Pleurophragmium aquaticum R. F. Castañeda, Heredia & R. M. Arias , Mycotaxon 101: 92. 2007.

Typus.

MEXICO • Veracruz, “ Los Tuxtlas ”; on decaying wood submerged in a stream; 19 May 2002; R. M. Arias & J. Y. C. Elizondo ( holotype XAL CB 743 , isotype: MUCL 45625 ) .

Notes.

Conidia formed on holoblastic-denticulate conidiogenous cells are fusiform to clavate, occasionally navicular, and often sub-umbonate at the apex. They are brown, becoming pale brown to subhyaline toward the ends and around the septa. By their shape and pigmentation, the conidia closely resemble those of P. miniumbonatum ( Heredia et al. 2007) . Pleurophragmium aquaticum also resembles P. fusiforme in having fusiform, pigmented conidia with paler ends, but the latter species differs in having narrower and uniformly pale brown conidia except the ends (without the paler bands at the septa).
