Crous et al. Fusicladium rhodense Crous & M.J. Wingf., sp. nov. MycoBank MB504542. Fig. 27. Etymology: Named after the Greek Island, Rhodos, where it was collected. Fusicladio africano similis, sed locis conidiogenis angustioribus, 1.5–2 µm latis, et differt a F. pini ramoconidiis formantibus. Mycelium consisting of smooth to finely roughened, medium brown, branched, septate, 1.5–3 µm wide hyphae, frequently forming hyphal coils, giving rise to solitary, micronematous conidiophores. Conidiophores reduced to conidiogenous cells that are terminal or lateral on hyphae, medium brown, smooth, subcylindrical, subdenticulate, erect, or more distinct, up to 15 µm tall, 1.5–2 µm wide, mono- to polyblastic; scars flat-tipped, somewhat darkened and thickened, but not refractive. Conidia in branched or unbranched chains of up to 15, pale brown in younger conidia, becoming medium brown, smooth, subcylindrical, 0–3-septate, tapering slightly towards the subtruncate ends, straight, but at times slightly curved, (8–)12–16(–20) × (2–)2.5–3(–4) µm; ramoconidia (0–)1(–3)-septate, 12–20 × 3–4 µm; conidia (0–)1-septate, 8–17 × 2–3 µm; hila somewhat darkened and thickened, not refractive, 1–1.5 µm wide. Fig. 26. Fusicladium ramoconidii (CBS 462.82). Conidiogenous cells with ramoconidia and conidia. Scale bar = 10 µm. brown on mononematous conidiophores, smooth, 3–15 × 2–3(–4) µm; proliferating sympodially, loci slightly thickened, darkened and refractive, 0.5–1 µm wide. Conidia occurring in branched chains, narrowly ellipsoid to subcylindrical, pale olivaceous, guttulate; ramoconidia (0–)1(–3)-septate, (12–)15–17(–20) × 2(–3) µm; conidia occurring in short chains (–15), 0–1-septate, (8–)10–12(– 16) × 2(–3) µm; hila slightly thickened and darkened, not refractive, 0.5–1 µm wide. Cultural characteristics: Colonies erumpent, with sparse aerial mycelium and smooth margins on PDA, hazel to fawn (surface), with a thin, submerged margin; reverse brown-vinaceous; on OA hazel to fawn (surface) with a wide, fawn, submerged margin. Colonies reaching 25 mm diam on PDA after 1 mo at 25 °C in the dark; colonies fertile. Specimen examined: Netherlands, Baarn, De Vuursche, needle of Pinus sp. (Pinaceae), 12 Apr. 1982, G.S. de Hoog, holotype CBS H-19908, culture ex-type CBS 462.82. Notes: This strain has been deposited in the CBS collection as Pseudocladosporium hachijoense (Matsush.) U. Braun. However, its ramoconidia and conidia are smaller than those cited by Matsushima (1975) (ramoconidia up to 30 µm long, conidia 10–21 × 2–4 µm). Although it clusters with F. pini in the LSU phylogeny, there are 13 bp differences in their ITS sequence data. Furthermore, F. ramoconidii has ramoconidia which are absent in F. pini, and has a faster growth rate, and hazel to fawn colonies, compared to the greyish sepia colonies of F. pini. The well-developed, septate conidiophores and ramoconidia are reminiscent of F. brevicatenatum, which differs, however, by its longer and wider ramoconidia, up to 30 × 6(–7) µm, as well as larger conidiogenous loci and conidial hila, 1.5–3 µm diam. Cultural characteristics: Colonies spreading, somewhat erumpent, with moderate aerial mycelium and crenate margins on PDA, uneven, greyish sepia (surface), margins fuscous-black; reverse fuscous-black; on OA smooth, spreading, with sparse aerial mycelium and even, regular margins, greyish sepia; on SNA spreading, smooth, even margins, sparse aerial mycelium, greyish sepia (surface). Colonies reaching 9 mm diam on PDA after 2 wk at 25 °C in the dark; colonies fertile. Specimen examined: Greece, Rhodos, on branches of Ceratonia siliqua (Fabaceae), 1 Jun. 2006, P.W. Crous & M.J. Wingfield, holotype CBS H-19910, culture ex-type CBS 121641 = CPC 13156. Note: Fusicladium rhodense has a typical pseudocladosporiumlike morphology in culture, with conidial scars that are somewhat darkened and thickened. Venturia hanliniana (U.
