black, raised on host tissue, solitary, scattered, superficial, pulvinate, globose, rough, multiloculate, containing 4–6 locules, with individual papillate ostioles, cells of ascostromata brown-walled textura angularis. Locules 320–370 × 450–500 μm. Peridium of locules two-layered, up to 30–40 μm wide, outer layer composed of small heavily pigmented thick-walled cells of textura angularis, inner layer HSP inhibitor composed of hyaline thin-walled cells of textura angularis. Pseudoparaphyses hyphae-like, septate, numerous. Asci 138–185 × 32–36 μm \( \left( \overline x = 164 \times 35\,\upmu \mathrmm,\mathrmn = 15 \right) \), 8–spored, bitunicate, fissitunicate, cylindro–clavate,

with a long pedicel and wide shallow ocular chamber. Ascospores 9–12 × 3–6 μm \( \left( \overline x = 11 \times 5\,\upmu \mathrmm,\mathrmn = 30 \right) \), biseriate, hyaline to light brown, obovoid to ellipsoidal, flattened in one plane, with rounded ends, smooth–walled. Asexual state not established. Material examined: PARAGUAY, Villa Rica; Mbocaiaté, on leaves of Prunus sclerocarpa, 15 January 1882, B. Balansa No 3443 (LPS 281, holotype) Notes: The type specimen examined is relatively immature and it was very Cyclin-dependent kinase 3 hard to find asci and ascospores. This is a very distinct fungus and should be recollected and epitypified. The smaller spores in Fig. 8 were not observed on the type specimen. Barriopsis A.J.L. Phillips, A. Alves & Crous, Persoonia 21: 39 (2008) MycoBank: MB511712 Saprobic on dead twigs. Ascostromata brown to black, immersed, aggregated or in clusters, scattered, erumpent at maturity, discoid to pulvinate or learn more hemisphaerical, discrete, multiloculate. Ostiole central. Pseudoparaphyses hyphae-like, septate, embedded in gelatinous matrix. Asci 8–spored, bitunicate, clavate to sub-clavate, short stalked.
