Fusarium andiyazi sp nov., a new species from sorghum

We describe anew Fusarium species in section Liseola from sorghum in Africa and the United States. This species is distinguished morphologically by the production of unique pseudochlamydospores in carnation leaf pieces on carnation leaf agar, and appears to be most closely related to F. thapsinum. The new species also can be distinguished molecularly by means of Amplified Fragment Length Polymorphisms, AFLPs. Strains with both MAT-1 and MAT-2 mating types were identified, but no sexual stage was generated in crosses made under laboratory conditions.
