【摘要】 本文主要是对内蒙古赤峰地区大型真菌的物种多样性和区系多样性进行了调查研究。物种多样性研究结果表明,共采集大型真菌标本400余份,经鉴定为163种,隶属于72属40科12目2纲。包括担子菌门1纲10目37科68属158种,子囊菌门1纲2目3科4属5种,其中内蒙古新记录种32个,待定种1个。并按照《Ainsworth & Bisby′s Dictionary of The Fungi》第九版(2001)系统对物种名录进行编目。所有鉴定标本都保藏在吉林农业大学菌物所标本馆(HMJAU)。区系多样性研究结果表明,内蒙古赤峰地区的大型真菌区系成分十分丰富,具有10个种以上的科有4个,含65种,占赤峰地区大型真菌总数的39.8%,科的数目占总科数的5.6%。含有5个种以上的属有8个属,共计55种,占总种数的33.7%,而属的数目占总属的11.1%。此8个属中世界广布属有5个,其余3属为北温带分布属。从种的组成上看,世界广布种63个,占总种数的38.6%;北温带分布种有78个,占总种数的47.8%;除此之外还有东亚-北美间断分布种5个,占总数的3.1%;中国-日本分布种有5个,占总数的3.1%;欧亚大陆分布种4个,占总数的2.5%;北温带-澳大利亚分布种5个,占总数的3.1%;热东亚(热带、亚热带)及热带南美间断分布种2个,占总种数的1.2%。新记录待定种1种,占总种数的0.6%。说明赤峰地区大型真菌区系表现出明显的北温带区系特征。亲缘关系与大青沟区系更为接近。更多还原

【Abstract】 Species diversity, flora diversity in Chifeng region, Inner Monggolia Research were studied systematically in this paper.More than 400 specimens were collected, and 163 species were identified. According to morphological classification, these 163 species belong to 72 genus, 40 families, 12 orders and 2 classes. Among them 158 species from 1 classes, 10 orders, 37 families, 68 genera belong to Basidiomycota; 5 species from 1 classes, 2 orders, 3 families 4 genera belong to Ascomycota. T There are 1 unknow species of Lentinellus, and 32 new species to Inner Monggolia. The diversity catalogue of these 163 species was arranged according to Dictionary of Fungi (2001, 9th), and the voucher specimens were deposited in the Herbarium of the Mycological Institute, Jilin Agricultural University (HMJAU).The result of the flora diversity study indicated that the fungi flora is very rich in the Chifeng region, Inner Monggolia. 4 families which contain more than 10 species contain 65 species, occupied 39.8% total number of Macorfungi in the Chifeng region and occupied 5.6% total family number. 8 genus which contain more than 5 species, 55 species in all, and occuped 33.7% total species number, 11.1% in the total genus number. In this 8 genus, contain 5 cosmopolitan, other 3 genus are North-temperature zone disperation. Regarding the species composition: 63 comopolitans occupied 38.6% total species number, 78 North-temperate zone species, occupied 47.8% total species number. And 5 Eastern Asia-North America species, occupied 3.1% in the total number. 5 China-Japan in common species, occupied 3.1%. 4 Eur-asian species, occupied 2.5%. 5 North temperate-Australia species, occupied 3.1%. 2 Eastern-tropical (tropical, subtropical) and tropical South America species, occupied 1.2%. and 1 new recorded undetermined specie, occupied 0.6%. All this suggests that Chifeng region display obvious temperate characteristics. The Fungi flora is very similar to that of the Daqingou.更多还原
