Alternaria hungarica

Ciri dan struktur

Colonies on PCA velvety, approximately 70 mm in diameter, with three discrete concentric rings of growth after 7 days. Aerial axes abundant and reaching a size length of 113–387 µm, with 5 to 10 lateral conidiogenous branches and tips in light-exposed zones of young parts of the colony (Fig. 3A). These branches most frequently on the upper portions of aerial conidiogenous elements, forming an arachnoid layer of branching hyphae. Primary conidiophores formed outside the center of the colony, simple, rarely branched, produced at the substrate surface, conspicuous, straight, or geniculate, up to 30–110(–352) × 3.8–5 µm, often developing through geniculate extensions. Each conidiophore bearing 1–3 conidia, sometimes with additional short chains of 2–3 conidia through secondary conidiophores formed mainly from distal terminal conidial cells (Fig. 3B). Secondary conidiophores short, 20–52(–105) × 3–5 µm, with one or two conidiogenous sites. A high percentage of conidia of any age remaining solitary. The sporulation patterns in small clumps on elongate-branched sporulating hyphae forming a brown layer at the center of the colony. Conidia medium brown to brown, short ellipsoid, ovoid, muriform, mainly beakless or with a rounded apex (Fig. 3B). Dominant size range: 22–37(–40) µm long × 13–20 μm width with 2–4(–5) transverse septa and 0–2(–3) longitudinal septa in each of the transverse segments. In the center of the colony, a high percentage of dark pigmented conidia mature of smaller size, 17.5–25 × 12–17.5 µm, initiating chain development. All maturing conidia distinctly constricted at their transverse septa, developing thick and dark-brown pigmented outer walls and sometimes with a punctate surface.
