Pucciniastrum areolatum is a species of rust fungus that infects Vaccinium spp., particularly bilberry and lingonberry. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found to be widely distributed, with a high frequency of infection on Vaccinium myrtillus and V. vitis-idaea. The fungus typically produces yellowish-orange uredinia and telia on the underside of leaves, causing damage to the host plants. It is considered a common and widespread species in the region's acidic soils and coniferous forests.

Cherry-spruce rust fungus (Pucciniastrum areolatum) on spruce cone scales in Tarkhovka Park, west from Saint Petersburg. Russia, May 10, 2021Unnamed Road, Sankt-Peterburg, Russia, 197701Observations of Pucciniastrum areolatum in Leningrad Oblast and north-western Russia reveal its presence on spruce cones. The fungus was found near Lisiy Nos, west of Saint Petersburg, on May 9, 2017, and in Tarkhovka Park, also west of Saint Petersburg, on May 10, 2021. In both locations, the fungus infected spruce cones, with visible signs of infection on cone scales. Close-up observations showed the fungus inside spruce cones and on cone scales. The repeated sightings in the same region over several years suggest that Pucciniastrum areolatum is established in the area and can infect spruce trees, potentially causing damage to the local ecosystem. The fungus was observed in May, indicating its activity during this time of year in north-western Russia.
