Index Fungorum number: IF 121020; Facesoffungi number: FoF11910 , Fig. 1
Description:
Saprobic on host. Sexual morph: Apothecia large, up to 1500 μm diam., dark olivaceous to black, single to solitary, or scattered, mostly superficial, slightly immersed in host tissue, flattened, circular to subcircular, discoid, semicircular in section, edge entire, slightly convex at the top, raised from the base. Excipulum about 30–60 μm thick at base, parenchymatous, with thin-walled, deeply pigmented, subangular to globose cells. Hymenium 90–120 μm thick. Paraphyses 2.5–3.0 μm cylindric, septate, occasionally branched, sometimes longer than the asci. Asci 55−95 × 5.2−5.9 µm (x̄ = 78 × 5.7 µm, n = 20), 8-spored, bitunicate, fissitunicate, narrowly cylindric-clavate, rounded apex with an indistinct ocular chamber. Ascospores 8−10 × 4−5.2 µm (x̄ = 8.8 × 4.7 µm, n = 10), uniseriate, elliptic or elliptic-clavate, slightly narrowed near the middle, two-guttulate, pale olive brown to deep brown. Asexual morph: Unknown.

Importance and distribution
Catinella comprises three species known on Fagus sp. (Fagaceae), Pinus resinosa (Pinaceae), Populus sp. (Salicaceae), Salix sp. (Salicaceae) and Ulmus sp. (Ulmaceae). Catinella is reported from Asia (China, Indonesia), Europe (Sweden, Ukraine and United Kingdom) and North America (Canada).
