Ascospores (29.5-)31–34 × (13-)15–15.5 μm \( \left( 1 \right) \), biseriate, brown to dark brown, aseptate, ellipsoid-oval, inequilateral, slightly curved, widest in the median to supramedian, ends rounded, light brown in the centre, smooth or verrucose, without a gelatinous sheath. Conidiomata stromatic, pycnidial, dark brown to black, superficial, mostly multilocular, individual or aggregated, thick-walled, ostiolate. Ostiole central, circular, non-papillate. Paraphyses hyaline, usually aseptate, sometimes becoming up to 2–3–septate, not constricted at the septa, thin-walled,

tip rounded, occasionally branched. Conidiogenous cells 7–12 × 3–5 μm, holoblastic, hyaline, cylindrical, thin-walled, smooth, proliferating at the same level, with visible periclinal www.selleckchem.com/products/mln-4924.html thickening. Conidia (20-)23–25(−28) × (11-)12–13(−16) μm, initially hyaline, aseptate and thick-walled becoming dark brown and septate with irregular longitudinal striations (asexual morph description

follows Stevens 1926; Abdollahzadeh et al. 2009). Material examined: CUBA, Herradura, on twigs of Citrus sp., 15 January 1925, N. E. Stevens (BPI599052, holotype). Notes: The asexual morph was not observed in the type and the ex-type culture which was isolated more than 80 years ago and has lost its ability to sporulate. The second species Barriopsis iraniana was introduced Y-27632 2HCl with only an asexual morph as no sexual stage was formed in culture. The morphological characters (the conidia are striate at an early stage of development and the striations are clearly visible in young, hyaline conidia) confirmed that the asexual morph of Barriopsis is linked to a Lasiodiplodia-like morph. Barriopsis fusca differs from B. iraniana by its distinctly smaller conidia (23–25 × 12–13 μm vs. 24–30 × 14–18 μm) (Abdollahzadeh et al. 2009; Stevens 1926). Botryobambusa R. Phookamsak, J.K.

Saprobic on dead bamboo. Ascostromata dark brown to black, immersed under epidermis to erumpent, gregarious, visible as minute black dots or papilla on the host tissue, multiloculate, locules individual globose to subglobose or fused, coriaceous, vertical to the host surface, with a central ostiole. Neck central, papillate, periphysate. Asci 8–spored, bitunicate, fissitunicate, clavate to cylindro-clavate, pedicellate, with well-developed ocular chamber. Ascospores hyaline, velvety, aseptate, ellipsoidal to obovoid, smooth and thick-walled, surrounded by a mucilaginous sheath. Pycnidia developing in stromatic clusters, fused, multiloculate, individually globose to subglobose.
