Scientists created a detailed genetic blueprint of the angel-wing mushroom, which caused serious poisonings in Japan. They identified three toxic compounds in the mushroom and found a gene that likely produces one of the most dangerous toxins responsible for brain damage. This research helps explain how the mushroom makes its poison and could lead to better understanding of foodborne illness prevention.

Scientists discovered a new type of mushroom in northwestern China’s coniferous forests and named it Neotricholomopsis globispora. Using DNA analysis and microscopic examination, they determined this mushroom belongs to a previously unknown genus within the Phyllotopsidaceae family. The mushroom is characterized by its nearly white to buff cap with coral-red scales and a distinctive ring-like zone on the stem. Based on genetic analysis, researchers estimated this mushroom genus first appeared roughly 229 million years ago during the late Triassic period.
