General DescriptionAscomata. Not known in axenic culture. In the type specimen, in linear groups, erumpent through the constricting linear host tissues; ellipsoid, 400-500 × 150 μm in surface view, with a short, obtuse, papillate beak; dark, thin-walled at maturity. Asci. Subcylindrical, straight or somewhat curved or musiform, 105-125 × 13-16 μm, usually 8-spored, ± 300 per ascoma. Ascospores. Sharply fusoid when young, sometimes sigmoid, becoming short-clavate, slightly flattened on one side, at first 3-transeptate (4-segmented) when longitudinal septa are formed, then 5-transeptate and remaining so in practically all cases; forming a single longitudinal septum through each of the 2 original central segments and rarely but definitely a second one longitudinally through either the upper central segment or the lower one (not seen in both concurrently); sometimes (uncommonly) forming a single vertical or oblique septum in the distal quarter of the mature ascospore; at full development, yellow-brown becoming gold-brown, with darker walls and septa (initial median septum often appearing weak and almost colourless), 19-22 × 7-8 μm, definitely constricted at median and slightly so at two other early transepta, subclavate, ellipsoid, often almost rhomboid in face view, very slightly inequilateral in side view.
