Appeared after 24 hrs of culturing fresh human bone marrow in DMEM provided with 10% FBS in 40 ml T-flask , what is that and how to get rid of if it affected the incubator ?

2 jpg's of unknown mag - are these photomicrographs or pictures of mucoid colonies? And one poor out-of-focus photomicrograph of unknown mag. None of these indicates a fungal contaminant. Suggest you address conventional microbiological procedures.
