Remarks (internal):Cladosporium melospermae, occurring on living leaves and inflorescences of the endemic host species Melosperma andicola, is morphologically close to C. variabile (Cooke) G.A. de Vries but the later species, which causes distinct leaf spots on spinach, is easily distinguishable by having longer, (6.5-)10-45(-55) µm, 0-4(-5)-septate conidia. Cladosporium mimulicola U. Braun known from North America on Mimulus sp., is quite distinct by having shorter and narrower conidiophores arising from superficial hyphae, smooth and narrower conidia, (2.5-)3-5(-6.5) µm, and narrower conidiogenous loci and hila (SCHUBERT 2005b). Type material of C. digitalicola Z.Y. Zhang, T. Zhang & W.Q. Pu, a species also recorded from a member of the Scrophulariaceae, could not be traced. Therefore its status remains still uncertain but conidia are described to be shorter, 0-4-septate and conidiophores longer and narrower, 45-502 — 4.0-7.9 µm (ZHANG, WEI & ZHANG 1998).

Description:On leaves and inflorescences (sepals), without conspicuous leaf spots, but sometimes with pale brownish discolorations, somewhat faded. Colonies amphigenous, punctiform, scattered to effuse, brownish, sometimes velvety. Mycelium internal, subcuticular to intraepidermal; hyphae branched, (3–)5–10 µm wide, septate, not constricted at the septa, pale brown to pale medium brown or somewhat olivaceous-brown, sometimes subhyaline, smooth or almost so, walls more or less thickened, forming aggregations. Stromata small, substomatal to intraepidermal, 15–60 µm diam., few layers deep, composed of swollen hyphal cells or hyphal aggregations, cells 8–15 µm diam., medium brown, smooth, thick-walled. Conidiophores solitary or usually in small loose fascicles, arising from hyphae aggregations or stromata, emerging through stomata or erumpent through the cuticle, erect, straight to flexuous, cylindrical, geniculate-sinuous towards the apex and often coralloid at the apex, non-nodulose, unbranched, occasionally branched, 20–145 — 4.5–8 µm, 0–5-septate, not constricted at the septa, medium brown, somewhat paler towards the apex, smooth to verruculose, walls thickened, up to 1(–1.5) µm thick, often distinctly two-layered, base often somewhat swollen. Conidiogenous cells integrated, terminal or intercalary, cylindrical, often geniculate-sinuous, coralloid, proliferation distinctly sympodial, with a single or few conidiogenous loci situated on small shoulders or small lateral projections, protuberant, coronate but dome and rim often flat and not distinctly differentiated, 2–3 µm wide, thickened and somewhat darkened-refractive. Conidia solitary or in short unbranched, rarely branched chains, straight, obovoid, broadly ellipsoid to subcylindrical or somewhat irregular, 9–35 — (8.5–)10–15 µm, 0–1(–2)-septate, septum somewhat in the upper or lower half, sometimes slightly constricted, medium brown, coarsely verrucose, ornamentation up to 1 µm high, thick-walled, apiculate, base sometimes attenuated, stalk-like, cells sometimes with large oil drops, hila more or less protuberant, truncate, dome and rim flat, dome often not higher than the surrounding rim, 2–3 µm wide, thickened, somewhat darkened-refractive; microcyclic conidiogenesis occurring.
