A brief discussion of the Encyclopedia of Life and the LifeDesks websites as a means to assemble and publish species pages and taxonomic information on the internet, for both the scientific community and the public, is provided. The lichen family Parmeliaceae is the first large group of lichenized fungi for which a concerted effort is currently being undertaken to produce substantial content for the EOL.

The new species, Menegazzia jamesii Louwhoff & Kantvilas from Victoria and Tasmania, closely related to M. pertransita (Stirt.) R. Sant., is described. Chemical and nomenclatural notes on M. caliginosa P. James & D. J. Galloway and M. pertransita are provided, and the new combination, M. stirtonii (Zahlbr.) Kantvilas & Louwhoff, is proposed. The name M. weindorferi (Zahlbr.) R. Sant., widely applied in Australian literature, is considered synonymous with M. pertransita, whereas M. bullata (Stirt.) Bitter is considered a synonym of M. stirtonii.

Studies of type specimens and other specimens of Menegazzia subsimilis and M. dissecta have shown that they are referable to the same taxon. Thus, M. dissecta is reduced to synonymy with M. subsimilis, which is characterized by lacerate soralia protruding from lobe apices or vertical lobules (protuberances), small perforations and the presence of the stictic acid complex in the medulla. It has 2-spored asci. The synonymy implies that M. subsimilis has a much wider distribution range than previously known. It is reported here from Oceania (Hawaii, Solomon Islands), Asia (Japan, Papua New Guinea, Russia), Europe (Austria, Germany, Portugal), South America (Ecuador, Peru), the Caribbean (Dominican Republic, Jamaica) and North America (Canada, USA).

Menegazzia neotropica sp. nov. is described from upper montane forest remnants and paramos in Ecuador, Colombia and Venezuela. It is characterized by short-pedicellate apothecia with ridged margins that partly obscure the discs, and by narrow, glossy lobes with brown-black margins. Menegazzia dissecta is recorded from South America for the first time and M. terebrata is recorded from Colombia and Ecuador for the first time.
