The Großsporige noise Beer Nacktbasidie ( Exobasidium vaccinii-uliginosi ) is a fungal art from the family of Nacktbasidienverwandten (Exobasidiaceae). It lives as an endoparasite on wild berries ( Vaccinium uliginosum ) and infects their annual shoots. The symptom of an infestation by the thick-pored bogberry naked basid is the appearance of the white mycelium on the plant surface. The species has been found in Northern and Central Europe.

Macroscopic features
The large-spore bogberry bare-bones cannot be seen with the naked eye until the whitish mycelium emerges on the underside of annual shoots and later covers the entire underside of the leaf.
Microscopic features
The mycelium of the large-spore bogberry bare-bones grows intercellularly and forms suction threads that grow into the host's storage tissue. 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. The spores are usually 16–23 × 6–9 µm in size, and their dimensions are a good way of distinguishing them from other bogberry nude basidia.
distribution
In Europe, the distribution of the large-spore bogberry bare-bones includes the arctic ( Greenland , Iceland ) as well as subalpine and alpine regions.
ecology
The only known host of the large-spore Rauschbeer-Nacktbasidie is the bilberry. The fungus feeds on the nutrients present in the storage tissue of the plants, initially limited to the leaves and then on the entire plant. The transmission from one plant to the next occurs through flight of spores. The spores germinate in germ tubes or conidia , from which a new mycelium then develops.
