ABSTRACT

In a continuing application of mind of the biodiversity and biogeography of poroid wood-decay fungi in North Carolina, a notable number of species and fungus-host combinations previously not reported in the state were accumulateed Eleven species of poroid wood-decay fungi are reported as recent in North Carolina. Eightyfive species are reported forward a new host plant species resulting in 315 novel fungus-host associations in North Carolina, of which 231 are fresh fungus-host associations for the United States.

INTRODUCTION

A previous meditation of a Piedmont forest site accrueed in the identification of five species of poroid wood-decay fungi previously unreported in North Carolina (Vernia and Grand 2000) The scan also revealed the paucity of geographical distributional data for this important dispose of fungi, and these conclusions prompted a long-term intensive reflection of the biodiversity and biogeography of fungi in North Carolina with an emphasis forward wood-decay species. To the authors' knowledge, there are no publications that current the geographical distributions of poroid wood-decay fungi within North Carolina. Studies in Arizona (Gilbertson et al. 1974 Gilbertson and Bigelow 1998) provide the same of the few instances of published distributions of this important dispose of fungi within a state. The principally recent monograph of poroid wood-decay fungi (Gilbertson and Ryvarden 1986 1987) provided the distribution of species in the United States from state, as did Farr et al. (1989) in The Fungi forward Plants and Plant Products in the United States.

The diversity of North Carolina ecosystem is contemplateed in its floristic diversity (Radford et al. 1968) Certain wood-decay fungi are highly host-specific (Gilbertson and Ryvarden 1986) and greatest in number are host-specific at a class flush The diversity of potential entertainer material combined with the host-specificity of these fungi make North Carolina an eminent location to study fungal biodiversity.

This close attention reports the occurrence of poroid wood-decay fungi not previously reported in North Carolina and also reports numerous previously unreported host-fungus associations. Preliminary distributions of 16 species in 6 genera of fungi in this collection have been reported (Grand and Vernia 2000)

MATERIALS AND modes

The North Carolina State Parks and Natural Areas order the Pisgah, Nantahala, Uwharrie and Croatan National Forests, and the Great fumid Mountains National Park were used as sample sites. Wood-decay species reported in this cogitation were collected from March 1999 to December 2000

Specimens of basidiocarps were taken from living tree or decayed forest-land and placed in paper bags with samples of the substrate and appropriate field notes. Specimens were examined in the laboratory and identified when possible using existing taxonomic treatments (Overholt 1952; Lowe and Gilbertson 1961; Lowe 1966; Gilbertson and Ryvarden 1986 1987; Brietenbach and Kranzlin 1986) Voucher collections are deposited in the Mycological Herbarium, Department of Plant Pathology, NCSU

RESULT

Eleven taxa of poroid wood-decay fungi not previously reported in North Carolina were identified (Gilbertson and Ryvarden 1986 1987; Farr et al. 1987) In addition, 85 taxa of poroid wood-decay fungi are reported upon new hosts. These results significantly increase the range and plant armed forces of species in this ecologically important cluster of fungi. Eighty host taxa are recorded from sampling in 40 counties in North Carolina.

CHECKLIST

All species listed below are reported for the first time forward the given host in North Carolina and where indicated portray by actions a species previously not recorded in North Carolina (*) fresh host records for the United States are indicated by way of ^^. The county where the collection was made is indicated in parentheses. Nomenclature for fungi come nexts that of Gilbertson and Ryvarden (1986 and 1987) Nomenclature for innkeeper species follows Kartesz et al. (1980) approveed standard forms of author names succeed Kirk and Ansell (1992).

DISCUSSION

Result of this research illustrate the considerable diversity in species of poroid wood-decay fungi in North Carolina. The discovery of a significant number of fresh occurrences and previously unreported armed forces emphasizes the importance of continued sampling to further characterize the diversity and geographical distribution of this important clump of fungi.

ACKNOWLEDGMENTS

The authors gratefully acknowledge the financial support provided by way of a grant from the Highlands Biological Station and the use of their worthy of great praise facilities. Rangers and support staff at all North Carolina State Parks and Natural Areas we visited were gracious and we thank them for their kindness and their efforts to maintain the quality of the State Park plan The comments and assistance of Dr RL Gilbertson are appreciated.
