I think that these will be fibromas, likely caused by a papillomavirus, but could also be caused by a poxvirus.

Exactly which papillomavirus or poxvirus is dependent on the particular species of deer infected, as these viruses are often species-specific.

There are some resources about the diseases at Maine.gov and at the National Deer Association
