Ostiole central, short, slightly sunken, minute and inconspicuous at the surface, smooth, ostiolar canal filled with brown to hyaline cells. Peridium 10–25 µm wide at the base, 30–40 µm wide in sides, comprising 4–5 layers of reddish-brown to brown, cells, lighter and flattened towards the inside, of thin-walled cells of textura angularis. Hamathecium comprising numerous, 2–3 µm (n = 40) wide, filamentous, branched, septate, pseudoparaphyses. Asci 60–90 × 14–17 µm (x ̅ = 75.9 × 15.4 µm, n = 40), 8-spored, bitunicate, fissitunicate, cylindrical-clavate to cylindrical, short pedicellate (8–12 µm long), apex rounded with a minute ocular chamber. Ascospores 12–16 × 6–8 µm (x ̅ = 14.9 × 7.2 µm, n = 50), overlapping biseriate, muriform, mostly ellipsoidal, with 3 transverse septa and one longitudinal septum, deeply constricted at the middle septum, slightly constricted at remaining septa, initially hyaline, becoming pale brown at maturity, upper part wider than lower part, slightly paler, rounded at both ends, conical at the lower end. Asexual morph: undetermined.

Pertinent Literature:
Neocamarosporium phragmitis is similar to N. lamiacearum in having globose ascomata with an apapillate ostiole, cylindrical-clavate asci and muriform, ellipsoidal, with 3-transversely septate, ascospores with one longitudinal septum, which are rounded at upper end and conical at lower end. However, N. lamiacearum has thin peridium and larger asci comparatively to N. phragmitis. A comparison of the 522 ITS (+5.8S) nucleotides reveals 32 (6.13%) differences that justify they are different taxa. Currently six Neocamarosporium species are known from marine habitats on a variety of hosts: 1. Salt marsh plants: Halimonie sp.: N. obiones (Jaap) Wanas. & K.D. Hyde, Studies in Mycology 87: 249 (2017) Salicornia sp.: N. salicorniicola Dayarathne, E.B.G. Jones & K.D. Hyde, Studies in Mycology 87: 250 (2017) 2. Tortoise shell: N. chersinae Crous, IMA Fungus 8 (1): 146 (2017) 3. Sediments in saline lake: N. jorjanensis Papizadeh, Wijayaw., Amoozegar, Shahzadeh Fazeli, & K.D. Hyde, Mycol. Progress 17(5): 672 (2018) N. persepolisi Papizadeh, Wijayaw., Amoozegar, Shahzadeh Fazeli, & K.D. Hyde, Mycol.
