Bonus flush of Pleurotus ostreatus mushrooms from the buckets I started many months ago.
I moved these buckets outside after two flushes & removed the lids to allow the late-winter rains to rehydrate the substrate.
It's hard to tell from this photo but the attachment points of these clusters are between the bucket & the substrate (below the top surface).
Mushrooms often form at the interface between zones. In this case, a moist area at the edge of the substrate & close to open-air.
Merveilles is a community project aimed at the establishment of new ways of speaking, seeing and organizing information — A culture that seeks augmentation through the arts of engineering and design. A warm welcome to any like-minded people who feel these ideals resonate with them.
