Description

Conidiophores 200-283 μm long (x̅ = 346.2 μm, SD =21.3, n = 20), 6-10 μm wide (x̅ = 7.5 μm, SD = 1.8, n = 20), cylindrical. Conidiogenous cells 21-40 μm long (x̅ = 28.5 μm, SD = 5.6, n = 20), 5.4-6.5 μm wide wide (x̅ = 6 μm, SD = 0.36, n = 20), monophialidic, integrated, terminal, cylindrical-clavate, with flared collarette. Conidia 13-15 μm long (x̅ = 14 μm, SD = 0.79, n = 20), 12-14 μm wide (x̅ = 13.2 μm, SD = 0.84, n = 20), formed in chains, aseptate, turbinate-triangular, with three blunt protruding edges at the broader distal end, hyaline to subhyaline when young, greyish-brown at maturity, smooth-walled.

Notes

Chaetosphaeria catenulata was firstly reported on submerged wood on the side of Nujiang River, Yunnan Province ( Luo et al. 2019). Réblová et al. (2021) transferred it to Catenularia Grove as Catenularia catenulata . Morphologically, it is similar to C. cubensis Hol.-Jech, but the latter has smaller conidia (13-15 × 12-14 μm vs. 5.5-9 × 3.5-5.5 μm) ( Luo et al. 2019).
