Family: MytilinidiaceaeGenus: Glyphium
Ascomata 0.75-1.5 mm high x 0.5-0.75 mm wide at the apex x 0.1-0.2 mm thick, hatchet-shaped, taller than broad, laterally flattened, widening from a narrow base to a convex apical ridge provided with a slit, black, transversely striate, erect, superficial, scattered to gregarious, in no particular alignment, formed on a subiculum of brown, smooth-walled, sparsely septate hyphae originating from each ascomatal base, 1-1.5 mm diam. Peridium composed of hyaline, thin-walled, elongate-compressed inner cells that merge into dark brown, thick-walled, rounded-prismatic outer cells. Interascal tissue of pseudoparaphyses, 0.5-1 µm diam, filiform, hyaline, smooth, septate, branched. Asci (250-)350-430 x 9-10 µm, elongate-cylindrical with a long tapering base, apex rounded and thick-walled, J-, with two observable layers, 8-spored, arising parallel to each other from the base of the ascoma. Ascospores ca 300-400 x 2-3 µm (length measured within the asci), filiform with rounded ends, yellow-brown, thin-walled, smooth, multi-septate, lying parallel or spiralled, remaining intact or fragmenting within the asci, septa 6-10 µm apart, remaining intact within the asci, fragments outside the asci of many sizes and regularly in excess of 100 µm in length.
