Daldinia sacchari Dargan & Thind, Kavaka 12: 114. 1984.

Stromata turbinate, sessile or with short, stout stipe, solitary, with inconspicuous to conspicuous perithecial mounds, 8-10 mm diam x 6-10 mm high; surface vinaceous buff (86) to grayish sepia (106); dull reddish brown granules immediately beneath surface, without apparent KOH-extractable pigments; the tissue between perithecia whitish, gray, or brown, pithy to woody; the tissue below the perithecial layer composed of alternating zones, the darker zones dark brown, pithy to woody, 0.2 mm thick, the lighter zones whitish, pithy to woody, persistent, 1-2 mm thick.

Perithecia obovoid, 0.3 mm diam x 0.8 mm high.

Ostioles at the same level as the stromatal surface.

Asci 135-175 mm total length x 9.5-11 mm broad, the spore-bearing part 90-110 mm long, the stipe 50-65 mm long, with apical ring bluing in Melzer's iodine reagent, discoid, 0.5 mm high x 3 mm broad.

Ascospores brown, unicellular, ellipsoid-inequilateral, with narrowly to, infrequently, broadly rounded ends, 15.5-18 x 6.5-7.5 mm, with straight germ slit spore-length or nearly so on convex side; perispore indehiscent in 10% KOH; epispore smooth.
