The collection specimens including macro-fungi and mycetes parasitize on macro-fungi were conducted the morphological studied.Explore the relationships of parasitism,descriptions, illustrations and line drawings of all species were provided in detail,as follows:fruiting body, subiculum morphology,color change,texture,and the structure of sporulation,shape and size of spore,the structure of asexual sporulation,spores,connections of host.Discussed the characteristics of adjacent and similar species,the relationships of parasite and new host. Structures of all species were observation with light Microscope,chlamydospores and basidiospores of some species were studied and photoed with Scanning-electron Microscope. Lists of seventeen parasites were given,the key of seventeen parasites was compiled.Hope to provide initial data for deep-level investigation and using.The research specimens in this paper from far east of Russia and Northeast of China.A total of specimens were collected from varied habitats in different latitudes and altitudinal zones. From these specimens 4 classis,8 orders,10 families,14 genera consisting of 17 species belonging to the Zygomycota,Fungi Imperfecti,Ascomycota and Basidiomycota were isolated and identified.Among them,there are two new species(Aschersonia flabelliformis,Lycoperdon applanatum),Marasmiellus ramealis on Boletinus pictus was new relationship of parasitism, four new records to China(Hypomyces luteovirens,Cordyceps jezoensis,Asterophora parasitica, Collybia cirrhata).Four species were have new host,there are Spinellus fusiger(7 new host:Collybia butyracea,C.dryophila,C.erythropus,C.alkalivirens,Mycena epipterygia,M.leptocephala,M.galericulata),Mucor mucedo(one new host:Lactarius piperatus),Cephalosporium candidum(one new host:Russula sp.),Sphaerotheca fuliginea(one new host:Boletus sp.).From the numbers of collection,the species Spinellus fusiger was most prevalent,with a relative occurrence frequency of(36%),secondly is Hypomyces chrysospermus(17%),followed in descending order by the species Hypomyces luteovirens,Verticillium lactarii,Collybia cirrhata(all for 6%).The species Spinellus fusiger,Hypomyces chrysospermus,Syzygospora mycetophila were isolated to be cultivation.
