AI-generated summary of observations

Observations of Ditiola peziziformis in Leningrad Oblast and north-western Russia reveal the fungus grows on various tree species. In Sosnovka Park, Saint Petersburg, it was found on a small pine trunk in a swampy area in February and on a pine tree in March, appearing as small bright yellow mushrooms. In Petiayarvi, north of Saint Petersburg, the fungus was observed on spruce logs in September, manifesting as jelly-like growths and typical mushrooms. The observations suggest Ditiola peziziformis can thrive on different coniferous trees, including pine and spruce, in various environments, from swampy areas to forested regions, and can be present throughout the year, with sightings recorded in February, March, and September. These findings contribute to understanding the habitat preferences and seasonal occurrence of this fungus in north-western Russia.
