Saprobic on fallen decaying twigs of Bruguiera cylindrica. Asexual morph: Mycelium composed of vegetative hyphae, on half-strength seawater MEA, hyaline, 2.5–3.5 μm wide, septate, branched, smooth, partly compacted to form hyphal strands. Conidiophores hyaline, simple or branched, elongated, erect or flexuous, up to 45 μm long, sometimes ending with sterile cells. Conidiogenous cells enteroblastic, phialidic with periclinical wall thickening, discrete or adelophialides, with discrete phialides subcylindrical to elongate-ampulliform and constricted base, single or in conidiophores,10–40 × 1–3 μm; adelophialides cylindrical, 2.5–8 × 1.5–3 μm; collarettes distinct,1–2.5 μm long, 1.5–2 μm wide, with 1.5 μm wide opening. Conidia 3.5–4.5 × 2.0–3.0 μm (x̅ = 4 × 2.5 μm, n = 20), hyaline, aseptate, cylindrical with a tapered and truncate base, smooth-wall sometimes held together in droplets. Sexual morph: Undetermined.

Comments:

NOTES: Jattae is predominantly a terrestrial asexual genus with some 28 species, of which two are known from marine habitats J. bruguierae and J. mucronata (Dayarathne et al. 2017, Abdel–Wahab et al. Bot. Mar. 2017). Réblová et al. (2015), based on combined LSU, SSU, ITS, RPB2 and β–tubulin genes, places the genus Jattaea in the Calosphaeriales. Jattaea mucronata, introduced in Abdel–Wahab et al. (2017), is the first documentation of a sexual morph of Jattaea and associated with a marine habitat, while J. bruguierae is the first record of an asexual morph from mangroves.
