Colletotrichum siamense

Ciri dan struktur

Associated with leaf spots of Nypa fruticans. Leaf spots initially small, round, necrotic, then expand and elongate and turn irregularly round, brown with a darker brown margin. Asexual morph: On PDA, conidiomata pycnidial, solitary, black, sub-globose to globose, semi-submerged, bearing orange conidial masses. Conidia 9.1–13.1 × 3–4.4 μm (11.5 ± 1.1 × 3.9 ± 0.4 μm, n = 30), aseptate, hyaline, smooth, uni- to biguttulate, round to cylindrical, apex subrounded to rounded. Conidiophores hyaline, septate, unbranched, cylindrical to inflated, straight or slightly curved, tapering towards the apex. Conidiogenous cells are cylindrical to round, hyaline, smooth, and thin-walled. Setae light to dark brown, concoloured, smooth-walled to finely verruculose, 2–4-septate, 58.4–79.2, (69.8 μm ± 6.4, n = 10) long, some much longer than others. Base constricted, slightly swollen above the constriction, or cylindrical, tip slightly acute. Sexual morph: Not observed. Colonies on PDA media, reaching 44.5 mm, when incubated at room temperatures (28 ± 2 °C) for 7 days, produce different morphotypes: a) gray center and white at margin, raised colonies with abundant aerial mycelium and spore masses around the colony. The reverse is grayish and white. b) all white slightly raised colonies, dense, cottony with floccose aerial mycelium and yellowish reverse; c) grayish-white to dull olivaceous, flat colony with sparse aerial mycelium and scattered dark patches and dark gray and white reverse.
