The cloudy funnel is a prominent and easily recognisable fungus that has established itself as a common feature in New Zealand's varied forest environments. It is named for its distinctive, funnel-shaped cap, which typically exhibits a muted, greyish-brown or cloudy colour, often appearing somewhat smoky or frosted in appearance. The cap can grow to a significant size, ranging from 5 to 20 centimetres in diameter, and it is usually smooth to the touch. As the mushroom ages, the cap margin may flatten or become slightly undulating, but it often retains its characteristic funnel-like depression at the centre. Beneath the cap, the gills are narrow, crowded, and run decurrently down the stem, meaning they extend slightly onto the stipe. The stem itself is robust, firm, and usually paler than the cap, often tapering towards the top. When fresh, the fungus has a distinct, somewhat pungent or perfumed odour that can be quite noticeable to passersby in the woods. Ecologically, the cloudy funnel acts as a dedicated saprotroph, performing the essential task of decomposing organic material on the forest floor. It thrives on thick layers of decaying leaf litter, woody debris, and compost, which are common in both dense native bush and managed plantations or gardens. By breaking down tough plant matter, it returns critical nutrients to the soil, supporting the growth of surrounding plants and trees. Unlike many other forest fungi, it is known for its tendency to grow in large groups, often forming expansive fairy rings that can persist for years. These rings are created as the mycelium spreads outward from a central point, exhausting nutrients in the inner zones while fruiting at the nutrient-rich perimeter. This growth habit makes it a striking sight during the cooler, wetter months when it produces its numerous fruit bodies. While the cloudy funnel is often cited in older field guides as an edible mushroom, modern mycological consensus advises caution. Many individuals experience severe gastrointestinal distress or allergic reactions after consuming it, and there is evidence to suggest that it may be toxic to a subset of the population. Consequently, it is generally recommended that it be left for observation rather than harvested for the table. Its role as a forest recycler is far more significant, providing a vital service that keeps the ecosystem balanced and productive. For walkers and naturalists, it remains a common and interesting subject, readily identified by its grey colour, large size, and habit of forming clusters in damp, shady areas of the landscape.
