Extract from Wikipedia article: Leccinum holopus, commonly known as the white birch bolete, white bog bolete, or ghost bolete, is a species of bolete fungus in the family Boletaceae found in northern Asia, Europe, and northeastern North America. It associates with birch trees and is typically found in boggy or swampy areas, often growing among sphagnum moss.
Leccinum holopus is a species of bolete fungus that grows in association with birch trees. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically fruits in late summer to early autumn, often in moist, sandy soils under birch stands. The cap is 4-8 cm in diameter, white or pale brown, and covered with fine, downy hairs. The stem is white, 6-10 cm tall, and 1-2 cm thick. It has a distinctive white or pale yellow pore surface that bruises pinkish-brown when injured. Local records indicate it is a relatively common species in the region, particularly in areas with abundant birch vegetation.

Russia, September 1, 2018Saint Petersburg, Russia, 197755Observations of Leccinum holopus in Leningrad Oblast and north-western Russia show that the fungus grows in various habitats, including swamps, forests, and marshes. It is often found near white birch trees and can be associated with other mushroom species such as Cortinarius flexipes, Lactarius vietus, and Mycena megaspora. The fungus has been observed in different stages of development, from mature caps to old and damaged specimens. Some observations also noted the presence of gall-forming fungi damaging the stems of Leccinum holopus. The fungus appears to be widespread in the region, with sightings recorded in multiple locations, including Kanneliarvi, Duplianskoe Marsh, Kavgolovskoe Lake, Sosnovka Park, and Yuntolovsky Park, between August and October from 2007 to 2018.
