Remarks (internal):Cladosporium paracladosporioides is morphologically similar to C. cladosporioides and the newly introduced C. iranicum, but the latter species differs in having narrower terminal and intercalary conidia that are often subrostrate or rostrate and narrower, 0-1(-2)-septate secondary ramoconidia with conidial chains being much longer forming up to 10 conidia in the terminal unbranched part of the chain. Cladosporium cladosporioides is distinct in that the conidia are usually aseptate, smooth and somewhat narrower. Phylogenetically the new species is closely allied to C. varians (see Fig. 1, part a; distance analyses in TreeBASE) but deviates in having longer and wider conidiophores, wider conidiogenous loci and hila and longer intercalary conidia and secondary ramoconidia (Braun et al. 2008b).

MycoBank MB517084. Figs. 52-53
Mycelium immersed and abundantly superficial; hyphae sparingly branched, 1.5-5 µm wide, septate, not constricted at septa, pale brown to medium brown or olivaceous-brown, septa mostly quite regular, sometimes 2-3 in short succession, smooth to asperulate or irregularly rough-walled, somewhat dimorphic, many hyphae look like macronematous conidiophores but are not yet sporulating, medium brown and smooth. Conidiophores macro- and micronematous, arising terminally and laterally from ascending or plagiotropous hyphae, erect, straight to mostly flexuous, sometimes hardly distinguishable from hyphae. Macronematous conidiophores cylindrical-oblong, non-nodulose, sometimes distinctly geniculate-sinuous due to sympodial proliferation, once or several times, unbranched or once branched, (17-)50-180(-300) x (2-)3-4 µm, pluriseptate, sometimes slightly constricted at septa, pale to medium brown or olivaceous-brown, smooth to irregularly asperulate or loosely delicately verruculose, walls thickened. Conidiogenous cells integrated, terminal, cylindrical-oblong, sometimes intercalary, occasionally geniculate-sinuous, 8-40 µm long, with 2-4 apical loci or up to five loci per cell, sometimes situated on lateral shoulders or on short lateral prolongations at the apex, protuberant, denticle-like, 1.5-2 µm diam, thickened and darkened-refractive. Micronematous conidiophores narrower and paler, filiform, unbranched, up to 165 µm long or even longer, 2-2.5(-3) µm wide, subhyaline to pale brown. Conidiogenous cells integrated, terminal, narrowly cylindrical-oblong, usually with a single apical locus, sometimes with few loci. Ramoconidia occasionally formed, hardly distinguishable from secondary ramoconidia. Conidia catenate, in branched chains, up to four conidia in the unbranched terminal part of the chain, straight, small terminal conidia obovoid, subglobose, sometimes obpyriform, 4-7(-14) x 3-3.5 µm (av. ± SD: 5.3 ± 1.1 x 3.1 ± 0.2), aseptate, intercalary conidia limoniform, fusiform to ovoid, 6-9(-11) x 3-3.5(-4) µm (av. ± SD: 7.7 ± 1.5 x 3.4 ± 0.3), 0(-1)-septate, with 1-2(-3) distal hila, secondary ramoconidia ellipsoid, fusiform to subcylindrical, with up to four distal hila, 7-26(-30) x (3-)3.5-5 µm (av. ± SD: 16.2 ± 6.2 x 4.0 ± 0.4), sometimes obclavate, up to 36 µm long, 0-3-septate, sometimes slightly constricted at septa, first septum median or often slightly to distinctly in the upper half, sometimes in the lower, with 2-3 septa sometimes irregular, cells of different size, septa darkened, pale brown, smooth or almost so to very finely asperulate, walls somewhat thickened, attenuated towards apex and base, hila protuberant, denticulate, broadly truncate, 0.8-2(-2.5) µm diam, thickened and darkened-refractive; microcyclic conidiogenesis occurring, forming secondary conidiophores.
Culture characteristics: Colonies on PDA olivaceous-grey to iron-grey and olivaceous-black, reverse greenish grey to olivaceous-black, woolly-fluffy, margin colourless to white, glabrous to feathery, very
narrow, aerial mycelium fluffy, loose, high, colonies somewhat shiny, without prominent exudates, sporulation profuse. Colonies on MEA olivaceous-grey to greenish olivaceous due to profuse sporulation, pale olivaceous-grey towards margins, somewhat zonate, reverse olivaceous-grey, velvety to felty, margin narrow, colourless to white, radially furrowed, colonies folded and wrinkled, aerial mycelium abundant, loose to dense, without conspicuous exudates, sporulating. Colonies on OA olivaceous-grey to iron-grey, smoke-grey due to mycelium and sporulation, reverse greenish black to leaden-grey, powdery to felty, margin colourless to white, narrow, glabrous, aerial mycelium loose, diffuse to dense, felty-fluffy, without exudates, sporulating.
