The Royal Horticultural Society (RHS) has predicted that mushroom sightings across the UK could reach record levels this autumn. This follows a period of drought and subsequent wetter weather, which the RHS suggests could help some fungi species flourish.
Colin Unsworth, a forager in Lancashire, noted that some species, including fly agaric and blushers, have appeared in "bumper" numbers. However, he also observed that porcini mushrooms have been "a bit thin on the ground." Unsworth cautioned against eating wild mushrooms unless identification is certain, as some poisonous varieties closely resemble edible ones, such as the brown roll-rim.
Jassy Drakulic, RHS senior plant pathologist, stated that gardeners might observe a "remarkable variety of mushrooms and toadstools" in their lawns, borders, and around trees this autumn. She added that fungi generally indicate a healthy ecosystem, aiding in the breakdown of organic matter and supporting plant health. The RHS advice team recorded a 43% rise in inquiries about garden fungi after the 2025 drought, compared to the previous year.
