Macbrideola confusa Nann. - Bremek. & Y. Yamam.

Macbrideola cf. confusa Nann.-Bremek. & Y. Yamam. [0, 1] Loc 12: On Prg barks, JRM123, 4 September 2008, (mc, pH = 7.9). The specimen agrees well with the original description of M. confusa as the capillitium arises along the entire length of columella dissipating into the main capillitium branches. Peridium early fugaceous but with a well-defined collar at the base of sporotheca. Capillitium rigid, anastomosed slightly toward the base of sporotheca, mostly spiny free ends. Spores globose, 9.5–10.5 diam., verrucose, violaceous brown. Mapimí specimen differs from M. confusa in the spore size, 7–8.5 diam., in the original description, and in the rather lax capillitium. If confirmed, this species would be the first record for the Neotropics (Lado & Wrigley de Basanta 2008).
