Helvella solitaria

Helvella solitaria is a species of fungus in the family Helvellaceae. It produces cup-shaped fruiting bodies with dark brown to black spore-bearing surfaces supported by ribbed, whitish stalks. First described by the Finnish mycologist Petter Adolf Karsten in 1871, the species is distinguished by its hollow stipe with three to six blunt ribs that continue onto the cup's base and its ellipsoid-shaped spores containing a single oil droplet. The fungus has a boreal and temperate distribution across Europe and North America, occurring in both coniferous and mixed forests from sea level to alpine elevations of about 2,400 metres (7,900 ft). It typically grows on mineral-rich soils in various habitats, including beneath shrubs, in dryas-dominated fellfields, along grassy verges, and on roadside substrates under trembling aspen....read more on Wikipedia.
