AI-generated description

Resupinatus applicatus is a species of fungus that grows on decaying wood. In St. Petersburg and Leningrad Oblast, it has been found on coniferous and deciduous trees, particularly on spruce, fir, and birch. It typically fruits in late summer to early autumn. In north-western Russia, it is considered a rare species, with scattered records from the regions of Murmansk, Arkhangelsk, and Vologda. The fungus has a resupinate to dimidiate cap, 0.5-2 cm wide, with a wavy or lobed margin, and a hairy to velvety surface that is greyish-brown to dark brown in color.

AI-generated summary of observations

Observations of the fungus Resupinatus applicatus in Leningrad Oblast and north-western Russia reveal small black oysterling mushrooms growing on logs. On May 6, 2019, near Lisiy Nos, west of Saint Petersburg, the mushrooms were found on a log, with a close-up view showing their detailed structure. The underside of the mushrooms was also observed, providing further insight into their morphology. The specimens were found to be small and black, characteristic of the Resupinatus applicatus species. These observations suggest that the fungus is present in the region, particularly in areas with suitable substrate such as logs. The specific location near Lisiy Nos and the time of year, May, may indicate a preferred habitat or growth period for the species in this region. Further study could confirm the identity and distribution of Resupinatus applicatus in north-western Russia.
