Apex with or without papilla and with a pore-like ostiole. Peridium 2-layered. Hamathecium of dense, long cellular pseudoparaphyses, septate, embedded in mucilage. Asci bitunicate, fissitunicate, cylindrical to clavate, with a short, furcate pedicel. Ascospores ellipsoid, hyaline at first, turning brown at maturity, 1-septate, strongly JNK-IN-8 constricted at the septum. Anamorphs reported for genus: none. Literature: Yuan 1994. Type species Barria piceae Z.Q. Yuan, Mycotaxon 51: 314 (1994). (Fig. 10) Fig. 10 Barria piceae (from NY 92003, isotype). a Ascoma on the host surface. Note the wide opening ostiole. b Section of the partial peridium with two types

of cells. c, d Asci with ocular chambers and short pedicels. e, f Ellipsoid ascospores which are turning brown with thin sheath around them. Scale bars: a = 0.5 mm, b = 50 μm, c, d = 20 μm, e, f = 10 μm Ascomata 240–370 μm high × 200–320 μm diam., solitary, scattered, immersed, globose, subglobose, coriaceous, apex with or without papilla and with a pore-like click here ostiole (Fig. 10a). Peridium 20–35 μm thick, comprising two cell types, the outer cells comprising 3–4 layers of brown pseudoparenchymatous cells, cells 4–5 μm

diam., cell wall 2–3 μm thick, inner cells comprising 3–4 layers of pale brown compressed RGFP966 mouse cells, cells 2 × 16 μm diam., cell wall 0.5–1.5 μm thick (Fig. 10b). Hamathecium of dense, long cellular pseudoparaphyses, 2–3 μm broad, septate. Asci 135–200(−220) × 14–20 μm (\( \barx = 156 \times 16.6\mu m \), n = 10), 8-spored, bitunicate, fissitunicate, cylindrical to clavate, with a short, furcate pedicel, up to 22 μm long, with a large ocular chamber (ca. 4 μm wide × 3 μm high) (Fig. 10c and d). Ascospores 19–21.5 × 10–12 μm (\( \barx = 20.4 \times 11\mu m \), n = 10), uniseriate to partially overlapping, ellipsoid, hyaline or greenish with numerous small guttules at first and olive green to smoky

brown at maturity, 1-septate, strongly constricted at the septum, foveolate, surrounded with sheath (Fig. 10e and f). Anamorph: none reported. Material examined: CHINA, Xinjiang Province, Uygur, Dapagliflozin Urumqi, Tianshan Mountain, on needles of Picea schrenkiana, 1 Jul. 1992, Z.Q. Yuan (NY 92003, isotype). Notes Morphology Barria was established by Yuan (1994) as a monotypic genus represented by B. piceae according to its “two-celled, pigmented ascospores, pseudoparenchymatous peridium and narrowly cellular pseudoparaphyses” thus differing in its combination of characters from all of the morphologically related dothideomycetous genera, such as Didymosphaeria, Didymopleella or Stegasphaeria. The taxon was considered to belong in Phaeosphaeriaceae. Ascomata and colour or shape of ascospores, however, readily distinguish it from other 1-septate Phaeosphaeriaceae genera, i.e. Didymella, Lautitia and Metameris (Yuan 1994). Barria piceae causes blight of spruce needles. Phylogenetic study None.
