Stilbella fimetaria
Anamorph: conidiomata absent. Synnemata solitary or in large clusters, 250–750 µm tall, capitate, the stipe 50–150 µm diam., cylindrical or slightly tapering, white to cream, sometimes pale yellow or pale brown at the base. Head 100–400 (–500) µm diam., globose, hemispherical, turbinate or discoid, pink to yellow or orange, robust, ± smooth, unbranched, rarely proliferating to form a second head above the first. Hyphae of stipe mostly 2-3 µm diam., thin-walled, smooth or rarely sparsely verrucose. Conidiophores once or twice branched, the branches 12.5–18 x 1.5– 2 µm, closely appressed to the main axis. Conidiogenous cells in terminal whorls of 3–6, (15–) 20–34 µm long, 1–1.5 µm diam., ± cylindrical to slightly tapering, straight or curved, lateral and terminal, proliferating percurrently, with inconspicuous collarettes and periclinal thickening. Conidia (3–) 3.5–5 (– 6) x (1.5–) 2–3 µm, ellipsoidal to cylindric-ellipsoidal, occasionally slightly obovoid, hyaline, aseptate, with slightly thickened walls, smooth, without a gelatinous sheath or perispore.
Teleomorph: not known.
Not formally assessed. The species is reasonably common and widespread, and is probably under-recorded.
On dung of a wide variety of mammals, especially that of rabbit but also reported on that of cow, dog, hare, sheep etc. Occasionally found on rotten vegetation, which has perhaps been in contact with excrement.
Widely distributed from the south coast of England to Orkney, also from north and South Wales and ROI.
