Russia, September 1, 2017Sosnovaya Ulitsa, 17, Rappolovo, Leningradskaya oblast', Russia, 188667Observations of Physarum album in Leningrad Oblast and north-western Russia revealed the species' presence on various substrates. On August 12, 2017, sporangia were found under bark on a spruce log in Kannelyarvi, 45 miles north of Saint Petersburg. Later, on August 21, 2017, drying sporangia were observed on a red conk mushroom in Sosnovka Park, Saint Petersburg. On September 1, 2017, the slime mold was found on a spruce log near Rappolovo and Toksovo, with multiple heads present. Another observation on the same day and location revealed the species' presence, indicating a possible abundance of Physarum album in the region during late summer. These findings suggest that Physarum album can thrive on different substrates, including tree bark and fungi, in the forests of north-western Russia. The species appears to be active during the late summer months.
