Scientists developed a practical method to extract high-quality DNA from mushrooms collected in the wild, even in remote locations without refrigeration. The technique involves preserving fresh samples in alcohol and then carefully purifying the DNA through multiple steps. This method successfully produced DNA suitable for reading the complete genetic code of 23 different fungal species, particularly those that cannot be grown in laboratories.

Discovery of two new Cortinarius species in Southern China

Scientists discovered two new species of mushrooms in Fujian Province, China, called Cortinarius griseoaurantinus and Cortinarius yonganensis. Using DNA analysis and microscopic examination, they confirmed these are distinct species and described their unique characteristics, including their colorful caps and spore structures. Some Cortinarius mushrooms contain helpful compounds for dyes and medical research, but others can be toxic, making accurate species identification important.

Scientists developed a practical method to extract high-quality DNA from mushrooms found in nature, which is essential for understanding fungal genomes. The technique works without needing freezers or ice by preserving tissue in alcohol at room temperature. The method successfully extracted usable DNA from 33 different mushroom species, including rare species that cannot be grown in laboratories, enabling researchers to sequence and study their complete genomes.
