Aspergillus faecalis:
The diameter of colonies cultured on Xiakeqiong lipid at 25℃ for 7 days is 30-40mm, and the diameter of colonies cultured on Xiakeqiong lipid at 25℃ for 7 days is 12- 14 days is 50-70mm, which is white at first and flocculent in texture, and then forms conidia structure. Cultured on Charcot yeast extract agar at 25℃ for 7 days, the colony diameter was 45-65 mm, 12-65438+. At first, it was white, with less conidia structure, and the color was the same as that on Chakeqiong grease.
Extended material:
The colony diameter of Chakeqiong fat cultured at 25℃ for 7 days was 30-40mm, and the colony diameter of 12- 14 days was 50-70mm, which was white at first and flocculent in texture, and then formed conidia structure, which was more or less yellow-brown, close to Oliveyeelow-ecruoolive (r.xxx).
Sclerotinia, large, scattered or concentrated in the central part of the colony, first white, then black, often accompanied by exudate; The reverse of the colony is colorless to yellowish. The conidia head is spherical to radial at first, with a diameter of 50- 150mm, and then becomes a dense column with a slightly wider top, and sometimes the top and bottom are slightly wider, (125-) 250-600 μ m× 75-200 μ m. ..
Conidiophore is produced from substrate or aerial mycelium, and the stalk length of spore stalk varies greatly, from (140-) 500-1200 (-2000) μ m× (5-) 8-12 μ m, slightly curved near the apical sac, with smooth or rough wall, and in a dry state. The apical capsule is spherical or nearly spherical, (12-)25-43(-50) microns, and 2/3 of its surface is fertile.
The sporulation structure has two layers: pedicel base 6- 1.4 μ m× 3.2-4.8 μ m, pedicel 5- 1.0 μ m× 2-3 μ m, and only pedicel occasionally grows on small apical sac; The conidia are spherical to nearly spherical, with a diameter of 3-4μm, a smooth or slightly rough wall, a long chain of conidia, which are not easy to fall off and have obvious interspore connections. Spherical and nearly spherical sclerotia are generally 840- 1500μm, and long sclerotia can reach1500-3000 μ m×1000-1500 μ m and stand upright.
