Extract from Wikipedia article: Sphaerosporella brunnea is a pryophilic species of small ascomycete cup fungi that commonly makes its habitat on burned substrates. Sphaerosporella brunnea is synonymous with Sphaerosporella hinnulea, Trichophaea brunnea, Peziza brunnea and numerous other fungi due to previously conceived variations in the fungi's habitat, substrate, and color ranging from dark brown to a light yellow-orange, however these differences were soon found to be negligible. S. brunnea is ectomycorrhizal, suspected to be saprobic, and is thought to be commonly widely distributed in Australia, Asia, the eastern United States and parts of Europe, such as Germany, Austria, Poland, the United Kingdom, and Sweden. This minuscule fungi is a detrimental contaminant in black truffle orchards, where Sphaerosporella brunnea seems to compete and inhibit the infection and growth of Tuber fungi, causing economic loss due to decreased infection rates of Tuber species.
Sphaerosporella brunnea is a species of fungus that belongs to the family Pyronemataceae. It is characterized by its small, brown to dark brown apothecia and ellipsoidal to cylindrical spores. In St. Petersburg, Leningrad Oblast, and north-western Russia, Sphaerosporella brunnea has been found growing on soil, mosses, and plant debris in coniferous and mixed forests, often associated with spruce and pine trees. The fungus typically fruits in late summer to early autumn, producing scattered to gregarious apothecia that are 0.5-2 mm in diameter.

Brown discs with tiny hairs of cup fungus Sphaerosporella brunnea growing on charcoal on a bonfire site in a coastal forest between Lisiy Nos and Olgino, west from Saint Petersburg. Russia, September 6, 2018Primorskoye Shosse, 4а, Lakhta, Sankt-Peterburg, Russia, 197229Observations of the fungus Sphaerosporella brunnea were made in Leningrad Oblast and north-western Russia. The fungus was found growing in dense clusters or colonies on sites of old campfires and bonfires, particularly among charcoal and burnt soil. Brown discs with tiny hairs were characteristic of the fungus. Locations included areas 35 miles north of Saint Petersburg, such as Lembolovo - Orekhovo, and coastal forests between Lisiy Nos and Olgino, west of Saint Petersburg. The fungus was observed on multiple dates, including August 8, 2017, and September 6, 2018. In all cases, the fungus thrived in areas with charred remains, suggesting a preference for burned environments. The consistent presence of Sphaerosporella brunnea in these areas indicates its ability to colonize and grow in disturbed, fire-affected habitats.
