The lichen family Cladoniaceae in Paraiba, Pernambuco and Sergipe, Northeast Brazil
Field and herbarium studies of the lichen family Cladoniaceae in the states of ParaĂba, Pernambuco and Sergipe, Northeast Brazil, yielded 22 species, many of them being new reports for the region. The phenolic compounds identified in each species are reported. Cladonia clathrata Ahti & Xavier Filho, Cladonia polita Ahti, Cladonia polyscypha Ahti & Xavier Filho, and Cladonia rugicaulis Ahti are described as new. C. clathrata, C. rhodoleuca Vainio, C. rugicaulis, C. salzmannii Nyl., and C. subminiata Stenroos appear to represent an element confined to northeastern Brazil
Nuevos datos sobre nomenclatura, taxonomĂa y distribuciĂłn de algunas especies del gĂ©nero "Cladonia"
The name Cladonia diversa Asperges ex S. Stenroos is validated, and the species is reported as new to Japan. Cladonia angustiloba, earlier known from Macaronesia, is reported to extend to Faeroe Is., Denmark. Cladonia aspera Ahti & Kashiw. is an illegitimate later homonym of C. aspera (Flörke) Doign. The former name is still regarded as a synonym of C. sarmentosa, while the latter name is a synonym of C. gracilis subsp. gracilis. The type of C. dilleniana is stated to be from Bahama Islands rather than Turks and Caicos Islands. The volcano lichen C. vulcani is recorded from Iceland as new to Europe. The author citation of C. bacilliformis (Nyl.) Sarnth. and type location citation of C. glauca Flörke are corrected.Se valida el nombre Cladonia diversa Asperges ex S. Stenroos y se reporta nueva para JapĂłn. Cladonia angustiloba, anteriormente conocida de la Macaronesia extiende su área de distribuciĂłn hasta las islas Feroe, Dinamarca. Cladonia aspera Ahti & Kashiw. es el Ăşltimo homĂłnimo ilegitimo de C. aspera (Flörke) Doign. El primer nombre válido es considerado un sinĂłnimo de C. sarmentosa, mientras que este Ăşltimo es un sinĂłnimo de C. gracilis subsp. gracilis. El tipo de C. dilleniana procede de las islas Bahamas en lugar de las islas Turcos y Caicos. El liquen de los volcanes C. vulcani se cita de Islandia y constituye nueva cita para Europa. Se corrige la autorĂa de C. bacilliformis (Nyl.) Sarnth. y la indicaciĂłn locotĂpica de C. glauca Flörke
Additions to the vascular flora of the Berezovye Islands (Koiviston saaret), Karelian Isthmus, Russia
Ashort history of the floristic studies in the Berezovye Islands [Koiviston saaret] Nature
Reserve in the Gulf of Finland, Leningrad Region, Russia, is given. Based on the archival
field notes by Viljo Erkamo in 1934, recently discovered in Finland, and new findings by
the present authors during an excursion in 2008 42 vascular plant species, subspecies and
hybrids are reported as novelties for the Reserve. Further, 37 taxa are new to one ormore
of the four largest islands, Bol’shoy Berezovyy Island (Koivusaari), Zapadnyy Berezovyy
Island (Tiurinsaari), Severnyy Berezovyy Island (Piisaari) andMalyy Berezovyy Island
(Vasikkasaari). Further, some taxa, which are lacking in the recent checklist of the archipelago,
are listed on the basis of literature.Most of Erkamo’s finds areweeds and other
species benefited by man’s impact, apparently having totally disappeared due to the
strong decrease of the human population on the islands after the SecondWorldWar. Even
the recent novelties aremostly weeds and escaped ornamentals, but they also include several
indigenous taxa. Comments on the variation and spreading of some taxa are given.Ashort history of the floristic studies in the Berezovye Islands [Koiviston saaret] Nature Reserve in the Gulf of Finland, Leningrad Region, Russia, is given. Based on the archival

Taxonomic notes on Pycnothelia Dufour and Gymnoderma Nyl. (Cladoniaceae) in Madagascan Region
This study was focused on two species of lichen-forming fungi from Madagascan Region whose taxonomy has been controversial over the years, Cladonia mascarena Nyl. and Heterodea madagascarea Nyl. While some authors considered C. mascarena to belong to Cladonia, others place it in Pycnothelia Dufour. In this study three loci (ITS rDNA, rpb2 and ef1 alpha) were used to determine the phylogenetic placement of C. mascarena. Our results show that it belongs to Pycnothelia and the combination Py cnothelia mascarena (Nyl.) Nyl. is substantiated. In addition, a key to the genus Pycnothelia is provided. The morphological study of new specimens of Gymnoderma coccocarpurn Nyl. and H. madagascarea concluded that these taxa belong to a same species, confirming the extension of Gymnoderma Nyl. to Africa. The overlooked genus Baeoderma Vain. is regarded as a synonym of Gymnoderma, and its type species Baeoderma madagascareum (Nyl.) Vain. is referred to G. coccocarpum.Peer reviewe
