New records of lignocellulolytic basidiomycetes ( Fungi ) : Parque

In a recent survey on lignolicolous basidiomycetes in the State Park of Serra do Tabuleiro (Santa Catarina, Brazil), 27 previously unrecorded species of polypores were collected, namely Antrodia albida, Ceriporiopsis pannocincta, Coriolopsis rigida, Fomitiporia fl avomarginata, F. punctata, F. undulata, Fuscoporia callimorpha, F. ferrea, F. punctatiformis, Hexagonia hydnoides, Junghuhnia undigera, Megasporoporia cavernulosa, M. setulosa, Pachykytospora papyracea, Perenniporia medulla-panis, P. ohiensis, P. stipitata, Phellinus allardii, P. bambusarum, P. cesatii, P. melanodermus, Phylloporia chrysita, Polyporus leprieurii, Rigidoporus lineatus, Schizopora fl avipora, S. paradoxa and Trametes socotrana.


Introduction
The white-and brown-rot caused by basidiomycetes, which is a highly variable process, mainly depends upon decomposer organisms and plant species, and also on the micro-habitat (Blanchette, 1995).The high level of biological diversity is very important in tropical forests (Gaston, 2000;Gilbert et al., 2002;Suryanarayanan et al., 2003).Even though these habitats cover only 7% of the Earth's surface, they represent more than 50% of species from a biota whose destruction has been accelerated in recent years.Deforestation is therefore achieving the extinction of hundreds of thousands of plant species and all associated species, as well as lignocellulolytic basidiomycetes (Myers, 1997;Wilson, 1997;Sippola et al., 2001).
The park has a wide diversity of relief and habitats, which permits the protection of an unestimatable biological diversity that has become one of the most representative remnants of the Atlantic Rain Forest of Southern Brazil (Zambonim, 2001).
A former lignolitic basidiomycetes inventory carried out at P.E.S.T. registered the presence of 47 species, 14 of which were the fi rst records from Santa Catarina State (Groposo and Loguercio-Leite, 2004).
This study was proposed in order to expand knowledge about the diversity of wood rot basidiomycetes (Basidiomycota) at P.E.S.T.
In conclusion, this survey added 27 species of lignocellulolytic basidiomycetes (Basidiomycota) to a previous inventory, with 47 species (Groposo and Loguercio-Leite, 2004).Therefore, the number of species recorded to date from the P.E.S.T. totals 74.
All of them are wood white-rots, except Antrodia albida, which is a brown rot.
