Sordariomycetes, Subclass Xylariomycetidae
Sexual morph: Stromata 0.5-0.6 mm diam., scattered, subglobose to globose, enclosing one to several perithecia, erumpent, with lower to middle part embedded in the substrate, surface dark-brown, smooth, carbonaceous immediately beneath the surface and between the perithecia, tissue beneath the perithecial layer inconspicuous. Ostioles obtusely conical, black. Peridium one-layered, composed of cells of textura angularis with large lumina, merging with the wood. Asci 80-100 μm × 6-9 μm, short-stipitate, with apical ring blueing in Melzer’s iodine reagent, cuneate, 1.5 μm high, 3 μm diam. Ascospores 9-12 × 5-6(-6.5) μm, light brown to brown, unicellular, ellipsoidal, with broadly rounded ends, with straight germ slit much less than spore-length. Asexual morph: undetermined.
