Upreti and Pant 1993). Multigene phylogenetic studies<br />

indicated that Arthopyrenia salicis, a typical species of<br />

Arthopyrenia, is located within <strong>Pleosporales</strong> in close<br />

proximity to bambusicolous species in the genus Roussoella,<br />

with its familial status remaining undetermined (Del Prado et<br />

al. 2006; Schochetal.2009; Zhang et al. 2009a).<br />

Ascocratera is a monotypic obligate marine fungus and<br />

is characterized by conical, crater-like, erumpent to<br />

superficial and carbonaceous ascomata, a depressed<br />

ostiole, a thick peridium, trabeculate pseudoparaphyses,<br />

bitunicate, fissitunicate and cylindrical asci, and ellipsoidal,<br />

hyaline, 1-septate (3-septate when senescent) ascospores<br />

surrounded by a sheath (Kohlmeyer 1986).<br />

Ascocratera was reported to be one of the most common<br />

marine fungi of the upper intertidal zone of dead<br />

mangrove roots, trunks and branches (Kohlmeyer 1986).<br />

Based on a multigene phylogenetic analysis, Ascocratera<br />

nested within the clade of Aigialaceae (Schoch et al.<br />

2009; Suetrong et al. 2009).<br />

Type species: Atradidymella muscivora M.L. Davey &<br />

Currah, Am. J. Bot. 96: 1283 (2009).<br />

Atradidymella was introduced as a pleosporalean genus<br />

parasitic on boreal bryophytes, and is characterized by
