The Dicksporige noise Beer Nacktbasidie ( Exobasidium pachysporum ) is a fungal art from the family of Nacktbasidienverwandten (Exobasidiaceae). It lives as an endoparasite on wild berries ( Vaccinium uliginosum ) and infects their leaves. Symptoms of the infestation by the thick-spored bogberry bare-bones are mainly pink leaf spots, which are followed by the appearance of the white mycelium on the plant surface. The species has been found in northern, central and southeastern Europe.

Macroscopic features
The thick-pored bogberry basidia is initially invisible to the naked eye, the initial symptoms are yellowish-colored pink spots on the leaves of the infected plant. The spots sometimes merge. The thin white mycelium of the fungus later emerges on the underside of the leaf between the leaf veins and from there overgrows the entire plant.
Microscopic features
The mycelium of the thick-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 clusters between the cells of the plant epidermis. The basidia are long, unseptate and narrow-clumped, the spores hyaline and thin-walled. The latter are 2–6 µm wide and have 1–3 septa when mature .
distribution
In Europe, the distribution area of the thick-spore bogberry-naked basid includes central, northern and, with Romania, also south-eastern Europe. The species is linked to the occurrence of the bog bilberry ( Vaccinium expansum ).
ecology
The only known host of Thick Spore Rauschbeer-Nacktbasidie is the bogberry. The fungus feeds on the nutrients present in the storage tissue of the plants; its infestation is limited to the leaves of the 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.
