Fungi are integral parts of terrestrial ecosystems. Sporocarps propagate by spreading their spores from fruiting bodies. Their fruiting bodies are looked for both by foragers and conservationists. Potential changes to spore production and the timing of fruit body production could be useful information for both foragers and conservationists. This report uses e-DNA from air filters gathered from Kiruna in northern Sweden to measure shifts in the spore-producing period of the fungal genera Boletus, Morchella, Coprinus, Cantharellus, Hydnellum, and Ramaria, both in terms of amount of spores released and timing of fruit body formation. The start week, peak week of sporulation, estimation of seasonal end, and cumulative sum of spores released for each genus were calculated and then correlated against each other. The relationship between these variables and the climatic variables of temperature and precipitation, both for the current year and previous year were also calculated. The report found no significant trends in the timing of the start of sporulation, but spore production for both Morchella and Ramaria increased along the timeseries. The report found an overall positive response to increases in precipitation and temperature for the studied genera, with the exception of Boletus, indicating that climate change is unlikely to negatively impact these genera in northern Sweden.
