Stroma when present is merely found around the necks which sometimes coalesce together. The wall of the venter in surface view appears as a textura epidermoidea, individual cell 10-16 μm in diam. Peridium of venter 16-25 μm, composed externally of 2-3-layers of brown, oblong to polygonal, thick-walled cells, internally of 1-2-layers of hyaline, compressed, thin-walled cells; peridium of the neck is composed of brown, parallelly elongated cells, forming fringes at the apex. Asci 29-38 × 5-7.5 μm, oblong, sessile, unitunicate, 8-spored, with an inconspicuous apical ring, detaching from the hymenium early and floating freely within the centrum of ascoma. Paraphyses absent. Ascospores 8-11 × 2.5-3 μm, overlapping biseriate in ascus, straight to slightly curved, hyaline, 1-septate near the lower end, apiosporus, with a mucilaginous appendage at both ends, each up to 5 μm long and visible when ascospores are mounted in water. |
