sarcinatim septatis, constrictus ad septatis, 21–30 μm diam., parietus glabrus.

Colonies amphigenous, mostly epiphyllous, thin to dense, spreading, up to 3mm in diameter. Hyphae straight to flexuous, pale brown, branching irregular at acute to wide angles, loosely reticulate, cells 12–20 × 4–6 μm. Appressoria scattered, alternate, unilateral, ovate to mostly globose, entire, 8–10 × 6–8 μm. Conidiophores produced lateral to the hyphae, simple, micronematous, 6–8 μm long; conidiogenous cells terminal, intercalary, monoblastic, integrated, determinate, cylindrical. Conidia solitary, dry, simple, subspherical to oval, 2–10-celled, brown to charcoal black, muriform, sarcinately septate, constricted at the septa, 21–30 μm in diameter, wall smooth.

This is the first species of schiffnerulaceous fungus infected the members of the family Rhizophoraceae ( Hosagoudar 2003, 2011).

Etyomology: Based on the host genus.
