Phaeoacremonium ovale

Ciri dan struktur

Sexual morph: Ascomata 225–300 μm (n = 5), on wood, perithecial, solitary, semi-immersed, unilocular, subglobose to globose, black, ostiolate, with ostiolar neck erumpent through bark of host when mature. Neck 445–645 × 35–45 μm (x̄ = 530 × 40 μm, n = 5), centrally ostiolate, contorted, lined with hyaline periphyses. Peridium 17–40 μm diam., membranous, composed of dark brown to hyaline cells of textura angularis. Hamathecium composed of 2–6 μm wide, hyaline, septate paraphyses, slightly constricted at septa and gradually narrowed towards apex. Asci 11–20 × 3–6 μm (x̄ = 15.5 × 5 μm, n = 30), 8-spored, unitunicate, clavate, with short pedicel, apically rounded. Ascospores 3–5 × 1.5–3 μm (x̄ = 3.5 × 2 μm, n = 50), bi-seriate, hyaline, oval to ellipsoid, aseptate, smooth-walled, rounded at the ends. Asexual morph: Mycelium on culture, partly superficial, composed of septate, branched, hyaline, rarely verrucose, hyphae 1.5–3 μm diam., rarely with adelophialides. Conidiophores usually arising from hyaline hyphae, mononematous, unbranched, occasionally constricted at basal septum, hyaline. Phialides 8–15 × 2–4 μm (x̄ = 9.5 × 3 μm, n = 20), terminal, monophialidic, elongate-ampulliform and attenuated at base. Conidia 2.5–6 × 1–2.5 µm (x̄ = 4 × 2 μm, n = 30), hyaline, ellipsoid to ovoid, aseptate. Ascospore germinating on PDA within 1 week at 23°C, germ tubes produced from ends. Colonies growing on PDA, reaching 2 cm diam. and sporulating after 30 days. Colonies semi-immersed to superficial, irregular in shape, flat, slightly raised, with undulate edge, slightly rough on surface, cottony to fairly fluffy, colony from above, greyish-brown (5F3–5, Ridgway 1912) at the margin, initially write to cream (5A1–3) in the centre, becoming dark brown (5F7–8) at the margin, orange-white (5B1–3) at the centre; from below, initially, greyish-brown at the margin, white at the centre, becoming dark brown at the margin, orange-white at the centre, producing brown pigmentation in agar.
