The genusCatapyreniums. lat. (Verrucariaceae) in the Iberian Peninsula and the Balearic Islands

Abstract

AbstractA taxonomic treatment of the genera included inCatapyreniums. lat. in the Iberian Peninsula and the Balearic Islands is provided, based on study ofc. 2000 specimens from both herbaria and fresh material collected by the authors from 2005 to 2009 in numerous localities.A total of 33 species belonging to six of the eight genera included inCatapyreniums. lat. are present in the region, which correspond toc. 80% of species from Europe. The genera areAnthracocarponBreuss,CatapyreniumFlot. (Catapyreniums. str.),HeteroplacidiumBreuss,InvolucropyreniumBreuss,NeocatapyreniumH. Harada andPlacidiumA. Massal. The genusNeocatapyreniumis reported for the first time from this region.Clavascidium liratum, the only representative of the genusClavascidiumin the region, has been reduced to synonymy withAnthracocarpon virescens.Heteroplacidium acervatum, H. congestumandNeocatapyrenium cladonioideumare new to Europe.Involucropyrenium pusillum, only previously known from Austria,I. waltheri, an arctic-alpine species, andNeocatapyrenium latzelii, known from Croatia and Greece, are cited for the first time in the Iberian Peninsula.Placidium subrufescensandP. tenellum,two mainly Mediterranean species, are also new records from the Iberian Peninsula.Placidium boccanumis here for the first time cited in Spain, andAnthracocarpon virescens,Heteroplacidium contumescens,Placidium imbecillumandP. micheliiare new to Portugal. Most of the remaining species showed a considerable expansion of their known ranges.Placidium pyrenaicumis reduced to synonymy withP. velebiticum.Keys to genera and species occurring in the Iberian Peninsula and the Balearic Islands are presented.
