The Rotfleckende Cranberry Nacktbasidie ( Exobasidium rostrupii ) is a fungal art from the family of Nacktbasidienverwandten (Exobasidiaceae). It lives as an endoparasite on common cranberries ( Vaccinium oxycoccos ) and infects their leaves. The first symptoms of infestation by the red-spotted cranberry bare-bones are small red spots on the upper side of the leaf, followed by the appearance of the white mycelium on the underside of the leaf. The species has been found in Northern, Northwestern and Central Europe.

Macroscopic features
The red-spotted cranberry basidia is initially invisible to the naked eye, the initial symptom of the infestation is the appearance of small red spots on the upper side of the leaf of the infected plant. The mycelium of the fungus later emerges on the underside of the leaf and becomes visible there as a thin, whitish carpet.
Microscopic features
The mycelium of the red-spotted cranberry nudibranch grows intercellularly and forms suction threads that grow into the host's storage tissue. Basidia are formed either individually or in clusters 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 distribution of the red-spotted cranberry naked basid is limited to Central, Northwestern and Northern Europe, it is linked to the occurrence of the common cranberry ( Vaccinium oxycoccos ).
ecology
The only host of the red-spotted cranberry naked basid is the common cranberry. The fungus feeds on the nutrients present in the storage tissue of the plants; but limited to the leaves when infected. The transmission from one plant to the next occurs through flight of spores.
