Saint Petersburg, Russia, May 27, 2017ulitsa Professora Popova, 2к1, Sankt-Peterburg, Russia, 197022Observations of Gyromitra sphaerospora in Leningrad Oblast and north-western Russia reveal distinct characteristics. The stem of the fungus is notably ribbed, as seen on display at the Botanic Gardens of Komarov Botanical Institute in Saint Petersburg, Russia, on May 27, 2017. Additionally, large masses of Gyromitra sphaerospora mushrooms were observed, also at the Botanic Gardens on the same date. These observations highlight the unique features and growth patterns of this fungus species in the region. The ribbed stem is a distinctive feature, while the formation of large masses suggests that Gyromitra sphaerospora can thrive in certain environments in Leningrad Oblast and north-western Russia. These characteristics are significant for identifying and understanding the behavior of this fungus in its natural habitat. Further study could provide more insights into its ecology and distribution.
