UK Mushroom Sightings Expected to Reach Record Levels This Autumn

The Royal Horticultural Society (RHS) has predicted that mushroom sightings across the UK could reach record levels this autumn. According to the RHS, the combination of a prolonged hot, dry summer followed by wetter autumn weather has created conditions that may help certain fungi species flourish.

Jassy Drakulic, a senior plant pathologist at the RHS, noted that gardeners may observe a "remarkable variety of mushrooms and toadstools" appearing in lawns, borders, and near trees. The RHS reported a 43% increase in inquiries regarding garden fungi following the 2025 drought compared to the previous year. This growth is attributed to some species benefiting from the extra dead plant material left behind by drought, while others may produce more mushrooms in response to stress in trees. Experts characterize the presence of these fungi as generally indicative of a healthy ecosystem, as they play a role in breaking down organic matter and supporting plant health.

Foraging enthusiasts are also reporting shifts in local fungi populations. Colin Unsworth, a Lancashire-based forager who runs Forest Horizons, observed that while some species are appearing in "bumper" numbers—such as fly agaric and blushers—others have been more difficult to locate. For example, he noted that porcini mushrooms, also referred to as penny buns or ceps, have been "a bit thin on the ground" this year. Unsworth further highlighted a reported EU-wide shortage of these prized edible fungi.

While the autumn season provides opportunities to identify 20 to 30 edible types of mushroom on a typical forage, experts are emphasizing the risks associated with wild identification. Unsworth cautioned that some poisonous species, such as the brown roll-rim, can closely resemble edible varieties. He warned that individuals should not consume wild mushrooms unless they are entirely certain of their identification, as mistakes can be "really dangerous."
