Thanks Lance, God, I'm glad it's not Erwinia! My beloved Delrosi.
By the way, should I still keep it closer to the fan, or will that spread the pores around more? Does fungus dislike more air movement?
Fungus grows best in still stagnant air conditions so increasing the air movement will help do prevent the fungal conditions.
Some fungus disperse spores through water and not air. This is probably the case with what your plant has.
If you are not seeing this spread to other plants in the amount of time you have had the plant then it may not be very contagious. It may very well be the result of this plant having some metabolic condition that encourages the fungal growth. This is exactly the type of infection that excesses of certain nutrients may cause to manifest.
