Mucilopilus mexicanus (Guzmán) Rolfe Material studied. MEXICO - Quintana Roo • J. I. de la Fuente 29 (ITCV); Hermenegildo Galeana; 18°10′N, 089°14′W; alt. 229 m; 29 Aug. 2014. Habit and habitat. Solitary or scattered in lowland forest and pine savanna, sometimes associated with Coccoloba or Gymnoponium species. Identification. This species can be recognized by the greyish pileus, slightly tomentose when young, viscid when aged, the pinkish pores which become grey when aged, the viscid stipe, the fusoid spores 8.1–12.2 × 4.1– 5.9 µm, and the clavate cystidia. The specimen agrees with the description provided by Guzmán (1974). This species resembles Fistulinella gloeocarpa Pegler in having the basidioma viscid, but it differs from that species by the spore size and the ampullaceous cystidia which has a long slender neck (Pegler 1983).
