If you have access to DNA sequencing facilities you may amplify the standrd region between ribosomal 18 and 23 S and send it out for sequencing; the data you will obtain provide you with the species name, or nearest hit.
How wonderful it would be if we could identify species by merely looking at its morphology. Please do the %s rDNA partial sequencing and then do one-to-one local alignment.
I suppose its Fusarium spp. From which specimen did you grow this? Still you can go for molecular confirmation. Also can you show the reverse of the agar slant to see any pigment production?
