Hi: you can use sequencing for ITS reign . 

You can change the media . Potato dextrose agar could be helpful. You can find compendium of soil fungi for more details about this specie

Even in case it is acremonium-like fungus, then you are in trouble, since it is highly polyphyletic across ascomycetous group of fungi. For these sort of morphologies you need DNA information.

cheers, alex

PCR extraction and identification is the best in this case.

The last photograph to the right looks more like an Acrodontium
