摘要: A Fusarium species with a micro morphology similar to F. poae and metabolite profile resembling that of sporotrichioides has been identified. Like typical poae, the microconidia have globose pyriform shape, but powdery appearance, especially on Czapek-Dox Iprodione Dichloran agar (CZID), less aerial mycelium lack fruity odour Potato Sucrose Agar (PSA) make it different from poae. The macroconidia, polyphialides chlamydospores differentiates sporotrichioides. All 18 isolates investigated, 15 Norwegian, two Austrian one Dutch, produced T-2 toxin (25-400 micrograms/g) PSA or Yeast Extract (YES). In addition, neosolaniol, iso-neosolaniol, HT-2 toxin, 4- 15-acetyl tetraol, triol tetraol 4,15-diacetoxyscirpenol were formed in variable amounts. Neither nivalenol, 15-acetylnivalenol 4,15-diacetylnivalenol detected any cultures, while these toxins at least small amounts by all 12 studied. question whether this should be classified as separate taxon addressed.
