Cladosporium herbarum species complex Fig. 30. Cladosporium pseudiridis (CBS 116463). A–C. Conidiophores and conidia. D. Part of a conidiogenous cell showing a protuberant cladosporioid conidiogenous locus. E–F. Conidia. Scale bars = 10 µm. convex to raised, deep into the agar, with age few large prominent exudates formed, sparingly sporulating. Colonies on MEA attaining 7 mm diam after 14 d at 25 ºC, olivaceous-grey, pale olivaceousgrey to pale rosy-buff due to abundant aerial mycelium covering almost the whole colony, iron-grey reverse, margin colourless or white, broad, regular, more or less glabrous, aerial mycelium fluffy, dense, high, growth convex to umbonate, sometimes with elevated colony centre, prominent exudates lacking, sporulation sparse. Colonies on OA attaining 8 mm diam after 14 d at 25 ºC, white, pale buff to pale olivaceous-grey in the centre, margin grey-olivaceous, olivaceous- to iron-grey reverse, margin entire edge or somewhat undulate, somewhat feathery, growth raised with a somewhat depressed centre forming an elevated outer rim, without prominent exudates, sporulation more abundant. Specimen examined: New Zealand, Auckland, Mt. Albert, Carrington Road, Unitec Campus, isolated from large leaf lesions on Iris sp. (Iridaceae), 15 Aug. 2004, C.F. Hill, CBS-H 19861, holotype, culture ex-type CBS 116463 = LYN 1065 = ICMP 15579. Substrate and distribution: On living leaves of Iris sp.; New Zealand. Notes: Cladosporium pseudiridis closely resembles C. iridis, a common and widespread species causing leaf spots on numerous Iris spp. and a few additional hosts of the host family Iridaceae, but the latter species is easily distinguishable by having longer and narrower, more frequently septate conidia, (18–)30–75(–87) × (7–)10–16(–18) µm, (0–)2–6(–7)-septate. www.studiesinmycology.org It is unlikely that C. pseudiridis is of New Zealand origin since the genus Iris is not indigenous to New Zealand. All Iris species that are found in this country have been introduced, mainly for horticultural purposes. The species is, therefore, probably more common than indicated above. However, within the course of the recent monographic studies in the genus Cladosporium numerous herbarium specimens, mainly of European origin, have been examined and proved to be correctly identified agreeing with the species concept of C. iridis. Additional collections and cultures are necessary to determine its distribution. Cladosporium ramotenellum K. Schub., Zalar, Crous & U. Braun, sp. nov. MycoBank MB504577. Figs 31–33. Etymology: Refers to the morphological similarity with Cladosporium tenellum. Differt a Cladosporio cladosporioide conidiophoris et conidiis leniter angustioribus, 2–4(–5) µm latis, conidiis 0–2(–3)-septatis, semper verruculosis; et a Cladosporio tenello locis conidiogenis non numerosis et non aggregatos ad apicem, conidiis longioribus et angustioribus, 2.5–35 × 2–4(–5) µm, 0–3-septatis. Mycelium unbranched or only sparingly branched, 1.5–4 µm wide, septate, without swellings and constrictions, hyaline or subhyaline, smooth, sometimes irregularly rough-walled, walls unthickened. Conidiophores solitary, macronematous and micronematous, arising as lateral branches of plagiotropous hyphae or terminally from ascending hyphae, erect, straight or slightly flexuous, cylindrical, neither geniculate nor nodulose, without head-like swollen apices or intercalary swellings, unbranched, sometimes 137
Schubert et al. Fig. 31. Cladosporium ramotenellum (CPC 12043). Conidiophores and conidia. Scale bar = 10 µm. K. Schubert del. branched, branches often only as short lateral prolongations, mainly formed below a septum, 14–110 × 2–4 µm, septate, not constricted at the septa, subhyaline to pale olivaceous or brown, smooth to minutely verruculose, walls unthickened, sometimes guttulate. Conidiogenous cells integrated, terminal, sometimes also intercalary, cylindrical, not geniculate, non-nodulose, 10–28(–50) µm long, proliferation sympodial, with few conidiogenous loci, mostly 1–3, loci sometimes situated on small lateral prolongations, protuberant, 0.5–1.5(–2) µm diam, thickened and somewhat darkened-refractive. Ramoconidia formed, cylindrical-oblong, up to 47 µm long, 2–4 µm wide, 0–1-septate, rarely up to 4-septate, subhyaline to very pale olivaceous, smooth or almost so, with a broadly truncate base, without any dome and raised rim, 2–3 µm wide, not thickened but somewhat refractive. Conidia numerous, polymorphous, catenate, in branched chains, straight, sometimes slightly curved, small terminal conidia numerous, globose, subglobose or ovoid, obovoid or limoniform, 2.5–7 × 2–4(–4.5) µm [av. ± SD, 5.1 (± 1.3) × 3.1 (± 0.6) µm], aseptate, without distal hilum or with a single apical scar, intercalary conidia ellipsoid to subcylindrical, 8–15 × 3–4(–4.5) µm [av. ± SD, 11.5 (± 2.4) × 3.6 (± 0.5) µm], 0–1-septate; secondary ramoconidia subcylindrical to cylindrical-oblong, 17–35 × 3–4(–5) µm [av. ± SD, 22.5 (± 5.6) × 3.7 (± 0.5) µm], 0–3-septate, not constricted at the septa, subhyaline to very pale olivaceous, minutely verruculose (granulate under SEM), walls unthickened or almost so, apex broadly rounded or slightly attenuated towards apex and base, sometimes guttulate, hila protuberant, conspicuous, 0.8–1.5(–2) µm diam, somewhat thickened and darkened-refractive; microcyclic conidiogenesis occurring. Cultural characteristics: Colonies on PDA reaching 46–49 mm diam after 14 d at 25 ºC, olivaceous to grey-olivaceous due to abundant sporulation, appearing zonate in forming concentric zones, margin entire edge to slightly undulate, white, glabrous, aerial mycelium absent or sparse, growth flat with a somewhat folded and wrinkled colony centre, without prominent exudates, sporulation profuse. Colonies on MEA reaching 48–49 mm diam after 14 d at 25 ºC, grey-olivaceous to olivaceous-grey, velvety, olivaceous-grey to 138
