What is the difference between sapphire fungi and parasites?

Parasitic fungi are fungi that use other living organisms as a source of food and habitat. The host organism suffers from the activity of the parasite, which can lead to his illness or death.

Saprophytic mushrooms are mushrooms that extract the substances they need from dead organisms. Roughly speaking, when compared with the animal kingdom, they are scavengers. They can use leaves, branches, trunks, humus, manure, bird feathers and so on as a source of food.
