The cone carrots or nail sponges ( Strobilurus ) are a genus of fungi from the family of bark sponges . They form small fruiting bodies that often appear on cones of spruce or pine trees immediately after the snow has melted . The name Strobilurus given to this genus by Rolf Singer is derived from the Greek word for “cones” (=  strobilos ). The type species is Strobilurus conigenoides .

In the inconspicuous mushrooms, the substance class of strobilurins was discovered, which are effective fungicides . Strobilurin A and its synthetic derivatives achieved a market share of around 20 percent of the world fungicide market within a few years. Further strobilurins have also been discovered in other mushrooms.

features

Macroscopic features

The domed to flat spread hat, partly hunched in the middle, becomes 1–3 cm wide. Young fruiting bodies are gray-brown in color and later pale. The initially grayish, later white and sometimes yellowing lamellae are densely packed and bulge on the stem . The spore powder is white. The thin stem is first white and later colored ocher-brown except for the upper stem area.

Microscopic features

The elliptical spores are 4–5 micrometers long and 2.5–3 µm wide.

Generic delimitation

Other cone-dwelling fungi may look similar, especially the mouse- tailed mushroom ( Baeospora myosurus ) on pine or spruce cones and the spruce- cone helmling ( Mycena strobilicola ) on spruce cones.
