Every month, museum visitors choose the exhibit they liked the most. What made the visitors stand out for the month of May was a bright mushroom, Renati's Mycena (Mycena renati Quél). This common but inedible mushroom is thought to have been named after the prehistoric Greek city of Mycenae. The French mycologist Lucien Rene Quélet was the first to mention it in 1886. It is usually found in groups on the wood - in decay - of broad-leaved trees. Its odor is reminiscent of bleach and its taste is mild.
