| Description： |
Ascomata 1000-1500 μm wide, 850-1100 μm high, solitary, scattered, immersed in the leaves and petioles, lenticular, ostiolate, clypeate above the ostiolar region. Ostiole central, papillate, 87-125 μm wide. Peridium up to 17 μm thick is composed of elongated pseudoparenchymatous cells fusing with clypeus. Ostiole central, papillate, 85-125 μm wide. Paraphyses up to 2 μm wide, hyaline, filamentous, mucose, aseptate. Asci 62.5-90.0 × 7.5-10.0 μm, thin walled, unitunicate, short pedicellate, 8-spored. Ascospores 27.5-62.5 × 2.5-5.0 μm, guttulate, hyaline, fasciculate, slightly twisted and inflated at the ends and in the middle. | |||

| Note： |
Ophiodothella (Henn.) Höhn. comprises about 15 species with characteristically filiform ascospores which are fasciculate within the ascus (Höhnel,1910; Boyd, 1934; Batista, Powell & Peres, 1967). The taxonomy of the genus has not been investigated recently. Cannon (1991) indicated that the genus should be maintained pending more exact investigators regarding its relationship with Phyllachora. Paraphyses were deliquesce at maturity and more or less filiform ascospores which are fasciculate within asci are features common to Ophiodothella and not typical of Phyllachora. The fasciculate ascospores and deliquescent paraphyses refer this species to Ophiodothella. | |||
