Basionym: Camarosporium caraganicola Phukhamsakda et al., Fungal Diversity 72: 156. 2015.

Saprobic on dead branches of Caragana frutex. Asexual morph: See Liu et al. (2015). Sexual morph: Ascomata 400–550 µm high, 450–500 µm diam (x̅ = 436.2 × 457.8 µm, n = 10), black, superficial to semi-immersed, confluent, gregarious, sometimes scattered beneath the host periderm or on decorticated wood, fully or partly erumpent, globose, rough or hairy, ostiolate. Ostiole central, short, slightly sunken, minute, inconspicuous on surface, smooth, with ostiolar canal filled with hyaline cells. Peridium 60–80 µm wide at the base, 50–70 µm wide in sides, comprising 8–10 layers, with outer layer heavily pigmented, thick-walled, comprising blackish to dark brown cells of textura angularis, cells towards inside lighter, with inner layer composed 3–4 layers, hyaline, flattened, thin-walled cells of textura angularis. Hamathecium comprising numerous, 2.5–3 µm (n = 40) wide, filamentous, branched, septate, pseudoparaphyses. Asci 150–190 × 10–15 µm (x̅ = 170.8 × 13.1 µm, n = 40), 8-spored, bitunicate, fissitunicate, cylindrical, short-pedicellate, rounded at apex with a minute ocular chamber. Ascospores 20–30 × 7–10 µm (x̅ = 24.9 × 8.7 µm, n = 50), overlapping uniseriate, muriform, mostly ellipsoidal, 3−5-transversely septate, with 2−4 vertical septa, constricted at middle septum, initially hyaline, becoming brown at maturity, slightly paler, conical and narrow at the ends, not surrounded by a mucilaginous sheath.

Colonies on PDA: Slow growing, reaching 2 cm diam after 4 wk at 16 °C, later with dense mycelium, circular, rough margin white at first, greenish grey after 6 wk, reverse greenish grey, flat on the surface, without aerial mycelium. Hyphae septate branched, hyaline, thin-walled.
