Desmazierella acicola  

Anamorph: conidiomata absent. Conidiophores to 800 µm long, 8-12 µm thick above the often swollen base, hardly tapering, with verticillately arranged primary branches and secondary and tertiary branches also verticillate. Conidiogenous cells to 60 µm long, 3-5 µm thick at the base and 2-3 µm at the apex, proliferating sympodially. Conidia 4-6 x 2.5-3.5 µm, ellipsoidal, hyaline or pale brown, aseptate,  minutely verrucose.
Teleomorph: ascomata apothecia, to 5mm diam, sessile or shortstalked, flat to cupulate, setose on the outer surface, situated on a brown subiculum and sometimes in association with its anamorph. Hymenium buff, dotted with dark brown setae and appearing tomentose; outside clothed with dark brown, straight hair. Medullary excipulum of intertwined hyphae. Ectal excipulum of light to dark brown angular cells, sometimes thick-walled, and with some brownish hyphal incrustations in the inner zones. Hairs of two types, superficial and rooting, ornamented with warts and spines. Superficial hairs light brown, regularly septate, with blunt tips. Rooting hairs dark brown to black, densely ornamented with long and acutely pointed warts. Interascal tissue of paraphyses much branched and hyaline below, anastomosing along their length, becoming brown apically and roughened to granular, longer than the asci, the apical part densely branched, mid brown and verrucose. Setae present in the hymenium, long, dark brown and exceed the level of the hymenium by 500 µm or more; they are unbranched and pointed at the tip. Asci to 300 x 15 µm, cylindrical, 4- or 8-spored, slightly constricted below the tip, the operculum terminal, bifurcate or lobed at the base, the base often rounded. Ascospores 15-17 x 8-10 µm, ellipsoidal, biguttulate with 6–8 nuclei, hyaline, smooth with a cyanophilic covering layer, sometimes with rounded hyaline apiculate appendages.
