Una Nueva especie de Flammulina P. Karsten, F. cephalariae (Agaricales) encontrada en España

Based on morphological and molecular studies, we propose Flammulina cephalariae as a new
species to the scientific community. It grows in limestone soil on Cephalaria leucantha debris and its distribution seems to be limited to Losa Valley, in the provinc e of Burgos (Northem Spain). We offer a description, its iconography and a comparison with similar taxa, and we include also a key for European species of genus Flammulina P . Karsten.
