Fungal issues often complicate Morgellons, mites, and other skin parasites. When it comes to skin fungus, the references are rather weird. If you Google skin fungus, you generally find articles like at Web MD that are limited to yeast infections (Candida), athletes foot, jock itch, and ring worm. And of course, we have nail fungus and toe nail fungus . However, if you Google Images for skin fungus, you find images of fungus growing in all areas of the body--some look like ring worm, many don't. And then there are other serious fungal infections like Blastomycosis which is when dangerous fungal spores get into the lung. It can be deadly.
There are three ways of dealing with skin fungus and Candida internally. One is lufenuron which also helps with mites. If you go that route, give them my name when you order to obtain faster service. The second is Ketocanazole cream and other anti fungal meds are also externally used for various skin fungus.
The other is apple cider vinegar which I highly recommend as the disinfectant for skin fungal issues. Generally, the less expensive apple cider vinegar you find in the grocery store is sufficient in the bath, however, for internal use for Candida, you will want to consider a better quality of apple cider vinegar that has the mother in it as well as described in the article titled, Tips for Using Apple Cider Vinegar for Chronic Yeast Overgrowth.
However, if you're dealing with Collembola and are in the early stages of the King Diet (in my book--How to Get Your Life Back from Morgellons...), the apple cider vinegar will probably feed the Collembola which limits you to lufenuron and the King Diet™. And, remember, Stage I of the King Diet™ is the best anti Candida diet you can find.
For nail and toe nail fungus, we have debriding soap Nail and Toe Nail Fungus Cleanse to deep clean plus apple cider vinegar in a foot or hand bath..
