Index Fungorum, Facesoffungi, MycoBank, GenBank.

Classification: Incertae sedis, Incertae sedis, Incertae sedis, Incertae sedis, Pezizomycotina, Ascomycota, Fungi

Saprobic on the host plant in terrestrial habitat. Sexual morph: undetermined. Asexual morph: Conidiomata dark brown to black, stromatic, pycnidial, amphigenous, solitary to gregarious or confluent, immersed to erumpent, rounded or elongate, or sometimes concave in surface view, broadly conical in sectional view, unilocular, and locule often irregularly divided and convoluted, glabrous, thick-walled. Ostiole absent, opening in a circular to oval channel in the apical wall. Conidiomatal wall composed of thick-walled, pale brown to hyaline cells of textura angularis. Conidiophores formed from the innermost layers of conidiomata, hyaline, subcylindrical, swollen and septate at base, smooth-walled. Conidiogenous cells hyaline, enteroblastic, annelidic, cylindrical to lageniform, or dolliform, discrete or integrated, indeterminate, smooth-walled, with 1–2 percurrent proliferations. Conidia hyaline, fusiform, unicellular, thick- and smooth-walled, guttulate, bearing mucoid appendages at both ends.

Notes: The monotypic genus Zelandiocoela was introduced by Nag Raj (1993) to accommodate a species segregated from Allantophomopsis. He discussed the differences between Zelandiocoela and several morphologically similar genera. The significant difference between Zelandiocoela and Allantophomopsis refers to the fact that the conidium appendages in Allantophomopsis are of type C, while the appendages in Zelandiocoela are of type H (Nag Raj 1993). Zelandiocoela is a monotypic genus. There is no molecular data available for Zelandiocoela. To clarify the taxonomy of Zelandiocoela and closely related genera, fresh collections are needed.

Type species:  Zelandiocoela ambigua (Nag Raj & W.B. Kendr.) Nag Raj, Coelomycetous Anamorphs with Appendage-bearing Conidia: 991 (1993).

Other accepted species: Species Fungorum – search Zelandiocoela.
