<strong>Cladosporium</strong> herbarum species complex<br />
Fig. 37. <strong>Cladosporium</strong> subinflatum (CPC 12041). Macro- <strong>and</strong> micronematous conidiophores <strong>and</strong> conidia. Scale bar = 10 µm. K. Schubert del.<br />
<strong>Cladosporium</strong> subinflatum K. Schub., Zalar, Crous & U. Braun,<br />
sp. nov. MycoBank MB504579. Figs 37–39.<br />
Etymology: Refers to its nodulose conidiophores.<br />
Differt a Cladosporio bruhnei conidiophoris cum nodulis angustioribus, 3–6.5 µm<br />
latis, conidiis brevioribus, 4–17(–22) µm longis, spinulosis, cum spinulis ad 0.8 µm<br />
longis; et a Cladosporio spinuloso conidiophoris nodulosis, conidiis spinulosis, cum<br />
spinulis brevioribus, ad 0.8 longis, locis conidiogenis et hilis latioribus, (0.5–)1–2<br />
µm latis.<br />
Mycelium unbranched or occasionally branched, 1.5–3 µm wide,<br />
later more frequently branched <strong>and</strong> wider, up to 7 µm wide,<br />
septate, not constricted at the septa, hyaline or subhyaline, almost<br />
smooth to somewhat verruculose or irregularly rough-walled, walls<br />
unthickened. Conidiophores mainly macronematous, sometimes<br />
also micronematous, arising terminally from ascending hyphae<br />
or laterally from plagiotropous hyphae, erect or subdecumbent,<br />
straight or flexuous, sometimes bent, cylindrical, nodulose, usually<br />
with small head-like swellings, sometimes swellings also on a<br />
lower level or intercalary, occasionally geniculate, unbranched,<br />
occasionally branched, (5–)10–270 × (1.5–)2.5–4.5(–5.5) µm,<br />
www.studiesinmycology.org<br />
swellings 3–6.5 µm wide, aseptate or with few septa, not constricted<br />
at the septa, pale brown, pale olivaceous-brown or somewhat<br />
reddish brown, smooth, usually verruculose or irregularly roughwalled<br />
<strong>and</strong> paler, subhyaline towards the base, walls thickened,<br />
sometimes appearing even two-layered, up to 1 µm thick.<br />
Conidiogenous cells integrated, usually terminal or conidiophores<br />
reduced to conidiogenous cells, cylindrical, nodulose, usually with<br />
small head-like swellings with loci confined to swellings, sometimes<br />
geniculate, 5–42 µm long, proliferation sympodial, with several loci,<br />
up to four situated at nodules or on lateral swellings, protuberant,<br />
conspicuous, denticulate, (0.8–)1–2 µm diam, thickened <strong>and</strong><br />
darkened-refractive. Conidia catenate, in branched chains, more<br />
or less straight, numerous globose <strong>and</strong> subglobose conidia, ovoid,<br />
obovoid, broadly ellipsoid to cylindrical, 4–17(–22) × (2.5–)3.5–<br />
5.5(–7) µm [av. ± SD, 11.7 (± 4.6) × 4.5 (± 0.8) µm], 0–1(–2)-<br />
septate, not constricted at septa, pale brown or pale olivaceousbrown,<br />
ornamentation variable, mainly densely verruculose to<br />
echinulate (loosely muricate under SEM), spines up to 0.8 µm<br />
high, sometimes irregularly verrucose with few scattered tubercles<br />
