Biodiversity Of The Foliose Lichens From Wudalianchi In China

In the paper,813specimens of foliose lichens in Wudalianchi had been preliminarilystudied by the ways of morphology, anatomy, chemistry and phytogeography.89species,23genus,10families and4orders had been reported. Among them2werenew to China: Phaeophyscia insignis (Mereschk.) Moberg and Heterodermia appalachensis(Kurok.) W. Culb.,47were new to Heilongjiang Province: One of the species belongs to thegenu Dermatocarpon.10belong to Peltigera. One belongs to Lobaria.8belongs toLeptogium. One belongs to Menegazzia. One belongs to Cetrelia. One belongs toFlavoparmelia.2belong to Flavopunctelia. One belongs to Melanelia.4belong toMyelochroa.4belong to Parmelia.3belong to Parmotrema.2belong to Punctelia. Onebelongs to Rimelia.4belong to Xanthoparmelia.5belong to Heterodermia.9belong toPhyscia.8belong to Physconia.16belong to Phaeophyscia. One belongs to Candelaria.2belong to Coccocarpia.4belong to Xanthoria.There are3types of the foliose lichens in Wudalianchi according to the difference ofvegetal substrate: epiphloeodal lichens (14genus,42species), saxicolous lichens (20genus,53species), terrestrial lichens (one genus,3species).The geography analysis showed that these species could be classified into six categories:11species belong to Cosmopolitan element(12%),37belong to North Temperateelement(41%),13belong to Eastern Asia-North America element(15%),13belong to EasternAsia element(15%),13belong to Pantropical element(15%) and2belong to Sino-Endemicelement.The dominant family of the foliose lichens in Wudalianchi are Physciaceae which have4genus,38species, Parmeliaceae which have11genus,24species and Peltigeraceae whichhave one genus,11species. The above three families totally have16genus,73species, partlytake up73%and82%of the genus and species of the foliose lichens in Wudalianchi. Twogenus which have more than10species are Phaeophyscia which have16species andPeltigera which have11species. The genus which have5to9species are Physcia whichhave9species, Physconia which have8species, Leptogium which have8species andHeterodermia which have5species. The above6genus totally have57species of the foliose lichens which take up64%of the total number of the species, at the same time,they only takeup27%of the total number of the genus. They are dominant genus.Classified descriptions of the foliose lichens in Wudalianchi had been made.
