Anamorph: not known.
Teleomorph: ascostromata 100-120 µm diam., scattered or gregarious, epigenous or hypogenous, superficial. occasionally abundant on the detritus-rich portion above the leaf sheath, brown, globose to doliiform, with a rather variable fringe of dark brown, unbranched or ± irregularly branched setae. Setae 20-40 (-55) µm in length, thick-walled and smooth to slightly torulose, tapering to a slightly rounded or ± acute tip. Peridiurn composed of 3-5 layers of slightly flattened cells, cell walls of the outer 2-3 layers slightly thickened, (yellow-) brown, individual cells 4-8 x 2.5-4 µmin size, cell walls of the inner layers thin, hyaline. Interascal tissue of pseudoparaphyses 1.5-2 µm diam., apparently not always present; short hyaline periphyses lining the ostiolar canal. Asci (45-) 50-70 (-75) x (10-) 12-14 (-I5) µm, ± cylindrical to fusiform-cylindrical, almost sessile, the apex attenuated and rounded with an inconspicuous apical cap, possibly with rostrate dehiscence, 8-spored. Ascospores arranged in a fascicle, (40-) 55-65 (-70) x 2.5-3 µm, filiform-cylindrical, flexuous, the ends rounded, often coiled in the ascus, hyaline, with (10-) 12-14 (-15) inconspicuous septa, smooth, with small guttules, without an epispore or gelatinous sheath or appendages.
Not formally assessed. There are not many records of this species in GB&I (or indeed worldwide), but the fruit-bodies are small and can easily be overlooked.
Distinguished from other Taphrophila species primarily by the flexuous, narrowly cylindrical ascospores.
On dead leaves and culms of Ammophila arenaria and Calamagrostis epigejos, presumably a saprotroph.
Scattered throughout Great Britain; currently recorded from VC1 W Cornwall (Scilly Is), VC3 S Devon, VC4 N Devon, VC28 W Norfolk, VC45 Pembrokeshire, VC52 Anglesey and VC110 OuterHebrides (St Kilda).
