Fusarium culmorum sporodochia on carnation leaf on CLA.
Please note that macroscopic photographs of Fusarium colonies grown on CLA have limited diagnostic value. CLA is mainly used to promote sporulation and facilitate the observation of microscopic structures. At the colony level, many Fusarium species appear very similar, typically showing white to cream or pale pink colonies, sparse aerial mycelium, relatively slow growth, and salmon-colored sporodochia. These macroscopic traits are often too variable and overlapping to allow reliable species identification.
Growth time:
3
Lighting:
Darkness and supplementary NUV at 360nm to encourage sporulation
Agar:
CLA (Oxoid Technical agar no3 with carnation leaves)
Agar brand:
Oxoid
Sample origin:
United Kingdom of Great Britain and Northern Ireland
