You have to weather the attacks from the bushes but if you got the berries-seeds-gel then you get the gate way event which knocks you out and put a Mycus bush with fruit under you pick this to get Mycus Fruit then eat this to get the transcendence event eat more after to mutate(note that it is a low chance and also transcendence clears your genome any other mutations with go away and you will not be able to drink mutatgenic items so the trait genetic chaos/instability from the experiment/lab start is recommended). After you get the gate way event do note all nearby Mycus enemies will become friendly but you can still get the infestation from spores and spore clouds so stay with your safety gear till you get Mycus Identity or they will still ruin your day. Also something to note Mycus zombies and variants will still occasionally become hostile if you don’t have Mycus identity (they also attack fungaloids and other fungal entities and even with Mycus ID they will still target you(they can’t hurt you though). Also some modded fungal enemies aren’t effected by transcendence and Mycus identity one I recall is the fungal tender which I believe is from PK balancing.
