(Carex myosuroides)
Kobresia is a genus of plants in the sedge family. They are sometimes called bog sedges. These perennial sedges are quite similar to Carex species in appearance. The genus is widespread across much of Europe, Asia and North America, with many species native to the Himalayas. Carex myosuroides (syn. Kobresia myosuroides), the mouse-tail bog sedge, is a species of sedge (family Cyperaceae) with a circumboreal distribution. It is the only known sedge to have ectomycorrhizal associations. It is a known host to a number of fungi, including Anthracoidea elynae, Arthrinium puccinioides, Cladosporium herbarum, Clathrospora elynae, Lophodermium caricinum, Phaeosphaeria herpotrichoides, Schizonella melanogramma, Septoria punctoidea and possibly to Micropeziza cornea.
