Subicula dark brown to black, effuse, thinly velutinous or tufted on leaves, twigs, or bark, occasionally occurring alone but usually closely associated with other sooty moulds. Mycelium composed of pale brown to brown, more or less cylindrical, finely roughened hyphae that are 4-5.6 µm wide with cells 16-35 µm long. Repent hyphae may be closely appressed to the surface of leaves or may form a dense irregular weft and may overgrow other sooty moulds. Conidiophores are macronematous, thinly scattered to crowded, and usually arise as upright branches of repent hyphae. They are composed of a straight main stalk up to 330 µm long, dark brown to black and 10.5-12.5 µm wide below, tapering to 7.2-8.1 µm wide toward the dark brown distal end, rough-walled below or throughout their length, thick-walled, septate with cells 21-30 µm long below and distally successively shorter to 7-9 µm long. The basal cell or one of the cells just above the base may be swollen up to 17 µm wide: basal cells bear 3 to 7 rooting hyphae. The main stalk of conidiophores terminates in a single mostly monoblastic conidiogenous cell: similar cells arise laterally on a few of the upper cells of the main stalk and these are single or paired, and sessile or on one- to several-celled stalks up to 90(- 140) µm long. Lateral branches may duplicate the pattern of the main stalk and bear one or more short lateral branches bearing conidiogenous cells. The latter are 10.8-18 µm long and 6.8-9 µm wide, ovoid to obpyriform to ampulliform to subconical, and terminate in a flattened scar 3-3.5 µm wide.
Following schizolytic release of the solitary conidium the conidiogenous cell usually proliferates and splits both the scar and the periclinal wall of the cell longitudinally so that the conidium scar appears as a crescent partially encircling the new conidiogenous proliferation. A series of up to 3 such scars can be formed in this way. Sometimes the conidiogenous cell may proliferate below the scar, with no rupture of the scar, to produce another lateral conidium on a short conico-truncate denticle.
Conidia are narrowly obclavate to ellipsoidal to subcylindrical, scarcely or slightly constricted at the septa, flattened to slightly raised at the basal scar, brown to dark brown, thin-walled, smooth, (1-)2- 5(-12)-septate and mostly (12.5-)14.5-48.5(-85) x 5-9(-9.7) µm. The ranges in length of seceded conidia are as follows: (1-septate) 12.5-16.2 x 5- 5.9 µm; (2-septate) 14.5-27 x 5-8.6 µm; (3-septate) 17-36 x 5.5-9 µm; (4-septate) 25-45 x 6.3-9 µm; (5-septate) 30-48.5 x 7.2-9 µm. Conidia with 6 septa (45-54 x 9 µm); 8 septa (59 x 9.3 µm), 10 septa (79 x 9.2 µm), and 12 septa (85 x 9.7 µm) are rare. Conidia can anastomose with other conidia, with hyphae, and with cells of conidiophores.
Capnofrasera dendryphioides is predominantly associated with other sooty moulds, on living leaves and on twigs and bark.
