Materials examined. COLOMBIA • Magdalena, Santa Marta, locality of Minca, Cerro Kennedy ; 11°06.33′N, 074°03.42′W; 2520 m a.s.l.; 31 Jul. 2015, K. Ramírez Roncallo leg.; KRR 13; CBUMAG:LIC:178 .

Identification. Marginal phyllidia or squamules present; margins rugged with white macules. These

features, together with the presence of pruine, give the thallus a fragile and brittle appearance ( Díaz-Escandón 2017).

Ecology and distribution. Polyblastidium fragilissimum has been recorded in the departments of Boyacá, Cauca, Norte de Santander, Tolima, and Valle del Cauca, in the foothills and Andean forests from 800 to 3000 m a.s.l., on bark and mosses ( Díaz-Escandón 2017). In SNSM it was found in the Andean forest, at 2520 m a.s.l., on bark.
