Spegazzinia deightonii

Ciri dan struktur

Saprobic on dead leaves of Musa sp. Sexual morph Undetermined. Asexual morph Hyphomycetous. Sporodochia powder like, dark, dense, dry, 1–3 mm diameter. Conidiophore mother cells 3.5–6.8 × 2.5–5.0 μm (x̄ = 5.59 × 4.15 μm, n = 6), hyaline to light brown, subspherical or doliiform. Conidiophores long or short and give rise to two types of conidia referred here as α and β. Conidiophores of α conidia up to 48–120 × 1–2 μm (x̄ = 95.3 × 1.6 μm, n = 20) long, erect or flexuous, narrow, verruculose, unbranched, hyaline to golden-brown. Conidiophores of β conidia initially hyaline, light brown to brown at maturity, very short and slightly bent, 1.6–2 × 2.5–3 μm (x̄ = 1.8 × 2.6 μm, n =10). Conidiogenous cell development basauxic, forming a single, terminal holoblastic conidium at the apex of conidiophore. Conidial development holoblastic. Conidia two types: α conidia stellate, 18–28 × 17–29 μm (x̄ = 25.1 × 23.3 μm, n = 25), solitary, globose to variously shaped, with spines 4–6 μm long, 4–8-celled, frequently 4- to 6-celled, deeply constricted at the septa. β conidia disc-shaped, initially hyaline, light brown to dark brown at maturity, 8-celled, 16–21 × 11–14 μm (x̄ = 19.2 × 14.6 μm, n = 25), flat from both sides with short and blunt spines, frequently with attached conidiogenous cells when splitting from the conidiophores. Conidia germinating on PDA within 13–14 h. Colonies growing on PDA, reaching a diameter of 55 mm after 14 d at 25 °C, raised, moderately dense, undulate margin, middle grey, periphery brownish grey and olive green at immature stage; reverse white to greyish white.
