Penicillium chroogomphum is a species of fungus that belongs to the genus Penicillium. It has been found in St. Petersburg, Leningrad Oblast, and other parts of north-western Russia, typically growing on soil, plant debris, and organic matter. The fungus produces greenish-blue colonies with a velvety texture and produces penicillin-like structures. In the region, it has been isolated from various environments, including forests, fields, and urban areas, and is considered a common species in the local mycobiota.
The observation of Penicillium chroogomphum in Leningrad Oblast and north-western Russia revealed a unique association with the Copper spike mushroom (Chroogomphus rutilus). On August 16, 2017, near Toksovo, north of Saint Petersburg, a specimen of Chroogomphus rutilus was found to have its gills infected with Penicillium chroogomphum. This fungus was observed growing on the gills of the mushroom, indicating a possible symbiotic or parasitic relationship between the two organisms. The presence of Penicillium chroogomphum on the Copper spike mushroom suggests that this fungus may play a role in the ecology of the mushroom, potentially affecting its growth, reproduction, or decomposition. Further study is needed to fully understand the nature of this association and its implications for the ecosystem. This observation highlights the diversity of fungal interactions in the region and the need for continued exploration of these complex relationships.
