IntroduçãoCladonia P. Browne é o maior dos 12 gêneros reconhecidos por Stenroos et al. (2002a) para a família Cladoniaceae, e possui atualmente mais de 400 espécies (Stenroos et al. 2002a) conhecidas em todo o mundo. De acordo com Stenroos et al. (2002b), o gênero pode ser dividido em quatro Supergrupos: Cladonia, Perviae, Cocciferae e Crustaceae.Segundo os estudos filogenéticos realizados por Stenroos et al. (2002b) The main goal of the present work was to make an intensive survey of Cladonia species that grow in restinga and on the rocky shores of this region. Nine species belonging to Supergroups Cocciferae, Crustaceae and Perviae were found, and two of them were new records: Cladonia squamosa for Paraná and C. palmicola for Santa Catarina. All of the species recorded occur in restinga and seven of them are also found along rocky shores. An identification key, descriptions, comments and illustrations are provided.

Four species of the genus Graphis Adans. are described as new to science, namely G. archeri, G. invisibilis, G. lueckingii and G. paranaensis. These new species were found growing in restinga forest in southern Brazil.

O levantamento das espécies de liquens parmelioides eciliados que ocorrem em costões rochosos dos estados do Paraná e de Santa Catarina revelou a presença de doze espécies pertencentes aos gêneros Canoparmelia (1), Hypotrachyna (2), Parmotrema (4), Pseudoparmelia (1) e Xanthoparmelia (4). Entre as novas ocorrências estão Parmotrema mordenii e Xanthoparmelia subramigera para o Paraná e para Santa Catarina, Pseudoparmelia cubensis e Xanthoparmelia catarinae para o Paraná, enquanto que Hypotrachyna osseoalba, Parmotrema dactylosum e P. endosulphureum são para Santa Catarina. São apresentadas chave de identificação, descrições, comentários e ilustrações.

Three new corticolous Diorygma species are described from Brazil. Diorygma incantatum has transversely 29–31-septate, filiform ascospores 105–108×6 µm, and produces an unidentified substance with Rf 44 in solvent C. Diorygma pauciseptatum produces norstictic and connorstictic acids and has transversely 7–9-septate, I+ blue-violet, large ascospores 28–32×7 µm, surrounded by a gelatinous sheath c. 2 µm wide that is often somewhat expanded at one end. Diorygma tocantinense contains protocetraric acid and has muriform, broadly fusiform ascospores with rounded ends, 24–40×10–15 µm, surrounded by an gelatinous sheath up to c. 5 µm wide that is somewhat expanded at central parts of the ascospore. A revised world key is given to all currently known species of Diorygma.
