Oyster Mushroom vs Deadly Galerina in Maine: Field Identification
Oyster mushrooms should only be called when cap texture, lateral growth, and gill structure all agree. The fastest separation comes from the visible field marks you can confirm before you pocket or collect anything. Maine context matters because Oyster Mushroom (Pleurotus ostreatus) is a realistic state-level profile for Maine, where foragers look for it in dead hardwood trunks, especially beech, aspen, cottonwood, and maple tied to maple-beech forests, birch groves, and coastal spruce woods.
Safety note: Deadly galerina contains amatoxins, so wood-growing mushrooms demand strict cap, gill, and spore-print discipline.

Key Differences
Oysters are larger, shelf-like, and lateral on wood, while galerina tends to be smaller, stemmed, and brown-spored.
The fastest separation comes from the visible field marks you can confirm before you pocket or collect anything.
In Maine, the site context and seasonal window often tell you which side of this comparison is more realistic before you ever handle the specimen.
