nov. Fig. 5 Fig. 5 Scleroramularia abundans (CPC 18170). A. Colony on malt extract agar. B. Colony on synthetic nutrient-poor agar (note sclerotia). C–I. Chains of conidia (note hyphal bridge in H). Scale bars = 10 μm MycoBank MB517548. Etymology: Named after its abundant sclerotial production

in culture. Scleroramulariae asiminae morphologice valde similis, sed formatione abunda sclerotiorum et coloniis olivaceo-griseis in cultura distinguitur. On SNA. Mycelium creeping, superficial and submerged, https://www.selleckchem.com/ATM.html consisting of hyaline, smooth, branched, septate, 1–2 μm diam hyphae. Conidiophores mostly reduced to conidiogenous cells, or with one supporting cell. Conidiogenous cells solitary, erect, intercalary on hyphae, subcylindrical, straight, with 1–2 terminal loci, rarely with a lateral locus, 2–10 × 1.5–2.5 μm; scars thickened, darkened and somewhat refractive, 0.5–1 μm wide. Conidia in branched chains, hyaline, smooth, finely guttulate,

straight or gently curved if long and thin; basal conidia mostly narrowly cylindrical, but basal 2–3 conidia frequently obclavate, with an obconically truncate basal cell, 0–3-septate, 35–80 × 2.5–3.5(–5) μm; intercalary and terminal conidia subcylindrical to fusoid-ellipsoid, 0–3-septate, (22–)25–35(–43) × (2–)2.5(–3) μm; hila thickened and somewhat darkened, this website 0.5–1 μm. Culture characteristics: Colonies after 2 weeks on SNA slow growing, spreading with sparse aerial mycelium and somewhat feathery margin, reaching 6 mm diam; check details surface white to olivaceous-grey in colour. On PDA spreading with sparse aerial mycelium and somewhat feathery margin, reaching 7 mm diam; surface white with patches of olivaceous-grey, reverse cinnamon, Vorinostat with patches of olivaceous-grey. On MEA slower growing, erumpent, sparse aerial mycelium, even to somewhat feathery margin, reaching 6 mm diam after 2 weeks; surface white with olivaceous-grey patches, reverse olivaceous-grey. On OA spreading with sparse aerial mycelium and even margin, surface olivaceous-grey, reaching 7 mm diam; black erumpent sclerotia forming on all media. Appearance on apple: Compact speck consisting of shiny, black, flattened sclerotium-like

bodies, round to irregular (235–488 μm diam) appressed to the cuticle and less densely arranged (2–6/mm2) than S. henaniensis and S. pomigena. Specimens examined: TURKEY, Rize, Ardeşen, on fruit surface of a local apple cultivar, Nov. 2008, A. Karakaya, CBS H-20483 holotype, ex-type cultures CPC 18170 = T129A1c = CBS 128078; Rize, on fruit surface of apple cv. ‘Rize-Ardesen’, Nov. 2008, A. Karakaya, CPC 18169 = T114A1a2 = CBS 128079. Notes: Unique features of S. abundans include its abundant sclerotial formation, and its colonies, which are olivaceous-grey on all media studied. Phylogenetically, S. abundans and the morphologically similar S. asiminae are distinct, with 99% (585/593 bases) and 93% (427/463 bases) identity for ITS and TEF, respectively.
