Remarks (public):The examination of type material of Acrosporella sarmentorum showed that this species has to be assigned to Cladosporium. The conidiogenous loci and conidial hila are coronate and the amero- to phragmosporous conidia are formed in branched acropetal chains. Since A. sarmentorum is the type species of Acrosporella Riedl & Ershad, the latter genus becomes a facultative synonym of Cladosporium. This species is a saprobic hyphomycete. The colonies, conidiophores and conidia resemble those of Cladosporium delicatulum Cooke, but the conidiophores are frequently branched. C. sarmentorum differs from most other Cladosporium species in having barely geniculate conidiogenous cells with less conspicuous, barely protuberant, barely or only slightly darkened-refractive conidiogenous loci. The loci are cladosporioid, but the central dome is not very conspicuous and the surrounding rim is rather low.

Description:Colonies on dead stems, wood and tendrils, punctiform, scattered to aggregated, or forming dense villose black patches or layer. Mycelium internal, sometimes also external; hyphae pale olivaceous to medium brown or olivaceous-brown, 2–7 µm diam., septate, smooth. Stromata lacking to well-developed, immersed to erumpent, 20–120 µm diam., dark brown, composed of swollen hyphal cells, 3–15 µm diam., brown, wall up to 1.5 µm thick, often with diffuse aggregations and layers of stromatic hyphal cells, often forming superficial strands of swollen cells, up to 10 µm diam., with constrictions at the septa, monilioid. Conidiophores solitary, caespitose, in small to large, loose to moderately dense fascicles, arising from swollen hyphal cells or stromata, erect to decumbent, 20–250 — 3–9 µm, simple to frequently branched in the upper portion, with short lateral branchlets or long branches, up to 90 µm in length, subcylindrical to sinuous, slightly geniculate, rarely subnodulose, pluriseptate throughout, often densely septate and constricted at the septa, pale to dark brown or olivaceous-brown, tips usually paler, subhyaline to olivaceous, wall 0.5–1(–2) µm thick, smooth to somewhat rough-walled or rugose, cells sometimes with distinct lumina, provoking the impression that the walls are very thick, occasionally guttulate, rarely with monopodial rejuvenation. Conidiogenous cells integrated, terminal and intercalary, 5–25 µm long, at first often monoblastic, later polyblastic, sympodial, but conidiogenous cells not or only slightly geniculate, conidiogenous loci (1–)1.5–2(–2.5) µm diam., less conspicuous than in most other species of the genus, barely or only slightly protuberant, slightly darkened-refractive, central dome not very conspicuous. Conidia solitary and catenate, in short simple to branched chains, subglobose, broadly ellipsoid-ovoid, fusiform, subcylindrical, limoniform, (3–)5–24(–30) — (2–)4–7(–8) µm, 0–3(–5)-septate, often slightly constricted at the septa, small, young conidia subhyaline, later olivaceous, olivaceous-brown to medium brown, wall up to 1 µm wide, smooth, rarely faintly rough-walled, ends rounded to somewhat attenuated, hila not or somewhat protuberant, 0.75–2 µm diam., slightly darkened-refractive; occasionally with microcyclic conidiogenesis.
