Fungi season is underway, marked by a surge of activity among mushroom enthusiasts and researchers alike. In North Wales, the annual fungus foray at Bangor University’s Treborth Botanic Garden showcased this year’s biodiversity with over 200 species identified in just an hour and a half. The event drew 225 participants, many of whom are seasoned foragers.
Among the notable finds was the orange ping-pong bat fungus (Favolaschia calocera), a striking species recently recorded in the United Kingdom for the first time in 2012. Its rapid global spread has been linked to climate change, underscoring shifting ecological patterns influencing fungal distribution.
On Anglesey (Ynys Môn), the island’s sand dunes—a key habitat for both conservation and ecological stability—have revealed an impressive variety of fungi despite their harsh, exposed conditions. At Aberffraw Dunes on the west coast, species such as parasols (Macrolepiota mastoidea) and champignon mushrooms (Marasmius oreades) have formed fairy rings visible among the dune landscape. In the damper depressions within the dunes, fibrecaps (Inocybe) and webcaps (Cortinarius) have also been found; these fungi are notable for their toxicity and their role in local ecosystems.
The dominant vegetation of the dunes, marram grass (Ammophila arenaria), is critical for stabilizing sand and sustaining dune profiles. Its underground stems track shifting sands, but the plant relies heavily on symbiotic fungi to extract nutrients from the nutrient-poor environment. Salt-tolerant dune brittlestems (Psathyrella ammophila) are found closely associated with marram grass. These fungi decompose dying roots, recycling nutrients back into the system and supporting new growth. Additional mycorrhizal fungi assist the plant by sourcing organic materials vital for its survival.
Recognition of fungi’s ecological importance continues to grow internationally. This year, the term “funga”—a counterpart to “flora” and “fauna”—has been incorporated into the Cambridge Dictionary and is set to be used by negotiators at the COP17 climate conference. This linguistic shift reflects increasing awareness of fungi’s integral role within ecosystems and their contribution to environmental health.
