Mycelium on stems and leaves, amphigenous, effused or thin patches, subpersistent or evanescent, hyphae ca 4-9 µm wide, appressoria nipple-shaped or slightly lobed, sometimes hardly developed, conidiophores erect, foot-cells nearly cylindric, (30-)40-75(-80) x 10-13 µm, followed by 1-3 shorter cells, frequently constricted at the basal septum (ca 5-10 µm wide), basal septum sometimes somewhat away from the branching point of the mycelium, conidia in chains, ellipsoid-ovoid to doliform, ca 25-42 x 14-24 µm, germ tubes apically or subapically arising, moderately long, ending in an unlobed appressorium. Cleistothecia scattered to subgregarious, (70-)85-150 µm in diam, cells irregularly shaped, size variable, (5-)10-25(-35) µm diam, appendages numerous, mycelioid, in the lower half of the ascocarp, 0.5-2.5 times as long as the cleistothecial diam, rarely exceeding, smooth to verrucose, septate, thin-walled, ± brown when mature, simple, rarely irregularly branched, 4-9.5 µm wide, interwoven with each other and with the mycelium, often forming a dense felt around the ascocarps, ca 5-15 asci, rarely more, stalked, ca (45-)50-80(-95)x 25-45(-50) µm, 2-spored, rarely 3 or 4 spores, ellipsoid-ovoid, 20-25(-30) x 12-18.5 µm, the asci are usually filled with oil-drops, even when mature.
