Basionym Thecotheus platyapiculatus I. Kušan & Matočec, Sydowia, 67: 52 (2015).
Diagnosis Differs from the most similar species Thecotheus keithii (W. Phillips) Aas by consistently flat, plateshaped apiculi 0.2–0.7 μm high, (0.5)1.9–2.8 μm wide; in prevalence of slightly heteropolar and/or bilaterally symmetrical ascospores; markedly strangulate asci and turbinate apothecia with pinkish tinges when fresh. Paraphyses with inflated tips contain subhyaline vacuolar bodies lacking internal pigments and/or pigmented encrustations. Medullary excipulum comparatively thinner than in T. keithii, without globose to subglobose and much wider elongate cells, composed only of narrow hyphae up to 5 μm in diam.
