Marginal zone stromatic, 70-120 μm thick, pseudoparenchymatous, delimiting ascomata within host tissue, visible as blackened lines on host surface. Neck 140-190 μm high, central, oblique as protruding from venter, then turning upright and broader near the host surface, clypeus around the lower half of the neck, up to 60 μm thick. Ostiolar canal 60-80 μm wide, filled with septate, hyaline periphyses pointeted upwards ostiole. Peridium up to 10 μm thick, composed of hyaline, strongly compressed cells. Asci 45-55 × 6-10 μm, ellipsoid, unitunicate, 8-spored, freely loosening in centrum, with a nonamyloid apical ring, aparaphysate. Ascospores 10-14 × 3-5 μm, ellipsoid to broadly clavate, hyaline, 1-septate near the lower end, the larger cell two and a half to three times the length of the smaller cell, straight to slightly curved. |
