Entoloma rhodopolium, commonly known as the wood pinkgill, is a poisonous mushroom found in Europe and Asia. In fact, it is one of the three most commonly implicated fungi in cases of mushroom poisoning in Japan (Other two are Omphalotus japonicus and Tricholoma ustale). E. rhodopolium is often mistaken for edible mushroom, E. sarcopum. Symptoms are predominantly gastrointestinal in nature, though muscarine, muscaridine, and choline have been isolated as toxic agents. Entoloma nidorosum, previously considered a separate species, is now classified as a variety of this fungus.
