Glonium graphicum  

Anamorph: unknown.
Teleomorph: ascostromata to 1.5 x 0.25 mm, superficial, formed on an effuse subiculum composed of thick-walled dark brown rarely branched hyphae. Peridium with side walls composed of very dark, thick-walled brown-black cells, basal region similar, with a layer of yellow-brown thin-walled angular cells forming the cavity floor. Interascal tissue of branched and anastomosed pseudoparaphyses 1.5-2 µm diam, apically encrusted with minute yellow-brown particles, tending to degenerate at maturity. Asci 95-125 x 9-11 µm, cylindrical, short-stalked, the apex rounded, thick-walled and fissitunicate, not staining in iodine, 8-spored. Ascospores (16-) 18-21 x 5.5-6.5 µm, fusiform-ellipsoidal, the ends acute to obtuse, constricted at the single median to slightly supramedian septum, fairly thin-walled, hyaline, smooth, without a distinct epispore, gelatinous sheath or appendages.
