Original description Foliicolous, epiphyllous, conidiomata sporodochial, scattered, on necrotic spots caused by the rust fungus Melampsoridium alni, erumpent, pulvinate, dark brown to blackish, usually 40-100 µm diam., pulverulent. Conidiophores and conidiogenous cells arising from a stromatic hyphal cushion-like base, composed of swollen, sometimes even subglobose, to filiform elements, simple or branched, often constricted at septa, subhyaline to pale olivaceous or very pale olivaceous-brown, thin-walled, smooth; conidiogenous cells integrated in simple or branched conidiophores, terminal, or single conidiogenous cells directly arising from swollen stromatic cells, usually 8-15 × 3-7 µm, subcylindrical-conical to ampulliform, pale greenish, olivaceous or very pale olivaceous-brown, thin-walled, smooth, unilocal, monoblastic, determinate, conidiogenous loci truncate, flat, 2.5-5 µm wide, unchanged (neither thickened nor darkened). Conidia formed singly, some conidia phragmosporous to dictyosporous, broadly ellipsoid to oblong obovoid, usually with 2-5 transverse and occasionally (= 1%) 1(-2) oblique to longitudinal eusepta, about 20-35 × 6-12 µm, but most conidia cheiroid, composed of a subglobose, obovoid to rhomboid, 1-2-celled base, 10-15 × 6-12 µm, and two arms, composed of (1-)2-5 cells, 15-35 × 7-12(-14) µm, arms subequal in length to distinctly unequal, divergent or non-divergent, dense, total length of cheiroid conidia 25-45 µm, usually 4-6-euseptate, usually distinctly constricted at the septa, conidia very pale to medium olivaceous or olivaceous-brown, thin-walled (up to about 0.5 µm), smooth, apices rounded, base (hilum) rounded to truncate, 2.5-5 µm wide.
