A checklist of xylophilous basidiomycetes (Basidiomycota) in mangroves

Based on intensive search of literature records of xylophilous basidiomycetes in mangroves, a list with 112 species is presented. These species are distributed in 63 genera, 27 families and 9 orders. Polyporaceae is the most represented family with 33 species; Phellinus is the genus with the highest number of species (7). Brazilian mangroves, with 55 species, are the best known areas. The most frequent host is Rhizophora mangle with 34 species recorded on it. For each species the localities and substrates are provided, when these data were available in the respective original article.

Santa Catarina Island mangroves 3: a new species of Fuscoporia

Fuscoporia bifurcata is described from southern Brazil based on collections from mangrove areas on Santa Catarina Island, in the state of Santa Catarina. The new species is characterized by hymenial setae with a bifurcate or spiny apex. A description with illustrations, an updated key to species of Fuscoporia from southern Brazil and a key to species of Hymenochaetaceae reported from mangroves are provided.

Santa Catarina Island mangroves 4 - xylophilous basidiomycetes

Itacorubi, Ratones, Rio Tavares and Saco Grande are natural mangrove forests in the western part of Santa Catarina Island, in southern Brazil. Thirty-three basidiomycetes were identified during a survey of xylophilous basidiomycetes in these mangrove forests from May 2005 to August 2006. The species are distributed among 9 families and 24 genera. Fifteen species are new records from mangrove forests of the world and eight species are recorded for the first time from the State of Santa Catarina.

Addition to the knowledge of Xylaria (Xylariaceae, Ascomycota) in Santa Catarina, Southern Brazil

⎯ Xylaria specimens have been collected in the State of Santa Catarina, Southern Brazil, since the 19th century, primarily by European naturalists such as Ernst Ule and Alfred Möller. Few comprehensive surveys or Xylaria collections have been made by Brazilians in the State until recently. New knowledge has been gained from the authors’ recent survey and examination of specimens from the Florianópolis metropolitan area. Among the species discussed are a new species, Xylaria nigromedullosa, and eleven other species, including X. adscendens, X. allantoidea, X. anisopleura, X. comosa, X. cubensis, X. curta, X. ianthinovelutina, X. magnoliae var. microspora, X. mellissii, X. obovata, and X. telfairii. Most collections were obtained from dead wood, with a few found growing on fallen fruits. Seven species are new records from Santa Catarina and X. magnoliae is a new record for Brazil. Full descriptions, illustrations, and a key to the Xylaria collections now curated in FLOR are provided.

Multigene phylogeny of the Phallales (Phallomycetidae, Agaricomycetes) focusing on some previously unrepresented genera

Phylogenetic relationships within the Phallales were estimated via combined sequences: nuclear ribosomal large subunit (LSU), second largest subunit of RNA polymerase (rpb2), and mitochondrial ATPase subunit 6 (atp6). The ingroup is represented by 62 taxa comprising 18 genera and 44 species, including members of the Clathraceae, Claustulaceae, Gastrosporiaceae, Lysuraceae, Phallaceae and Protophallaceae. Sixty-one new sequences were generated, including tropical and subtropical taxa. This is one of the first studies discussing the phylogenetic placement of Abrachium, Aseroë, Blumenavia, Gastrosporium, Jansia and Xylophallus. Gastrosporiaceae was demonstrated to be sister to Phallaceae and an emended description of the order is presented. Aseroë was demonstrated to be polyphyletic and as a result, A. arachnoidea is transferred to Lysurus.

Sequestrate fungi from Patagonian Nothofagus forests: Cystangium (Russulaceae, Basidiomycota).

Six species of Cystangium, a genus of sequestrate taxa related to Russula, were collected in Patagonia (Argentina and Chile) during autumn 2001. Two species, C. depauperatum Singer & A.H. Sm. and C. nothofagi (E. Horak) Trappe, Castellano & T. Lebel, were already known from this region, while four new species, C. domingueziae, C. gamundiae, C. grandihyphatum and C. longisterigmatum, are described, illustrated and a key to the species is provided. In addition, sequences of the ITS (rDNA) region were obtained to explore the phylogenetic relationships of our South American Cystangium species.

Costa Rican gasteromycetes (Basidiomycota, Fungi): Calostomataceae, Phallaceae and Protophallaceae

Costa Rican specimens of Calostomataceae, Phallaceae and Protophallaceae (gasteroid basidiomycetes) kept at Herbarium F were examined and identified. Eleven species belonging to seven genera were recognized: Calostoma cinnabarinum, C. lutescens (Calostomataceae), Aseroë rubra, Clathrus columnatus, Laternea pusilla, L. triscapa, Ligiella rodrigueziana, Phallus indusiatus, P. duplicatus (Phallaceae), Protubera maracuja and P. jamaicensis (Protophallaceae). Calostoma lutescens is described with larger spores than those reported for the species, but molecular data confirmed the species identification. The occurrence of Protubera species in Costa Rica is reported for the first time.

Santa Catarina Island mangroves 5: Corticioid fungi and an updated checklist of xylophilous fungi and pseudofungi1

Abstract The corticioid fungi from Santa Catarina Island mangroves were surveyed, and 42 specimens corresponding to 15 species and 13 genera were identified. The most commonly found species was Hjortstamia crassa, and the Itacorubi mangrove was the area where more specimens were found (17 out of 42 specimens). Most of the specimens were collected on dead wood, and the most common host was Avicennia schaueriana. Six species were previously unknown from mangroves around the world; Phanerochaete subglobosa is recorded for the first time outside Asia, Hjortstamia amethystea is newly reported from Southern Brazil, and four species are new records from the State of Santa Catarina. Taxonomic remarks are given for the treated species, and an updated checklist of xylophilous fungi and pseudofungi (Myxomycetes) known from Santa Catarina Island mangroves is provided.
