Sorry, I don't have a microscopic data for this strain. There are no microscopes available in the laboratory. That's the reason I couldn't identify the strain.
For identifying fungi based on colony morphology, we need to grow at least on three agars - CYA, MEA and YES agars. Just by seeing this image, I feel it can be some aspergillus species. Good luck
You should prepare wet mounts of your fungal culture in Narayan stain or PHOL stain to see the detailed morphology. Both the stains are developed by us for studying the morphology of fungi isolated from clinical as well as environmental sources. One can isolate such filamentous fungi from saprobic environment. I believe that microscopic morphology may help you to identify this saprobic mold.
