Panaeolus cyanescens Sacc. View in CoL

Material studied. MEXICO - Quintana Roo • J.I. de la Fuente and Aragón 310 ( ITCV); Chetumal; 18°31′N, 088°18′W; alt. 8 m; 27 Sep. 2017 GoogleMaps .

Habitat and habit. Scattered on humus on secondary vegetation.

Identification. This species can be recognized by the whitish pileus, greyish lamellae, bluish reaction when cut, and subglobose, dark brown basidiospores of 9–12 × 6–9 µm. The material agrees with the description provided by Pegler (1983). It differs from P. antillarum (Fr.) Dennis by the bluish reaction (negative in P. antillarum ) the size of the basidioma and the lack of metuloid cystidia (absent in P. antillarum ).
