Eurasian beaver

Eurasian beaver (Castor fiber) is classified as Vulnerable (VU) on the IUCN Red List. Facing a high risk of endangerment in the wild, with declining populations and increasing habitat pressure.

Trichia contorta is a myxomycete producing clusters of small, cylindrical to pear-shaped sporangia on decaying wood, often in early succession on freshly fallen logs. It is distinguished by its twisted elaters, which are hygroscopic coiled threads within the sporangium that assist in spore dispersal. This species is found across temperate and boreal forests of the Northern Hemisphere.
