Alternaria eureka

Ciri dan struktur

Colonies on PCA velvety to cottony colonies, mostly mycelial, subhyaline, loosely wooly, reaching 75 mm in diameter after 7 days; meager sporulation or lacking until hyphae are disturbed or scarified. Conidiophores emerging from the surface of agar or aerial vegetative hyphae scattered or clustered on cut agar in light-exposed areas. Primary conidiophores mostly simple, rarely branched, 25–75 × 5–6 µm, geniculate with 2–3(–4) conidiogenous loci. Secondary conidiophores, short, 3–7 × 3 µm, 1–2-celled, formed apically or sometimes laterally from primary conidia, mainly with one conidiogenous locus. Further geniculate extensions and conidium production yield several clusters of sporulation at the colony center. Sporulation pattern in single clumps of a few short branching chains consisting of 5–7 conidia. A high percentage of conidia solitary at any age of growth. Conidia ellipsoid to ovoid, with a rounded base and tapered apex; multiple transverse and longitudinal septa, conspicuously constricted near 2 or 3 transverse septa, in short chains. Mature conidia with 2–3 transverse septa and 0–3 longitudinal septa located mainly at the center of the colony, 20–24 × 8–15 µm; slightly older conidia, 25–34(–48) × 11–16 (–22) µm with 3–4(–5) transverse septa and 1–3 oblique or longitudinal septa. Conidial body color brown with relatively dark and thick transverse septa (Fig. 2A, B); the outer wall smooth or punctate. Formation of protoascomata and chlamydospores in the surface of vegetative mycelium conspicuous after 2–3 weeks of incubation. Chlamydospores hyaline, spherical or ovoid, terminal, sub-terminal or intercalary, measuring 13.5–22.5 × 10–15 µm, mostly single-celled (Fig. 2C).
