Sporocarps 15-35 mm in diam., subglobose, sparingly to densely tomentose, brown with a reticulum of pale brownish yellow to yellowish brown, low meandering ridges, between the ridges even to verrucose with irregular, rounded warts. Gleba white in youth, in age the trama becoming light brown, with labyrinthine, often branching, mostly empty chambers 2-10 x 0.5-2.0 mm, lined with a hymenium of asci and paraphyses that is pale brown in youth, becoming brown to dark brown at maturity. Odour faintly sweet. Peridium two-layered; epicutis 100-250 µm thick, of interwoven hyphae 4-7 µm in diam. with brown walls 0.5-1.5 µm thick and scattered angular to inflated cells up to 15 µm in diam., with a turf of emergent, round-tipped, pale brown, straight to sinuous, smooth or occasionally granulated hyphal tips 10-75 x 3-4 µm, walls 0.5-1.0 µm thick; subcutis of hyaline, interwoven, thin-walled hyphae 3-5 (-8) µm in diam. Trama tissue similar to that of subcutis. Asci 300-345 x 22-28 µm, (2-) 8 spored, long tapered to an obscurely forked base, the lateral walls 1-2 fim thick, the tip wall ± 1 µm thick. Paraphyses 5-7 µm in diam., septate, thin-walled, less than half as long as the asci. Spores (Fig. 3) globose, 18-25 µm in diam., excluding the cynanophilic ornamentation of crowded, rounded warts 1-4 x 1-5 (-7) µm, smooth, hyaline in youth, light brown at maturity, walls 1.5-2 µm thick.

Etymology; Latin varius (various) in reference to the considerable variability in size and proportionate development of chambers and trama.
