Strobilurus tenacellus, commonly known as the pinecone cap, is a species of agaric fungus in the family Physalacriaceae. It is found in Asia and Europe, where it grows on the fallen cones of pine and spruce trees. The fruit bodies (mushrooms) are small, with convex to flat, reddish to brownish caps up to 15 mm (0.6 in) in diameter, set atop thin cylindrical stems up to 4–7.5 cm (1.6–3.0 in) long with a rooting base. A characteristic microscopic feature of the mushroom is the sharp, thin-walled cystidia found on the stipe, gills, and cap. The mushrooms, sometimes described as edible, are too small to be of culinary interest. The fungus releases compounds called strobilurins that suppress the growth and development of other fungi. Derivatives of these compounds are used as an important class of agricultural fungicides.
The species was first described as Agaricus tenacellus by Christian Hendrik Persoon in his 1796 Observationes Mycologicae. In its taxonomic history, it has been moved to the genera Collybia by Paul Kummer in 1803, Marasmius by Jules Favre in 1939, and Pseudohiatula by Georges Métrod in 1952. Rolf Singer transferred it to the newly circumscribed genus Strobilurus in 1962, giving it the name by which it is currently known.
