Macbrideola cf. oblonga Pando & Lado View in CoL [1, 1]

Loc 12: On Prg barks, JRM127, 19 November 2008, (mc, pH = 7.6). Loc 18: On Ag s leaves, AET11683 (MA-Fungi 88109 sub Lado18830), 27 October 2007.

Sporocarps dispersed, stalked, up to 0.45 mm in total height. Stalk conical, short, 0.16 mm height. Peridium evanescent but with a well-defined collar. Sporotheca oblong, 0.3 × 0.26 mm. Columella almost reaches apex of the sporotheca, where it branches into two or three main branches. Capillitium anastomosed, forming a superficial net, with numerous spiny free ends, which does not correspond with the original description of M. oblonga that has free blunt ends, slightly swollen or club shaped ( Pando & Lado 1988).

Most of the characters agree with the description of M. oblonga , except by the smaller spores in Mapimí specimens, 7.9–9.9 diam., versus (9–)10–11 µm reported by Pando & Lado (1988). This species has been reported from Colorado Plateau ( Novozhilov et al. 2003) and Tehuacán-Cuicatlán Valley ( Estrada-Torres et al. 2009).
