Description

The characters of pathogenic fungi on the leaves were identified through an artificial infection test. Asexual morph: Conidiomata white, scattered, hairy. Conidiophores straight to flexuous, consisting of a stipe bearing a penicillate arrangement of fertile branches, stipe septate, hyaline, smooth; stipe extensions septate, straight or curved, dull and tapering towards the apex, 128.5-549.9 µm long, (x̄= 288.1 µm, n = 20). The primary branches of conidiogenous apparatus aseptate, 9.3-17.5 × 2.6-3.7 μm; secondary branches aseptate, 9.9-19.1 × 2.5-3.9 μm; tertiary branches aseptate, 9.5-17.6 × 2.6-3.7 μm; quaternary and additional branches (-6) aseptate, 11-16.3 × 2.5-3.9 μm, each terminal branch producing 2-4 phialides; phialides doliiform to reniform, hyaline, aseptate, apex with minute periclinal thickening and inconspicuous collarette. Conidia cylindrical, rounded at both ends, straight, 1-septate, hyaline, (30.5-) 31.2-37.2 (-42.0) × (2.6-) 2.9-3.5 (-3.9) µm, (x̄= 34.2 × 3.2 µm, n = 20) (Fig. 1 View Figure 1 ). Sexual morph: not observed.

The characters of fungus obtained from the diseased leaves collected in the field that were cultured with PDA: after 10 days at 25°C on PDA, colonies reached 47 mm in diam. Beige to pale yellow colony on the surface, brown in reverse with irregular margins, extensive sporulation on the medium surface. Conidiophores straight to flexuous, consisting of a stipe bearing a penicillate arrangement of fertile branches, stipe extensions septate, straight or slightly flexuous, 104.4-153.0 µm long, (x̄= 128.7 µm, n = 10). The primary branches of conidiogenous apparatus aseptate, 8.9-17.8 × 2.7-3.4 μm; secondary branches aseptate, 7.8-14.0 × 2.5-5.9 μm; tertiary branches aseptate, 8.9-17.7 × 2.3-3.5 μm; quaternary and additional branches (-6) aseptate, 9.3-16.7 × 2.3-3.7 μm, each terminal branch producing 2-4 phialides; phialides doliiform to reniform, hyaline, aseptate, apex with minute periclinal thickening and inconspicuous collarette. Conidia cylindrical, rounded at both ends, straight, 1-septate, hyaline, (38.5-) 45.2-56.6 (-63.2) × (2.2-) 2.9-4.2 (-4.9) µm, (x̄= 50.9 × 3.5 µm, n = 40). Chlamydospores thick-walled, ellipsoidal or sphaeropedunculate, brown to hyaline, (9.0-) 11.9-20.7 (-23.1) × (8.1-) 8.9-12.8 (-15.4) µm, (x̄= 16.3 × 10.8 µm, n = 20) (Fig. 2 View Figure 2 ).
