Hypoxylon crocopeplum

Ciri dan struktur

Stromata superficial, effused-pulvinate, up to 8 cm long × 0.4–2 cm wide, with conspicuous perithecial mounds; surface Orange (7), Sienna (8), Apricot (42) in young stromata, Bay (6) to Sepia (63) in mature stromata; orange red granules immediately beneath surface and between perithecia, with KOH-extractable pigments Orange (7). Perithecia obovoid to slightly tubular, 0.2–0.5 mm high × 0.2–0.4 mm wide. Ostioles lower than or at the same level as the stromatal surface. Asci 8-spored, cylindrical, with discoid apical apparatus lightly bluing or bluing in Melzer’s iodine reagent, 0.5–1 µm high × 2–2.5 µm wide, stipe up to 100 µm, and spore-bearing portion 70–96 × 7–9 µm. Ascospores smooth, unicellular, brown to dark brown, ellipsoid-inequilateral, with narrowly rounded ends, 11–15(–15.8) × 5–6.8 µm, with straight to slightly sigmoid germ slit spore-length on convex side; perispore dehiscent in 10% KOH, inconspicuously to conspicuously striated; epispore smooth. With thin, effused, dull orange-brown stromata, orange-yellow stromatal pigments, and dense orange KOH-extractable pigments, combined with dark brown inequilateral ascospores with a straight germ slit, this Hypoxylon specimen keys out to H. crocopeplum or H. subgilvum. H. crocopeplum differs from the latter by the ostioles being lower than or at the same level as the stromatal surface vs. ostioles umbilicate and inconspicuous, the size of ascospores [(13.4–)13.8–17.1(–17.5) × (7.1–)7.3–8.3(–8.6) vs. (8.9–)9.1–9.9(–10.6) × (4.2–)4.5–5.0(–5.1) μm], and the anamorphic structure [a virgariella-like conidiogenous structure was observed in culture on YMG (unpublished data) and on JF-03233, vs. on the natural substrate with a virgariella- to nodulisporium-like conidiogenous structure, in culture on OA nodulisporium-like] (Fournier et al. 2015).
