifolia in lowland forest.

Identification. This species can be identified by the greyish to cream pileus, slightly wrinkled when aged, the whitish lamellae which stain brown when touched, the peppery white latex, and the ovoid basidiospores 8–11 × 6–9 µm with small verrucae, not reticulated. Our material agrees with the descriptions provided by Pegler and Fiard (1979) and Pegler (1983). Lactifluus­caribaeus (Pegler) Verbeken has a similar pileus coloration, but it has a remarkably bad odour ( Pegler and Fiard 1979). Lactifluus­chiapanensis (Montoya, Bandala & Guzmán) De Crop also grows under G.­floribundum but has smaller spores (8–8.8 µm) (Montolla-Bello 1994).
