Schubert et al. Fig. 48. Cladosporium variabile (CPC 12753). A. Survey of hyphae that grow on the agar surface. Some of the fungal cells have a swollen appearance and could develop into a “foot cell” that gives rise to a conidiophore. B. A number of aerial hyphae obstruct the swollen, large structures on the agar surface, which give rise to conidiophores. Some of them appear ornamented. C. A series of conidia formed on a conidiophore (bottom of the micrograph). D. Detail of the ornamented conidia. The ornamentations are isolated and dispersed. Note also the ornamentation-free scar zone and the hilum of the left cell. E. Two conidia behind an aerial hypha. F. Two conidiophores forming secondary ramoconidia. Note the bulbous shape of the spore-forming apparatus. This micrograph is from an uncoated sample. Scale bars: A–C, F = 10 µm, D = 2 µm, E = 5 µm. Teleomorph: Davidiella variabile Crous, K. Schub. & U. Braun, sp. nov. MycoBank MB504583. Davidiellae tassianae similis, sed ascosporis maioribus, (22–)26–30(–35) × (7–)7.5– 8(–9) µm, et ascis latioribus, plus quam 18 µm. Ascomata pseudothecial, black, superficial, situated on a small stroma, globose, up to 250 µm diam, with 1–3 ostiolate necks; ostioles periphysate, with apical periphysoids present; wall consisting of 3–6 layers of dark brown textura angularis, textura epidermoidea in surface view. Asci fasciculate, bitunicate, subsessile, obovoid to broadly ellipsoid, straight to slightly curved, 8-spored, 70–95 × 18–28 µm; with pseudoparenchymatal cells of the hamathecium persistent. Ascospores tri- to multiseriate, overlapping, hyaline, with irregular lumina, thick-walled, straight to slightly curved, fusoid-ellipsoidal with obtuse ends, widest near the middle of the apical cell, medianly 1-septate, not to slightly constricted at the septum, at times developing a second septum in each cell, several ascospores with persistent, irregular mucoid sheath, (22–)26–30(–35) × (7–)7.5–8(–9) µm. Mycelium immersed and superficial, irregularly branched, aerial mycelium twisted and spirally coiled, 1–3 µm wide, septate, sometimes with swellings or small lateral outgrowths, hyaline to subhyaline, smooth, walls unthickened, hyphae which give rise to conidiophores somewhat wider, 3–4.5 µm, subhyaline to pale brown, almost smooth to minutely verruculose, sometimes enveloped by a polysaccharide-like cover. Conidiophores usually macronematous, but also micronematous, arising terminally from ascending hyphae or laterally from plagiotropous hyphae. Macronematous conidiophores erect, more or less straight to flexuous, often distinctly geniculate-sinuous forming lateral shoulders or unilateral swellings, sometimes zigzag-like or somewhat coralloid, nodulose, swellings at first terminal, then becoming lateral due to sympodial proliferation, often as distinct lateral shoulders, unbranched, sometimes once branched, 6– 180 × (2.5–)3–6 µm, swellings (3–)6–11 µm wide, septate, not constricted at the septa, pale to medium olivaceous-brown or brown, usually verruculose, walls somewhat thickened, about 1 µm thick, sometimes appearing to be two-layered. Conidiogenous cells integrated, terminal and intercalary, cylindrical, nodulose to nodose, 152
