=Dematiopleospora luzulae Wanas., Camporesi, E.B.G. Jones & K.D. Hyde, Fungal Diversity 75: 103 (2015)

Etymology: Name reflects the host genus Luzula from which the species was collected (From Ariyawansa et al. 2015).

Holotype: MFLU 15-1503.

Saprobic on dead stem of Luzula sp. Sexual morph: Ascomata 140–160 μm high, 175–200 μm diam. (x̄ = 148.4 × 184.5 μm, n = 10), immersed, solitary, scattered, globose, brown to dark brown, coriaceous, fusing with the host tissue, ostiolate. Ostiole 25–40 μm high, 30– 50 μm diam. (x̄ = 29.5 × 36.2 μm, n = 5), black, smooth, upper covering of ostiole, comprising short, light brown setae-like structures. Peridium 10–20 μm wide at the base, 10–15 μm wide at the sides, comprising 3–4 cell layers of thin-walled, brown cells of textura angularis, inwardly lighter. Hamathecium comprising numerous, 2–3 μm (n = 30) wide, filamentous, branched, septate, pseudoparaphyses. Asci 70–80 × 15–20 μm (x̄ = 76.4 × 18.1 μm, n = 40), 8-spored, bitunicate, fissitunicate, cylindric-clavate, short pedicellate, rounded and thick-walled at the apex, with an ocular chamber. Ascospores 15–20 × 7–10 μm (x̄ = 19.3 × 8.6 μm, n = 50), overlapping biseriate, initially hyaline, becoming brown at maturity, ellipsoidal to oval, some curved, muriform with 4–6 transverse septate and 3–4 vertical septa, strongly constricted at the central septa, the two cells rows above the central septum wider, weakly constricted at the other septa, conical and narrowly rounded at the ends, surrounded by a thick, hyaline, mucilaginous sheath. Asexual morph: Undetermined.

Culture characteristics: Colonies on PDA reaching 30–35 mm diam. in 21 days, olivaceous-grey, spreading with moderate aerial mycelium, with smooth, even, margins; reverse iron-grey.

Material examined: ITALY, Trento Province, Mezzana, Marilleva 1400, on dead stem of Luzula sp. (Juncaceae), 1 August 2013, E. Camporesi (MFLU 15-1503, holotype); extype living culture, MFLUCC 14-0932.

Notes: In this study we synonymize Dematiopleospora luzulae (Ariyawansa et al. 2015) as Italica luzulae and introduce it as the type species of Italica.
