The Cranberry-Nacktbasidie ( Exobasidium oxycocci ) is a fungal art from the family of Nacktbasidienverwandten (Exobasidiaceae). It lives as an endoparasite on common cranberries ( Vaccinium oxycoccos ) and infects young shoots and leaves. The first symptoms of infestation by the cranberry naked basid are deformed pink leaves, followed by the appearance of white mycelium on the surface of the plant. The species has been found in Northern and Central Europe.

Macroscopic features
The cranberry basidia is initially invisible to the naked eye, the initial symptoms are the deformation and pink color of the leaves and shoots of the infected plant. The white mycelium of the fungus emerges later and covers the entire leaf or the entire shoot.
Microscopic features
The mycelium of the cranberry naked basid grows intercellularly and forms suction threads that grow into the storage tissue of the host. Basidia are formed either individually or in bushes between the cells of the plant epidermis. The basidia are long, unseptate and narrow-clumped, the spores hyaline and thin-walled.
distribution
In Europe, the spread of the cranberry naked basid is limited to Central and Northern Europe, it is linked to the occurrence of the common cranberry ( Vaccinium oxycoccos ).
ecology
The only host of the cranberry naked basid is the common cranberry. The fungus feeds on the nutrients present in the storage tissue of the plants; but limited to leaves and shoots when infected. The transmission from one plant to the next occurs through flight of spores.
