Extract from Wikipedia article: Tricholoma terreum, commonly known as the grey knight or dirty tricholoma, is a grey-capped mushroom of the large genus Tricholoma. It is found in coniferous woodlands in Europe, and has also been encountered under introduced pine trees in Australia. It is regarded as edible. A 2014 article speculated that it may be poisonous, but Sitta et al. in 2016 published in the same journal a counter article demonstrating the unfounded nature of such speculation.
