Tarragon Oyster
A rare oyster mushroom of the British Isles named for its strong smell of tarragon. It was long treated as a variety of P. ostreatus, but phylogenetic work places it in the P. djamor-cornucopiae clade near P. citrinopileatus and P. cornucopiae. Hobbyists grow it, but it is not grown commercially.
Edible (Wikipedia). It closely resembles the oyster mushroom (P. ostreatus) and is told apart mainly by its tarragon smell and larger spores. The sources reviewed name no dangerous look-alikes, but any wild shelf-forming mushroom on wood should be identified with care.
Never eat a wild mushroom based on a web page — confirm with an expert.
