Colony and micro-morphology features of two fungal isolates at 400x magnification. (a) NK-NH1. Scale bar is 10 μm. (b) NK-NH2. Scale bar is 10 μm. (c) Neighbour-joining phylogenetic tree of Fusarium sp. NK-NH1 and Fusarium sp. NK-NH2 ITS gene sequences (~520–540 bp sequence used for each). Representatives of the most closely related strains and additional members of the genus Fusarium are included for taxonomic context. Bootstrap values at nodes are given as a percentage of 1000 bootstrap replicates. Scale bar indicates the expected number of substitutions/site.
