ABSTRACT

Collections of macromycetes made in seven municipalities in southern Brazil, viz. six in Rio Grande do Sul and one in Santa Catarina, are listed. They belonged to the Myxomycota (6 spp.), Ascomycota (54 spp.) and Basidiomycota (189 spp.). First records for Brazil could be Battarrea phalloides, Amanita rubescens, Boletus edulis and Mycena filopes, the last three found under exotic Pinus.

Key words: Macromycetes, Rio Grande do Sul, Santa Catarina, Brazil

RESUMO

São listadas as coletas executadas pelo autor em sete municípios no sul do Brasil, sendo seis no estado de Rio Grande do Sul e um no estado de Santa Catarina. Pertencem à Myxomycota (6 espécies), Ascomycota (54 espécies) e Basidiomycota (189 espécies). Primeiros registros para o Brasil são aparentemente: Battarrea phalloides, Amanita rubescens, Boletus edulis e Mycena filopes, as últimas três encontradas sob espécies de Pinus.

INTRODUCTION

The author has made mycological collections in southern Brazil since 1990. Collecting was done as a pastime, at random, without a definite plan. Collecting localities are given in Table 1. The majority of collections come from the author's rural property, in Nova Petrópolis, at 565 m a.s.l. Most localities are in north-eastern Rio Grande do Sul, but Rolante is in eastern Rio Grande do Sul, and Piçarras is in the state of Santa Catarina.

MATERIALS AND METHODS

Collections were photographed and macroscopically described (in German, with colour notations following Küppers' 1978 codes) from materials still fresh and alive. Exsiccates of most collections were sent to the mycologist André A. R. de Meijer, who studied and determined only those that he considered of sufficient size and sufficiently well annotated (Table 2). Other specialists identified a few collections as indicated. Table 2 also includes a few collections received by the author from other persons, also determined by de Meijer. Exsiccates, descriptions and photo negatives of the collections listed are preserved in MBM (Museu Botânico Municipal, Curitiba, State of Paraná, Brazil). For photography a camera Yashica Fx-3 super 2000 was used, with lens Sigma 28.1-90 for macrophotography without usage of flash.

Questions about the identifications should be directed to André de Meijer (Sociedade de Pesquisa em Vida Selvagem e Educação Ambiental), Caixa Postal 305, 80.001-970 Curitiba, Brazil.

RESULTS AND DISCUSSION

Table 2 shows the names of species identified with relative certainty. Species only identified to genus level are not included, unless they represent taxa little known or possibly new for southern Brazil (compare Putzke 1994 for Agaricales).

The majority of collections listed in Table 2 are from secondary native forest. Most of the others are from pure or mixed stands of exotic Acacia decurrens, Pinus spp. and Eucalyptus spp., or are from the author's home garden of ornamental exotic and food plants. Table 3 shows how the collections of Table 2 are distributed over substrate and organism types.

ACKNOWLEDGEMENTS

André de Meijer sent duplicates of some collections of ascomycetes to specialists abroad for determination. John H. Haines (1996), Donald H. Pfister (1997) and André Aptroot (1998) were so kind as to identify the collections. The author is very grateful to all these persons, and also to Maria Eduarda Amazonas Lopes, Kaneyoshi Ueno e Ronaldo Fleck, allowing him the inclusion in Table 2 of one, two and four respectively of their collections. He also thanks Else C. Vellinga for providing useful comments on the manuscript.
