Sphaerosporella brunnea

Sphaerosporella brunnea is a pyrophilic 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....read more on Wikipedia.
