says Wallemia sebi common on “high sugar or salt” substrates. Neither is common in coffee grounds …

P.o. can have many colors in the mycelium. Coffee grounds can change the “typical” color of P.O. mycelium. However, the spores are omnipresent in PNW, and it is possible.

As for Wallemia sebi … I have not heard of this fungus before. I kind of think it would have been reported by this time, though. Time to research.

It would be really cool if this were Pleurotus ostreatus, and I have grown this species in my home and brought home collections from the wild. However, I doubt it is because of the colors of this fungi. I believe it may be two or more molds.

Maybe Wallemia sebi is one of them.

could this be Wallemia sebi?

white wood-rotting fungi will also grow on coffee beans or coffee bean grounds. May be Pleurotus ostreatus as it grows rapidly on that substrate. But for definitive work, will have to fruit it. Got more coffee grounds?
