Dingleya verrucosa Trappe 1979
Sporocarps up to 3-5 cm in diam. when dried, subglobose to lobed, dark brown, surface verrucose with subangular warts 0.2-0.4 x 0.2-1.0 mm, small pubescent patches scattered among warts. Gleba dark brown with yellowish white trama and labyrinthine chambers 0.2-1.0 mm wide, lined and filled with a hymenium of paraphyses, asci and spores.
Peridium two-layered; epicutis 50-150 µm thick, of elongate to ± isodiametric cells 8-25 (-30) µm in diam., with yellowish brown walls 2-3 µm thick, grading into the subcutis of interwoven, hyaline hyphae 4-6 µm in diam. Asci 230-280 x 25-30 µm, cylindrical, hyaline, 8-spored, thin-walled, nonamyloid. Paraphyses ± 2 µm in diam., hyaline, thin-walled, elongate with rounded apex, equal to or shorter in length than the asci.
Spores (Fig. 4) ellipsoid, 19-28 x 15-18 µm excluding the cyanophilic ornamentation of vinaceous brown, rounded knobs and ridges 4-12 x 2-5 µm, walls up to 3 µm thick, smooth and hyaline in youth.
Etymology: Latin verrucosa (warty), in reference to the peridial surface.
