Fusarium longyuwanense

Ciri dan struktur

Mycelium not visible around ascomata or on host. Ascomata perithecial, crowded in group of 5 to 40, on basal stroma, oval, subglobose to globose, smooth, bright red when fresh, red brownish to dark red when dry, with a darker red ostiolar region, turning purple red in KOH and orange yellow in LA, 128–175 × 206–255 μm (n = 17). Perithecial wall consisting of a single layer, 15–25 μm thick, cells forming textura prismatica, 2–12 × 2–6 μm, walls 1–1.2 μm thick. Asci cylindrical, with a rounded apex, (4–7-)8-spored, 55–75 × 5–9 μm. Ascospores ellipsoidal to broadly ellipsoidal, equally 2-celled, slightly constricted at septum, smooth or finely verruculose, hyaline or pale brown, obliquely uniseriate in ascus often with ends overlapping, 7.5–12 × 4.5–5.5 μm. Colony on PDA 48 mm diam. after 7 d at 25 °C, surface cottony, aerial mycelium white, producing vinaceous pigment in medium. Colony on SNA 30 mm diam. after 7 d at 25 °C, surface slightly floccose, with sparse whitish aerial mycelium. Colony on CMD 56 mm diam. after 7 d at 25 °C, surface floccose, with sparse whitish aerial mycelium, producing vinaceous pigment in medium. Conidiophores with short simple branches. Conidiogenous cells monophialidic, cylindrical, tapering toward the tip, 12–63 × 1.5–3.5 μm. Conidia clavate, not in chains, hyaline, aseptate, 4–7 × 0.8–2 μm (n = 60). Macroconidia and chlamydospores not observed. Notes. Attempts were made to obtain macroconidia of the fungus in culture, but failed. Although the falcate macroconidia are lacking, the major phenotypic features of the fungus, such as occurrence on bark of Buxus sp., perithecia broadly ampulliform with a short neck, asci cylindrical with a rounded apex, ellipsoidal ascospores uniseptate and conidiophores monophialidic, fit well with the generic concept of Geejayessia.
