Devil'S Urn
urnula craterium
The Devil's Urn (Urnula craterium) is a fascinating early spring fungus easily recognized by its distinctive, dark, cup-like appearance. Resembling a charred, leathery goblet sprouting from the forest floor, it is often one of the first macrofungi to emerge after the snow melts. For avid mushroom foragers, spotting a Devil's Urn is a moment of excitement, as it acts as a classic phenological indicator that the prized morel mushroom season is just around the corner. Ecologically, this fungus lives a double life. It begins as a weak parasite on living oak trees, causing a disease known as Strumella canker, before transitioning into a saprobe that feeds on the dead, decaying hardwood. Its striking appearance and unique life cycle make it a captivating find for nature enthusiasts exploring early spring woodlands.
Hábitat: Found in temperate hardwood forests, particularly on or near decaying oak logs, buried branches, and fallen timber.
Aspecto
The Devil's Urn forms a deep, cup-shaped or urn-like fruiting body that typically measures 4 to 8 centimeters in height and 3 to 4 centimeters wide. Its exterior is dark brownish-black with a slightly fuzzy or scaly texture, while the spore-bearing interior surface is smooth and jet black. As the fungus matures, the rim of the cup often splits, tearing into ragged, star-like margins. It is attached to the substrate by a short, tough, and sometimes buried stalk, giving it the appearance of a dark chalice resting directly on the leaf litter.

Datos interesantes
Despite its eerie name and black, charred appearance, the fungus is entirely harmless to humans, though it is considered inedible due to its tough, leathery texture.
Foraging enthusiasts often affectionately call the Devil's Urn a 'morel indicator' because its appearance signals that prized morel mushrooms will soon begin to fruit.
If you gently blow on a mature Devil's Urn, the change in air flow can trigger the fungus to release a visible, smoke-like puff of spores.
It causes a disease called Strumella canker in living oak trees, which produces a distinctive target-shaped wound on the tree's bark.
Habilidades especiales
Habilidad
Spore Puffing
When exposed to a sudden change in air pressure or a gust of wind, the mature cup can forcibly eject its spores in a visible cloud resembling smoke.
Habilidad
Cryotolerance
Fruiting in early spring, this tough fungus can survive sudden frosts and freezes, pausing its growth until temperatures rise again.
Habilidad
Biphasic Lifestyle
It seamlessly switches between a parasitic phase on living trees to a saprobic phase decomposing the very same wood once it dies.
