 Description: Stroma immersed, cusion-like, up to 6 mm high, 8 mm wide, forming pustules on the bark, composed of hyaline to pale brown, densely interwoven hyphae, sometimes mixed with host tissue. Ascomata, separate, insert at different levels in stroma, globose, with a long neck, 468-746 μm in diam., not including the neck. Necks cylindrical up to 1040 μm long, 273 μm wide, with numerous periphses. Peridium 29-35 μm ,composed of 8-12 layers of pseudoparenchymatous cells, greyish brown, thin-walled, forming textura angularis epidermoidea. Asci cylindrical, unitunicate, periphyery, 8-spored, 142-170 × 15-20 μm, paraphysate, with apical ring, non-amyloid, uniseriate, broadly elliptical, 3-5 septate, slightly constricted at the septa, with 1-2 longitudinal septa in each cell, occasionally oblique.

 Note: This species is very variable according to the substrates it colonized (Barr, 1983). Conidiomata of Pleurocytospora vestita are also associated with upper part of stroma prior to formation of ascostroma or sometimes concurrently with ascostroma. No associated conidiomata is found in Taiwan materials.
