Description: | Mycelium superficial, composed of dark brown, 7-12 μm wide hyphae, forming sparse mat with hyphae penetrating depply into underlying host tissue. Ascomata seated on mycelium mat, subglobose to turbinate, 420-545 μm wide, 390-510 μm high, becoming cupulate, densely gregarious, tuberculate, non-ostiolate, usually with a sterile base, up to 170 μm high. Quellkörper well-developed, composed of mucilaginous, hyaline, thick-walled cells with lumen, elongating from the top toward the base, finally touching the basal placenta-like pedestal which bears the radially arranged asci around this tissue. Peridium laterally 45-60 μm wide, composed of 5-7-layered of dark brown, thick-walled cells, the base of ascoma usually enlarges to form a sterile base, peridium at the apex usually narrower than the lateral peridium and, composed of compressed cells; the outer-most 1-2 layers of dark and opaque cells. Munk pores present in peridial cell walls. Asci clavate, with a slender, easily broken stalk, 17-23 × 9-12 μm in the ascospores 8-10 × 3-4.5 μm, oblong, straight to slightly curved, yellowish to pale brown, 1-celled, usually with two large lumen-like guttules, overlapping biseriate to fasciculate in ascus. | |||
