Vizzini A., Contu M. & Musumeci E. (2010) A new species of Hypholoma from coastal grasslands of Gallura (Sardinia, Italy). – Sydowia 62 (2): 317–323.

Hypholoma litorale is described as a new species on the basis of collections made near Olbia (Sardinia, Italy), in coastal grasslands. It seems to be close to the north-American species H. olivaceotinctum, but it differs in several respects both macro- and micromorphologically. Photographs of fresh material and of the main micromorphological features of the new species are provided.
Keywords: Agaricomycetes, Strophariaceae, Hypholoma litorale sp. nov., taxonomy.
