Stilbella-like anamorph on attached twigs of Sambucus nigra and Prunus padus. Sometimes in association with pyrenos, but not strictly.
Individual synnemata sometimes coalescing into larger orangeish formless mass. Ornamenting cells on stipe absent. Branching simple, conidiogenesis simple, apical. Conidia not exceeding 6x2um.

synnema tapered upwards, apex sterile, with lateral loose hyphae, conidia dry, not catenate. The shear number of condia suggests this is phialidic or anellidic but it isn't easy to see. Conidia length=3.4–4.0µm (µ=3.7, σ=0.2), width=2.2–2.5µm (µ=2.4, σ=0.1), Q=1.5–1.7µm (µ=1.6, σ=0.1), n=7

Light pink mold grew around an old specimen of Sclerencoelia pruinosa (on Populus bark).

on a piece of rotten wood in very wet (normally submerged) habitat.

Several individuals, superficially resembling miniature Lasiosphaeria ovina. Sporodochia pale gray, less than 0.5mm in width, scattered, conidial mass surrounded by an arachnoid net of small thin, dichotomously branched pale to brown hyphae. Conidiogenous cells containing many relatively long denticle, often in quick succession on the conidiogenous cell. Conidiogenous cells are hyaline

Conidia are aseptate, smooth, without appendages or visible sheets, somewhat allantoid and hyaline, they measure 6.5 - 9.5 X 2-2.5 µm.

Because of the arachnoid net surrounding the conidial mass and the conidia that are produced on denticles, the genus neta is the likely. Amongst the species, N. lignicola is easily reached using Castañeda and Heredia key (Mycotaxon 76: 132). N. tropicalis is also similar but have much more allantoid conidia.

also compare with N. patuxentica as seen here : https://www.inaturalist.org/observations/94171469
