Macrocybe titans (H.E. Bigelow & Kimbr.) Pegler, Lodge & Nakasone View in CoL

Material studied. MEXICO - Quintana Roo • J.I. de la Fuente and Quintal Palomo 299 ( ITCV); Kohunlich; 18°25′N, 088°47′W; alt. 120 m; 12 Sep. 2017 GoogleMaps .

Habit and habitat. Caespitose on humus in evergreen tropical forest.

Identification. This species can be identified by the big size of its basidiomata, the caespitose habit, the crowded white lamellae, and the thick stipe with brown scales. Microscopically it is distinguished by the globose spores, 5.9–8.3 × 4.3–5.9 µm, the ventricose cheilocystidia, the lack of pleurocystidia, and the presence of clamp-connections. Our material agrees with the description provided by Guzmán and Piepenbring (2011) but presents smaller cystidia.
