Synonym: Reticularia dudkae.
Extract from Wikipedia article: Tubifera dudkae is a species of slime mold in the class Myxogastria. Unlike its relatives, T. dudkae does not form pseudoaethelia with distinct sporangia, or at least the sporangia are not visibly distinct or rod-shaped like other members of Tubifera. They are found growing on damp, dead wood in temperate forests, including where it was first documented in Ukraine. T. dudkae is found in mixed and coniferous forests across Europe and Asia
Tubifera dudkae is a species of slime mold characterized by its unique spore-bearing structures and growth habits. In St. Petersburg, Leningrad Oblast, and north-western Russia, it has been found in moist, temperate forests, often on decaying wood or plant debris. The species typically fruits in late summer to early autumn, forming iridescent, pinkish-gray sporangia that are 1-3 mm in diameter. Its distribution in the region is relatively rare, but it can be locally abundant in suitable habitats, such as coniferous and mixed forests with rich undergrowth and moderate humidity.
Slime mold Tubifera dudkae on a log when exposed to regular daylight as well as when illuminated by a 365 nm ultraviolet (UV-A) blacklight near Lisiy Nos, west from Saint Petersburg. Russia, July 19, 2024
Russia, Saint Petersburg, Лисий Нос, 197755, 1-Я Полянская Улица 19The observation of Tubifera dudkae in Leningrad Oblast and north-western Russia revealed notable characteristics under different lighting conditions. On a log near Lisiy Nos, the slime mold was visible when exposed to regular daylight, suggesting its ability to thrive in natural light environments. When illuminated by a 365 nm ultraviolet (UV-A) blacklight, the species also remained visible, indicating its potential to reflect or absorb UV-A radiation. This observation suggests that Tubifera dudkae may have adaptations to survive and grow under various light conditions, including those with UV-A components. The ability to thrive in both daylight and UV-A illuminated environments could contribute to its distribution and abundance in the region. Further study is needed to understand the implications of these observations on the species' ecology and behavior. The location near Lisiy Nos, west of Saint Petersburg, provided a unique setting for this observation.
