Ascocarp Morphology. Ascocarp subglobose or globose, orifice or cavity absent, (0.3-)0.5-1.5-2.5(-4) cm in diameter, yellow or ochre or brown or red, smooth, peridium glabrous (smooth or minutely pruinose), color of spore-bearing tissue grey or yellow or brown (yellowish-brown), veins large and rare. Peridium (293-)383-536-689(-851) micron, outermost layers (53-)54-87-120(-133) micron, hyaline (pale yellowish) or yellow-brown (pale yellowish), anatomical structure pseudoparenchimatic with roundish cells or plectenchymatic, cell tangential dimension (5-)11-16-21(-30) micron, cell radial dimension (3-)4-9-14(-26) micron, innermost layers (319-)322-480-638(-784) micron, color hyaline, anatomical structure plectenchymatic, cell tangential dimension (3-)4-10-16(-26) micron, cell radial dimension 3-5-7(-10) micron, external cystidia absent. Sterile veins plectenchimatic.
Asci ans spores Morphology. Asci globose, major axis (58-)63-74-85(-98) micron, minor axis (37-)45-54-63(-72) micron, number of spores per ascus 1-3(-4), irregularly clustered.
