摘 要:We report the results of a survey for myxomycetes in the Chinese province of Xinjiang,covering the northern part of the Tarim basin and the eastern Tian-Shan *** in the hyperarid Tarim basin focused on monospecific Tugai forests;these are park-like stands of the phreatophyte Populus *** a transect from the Tarim basin to the mountains,trees vanish outside the basin,but reoccur at ca.1,400 m elevation as monospecific forests of Picea schrenkiana;the second focal area of the *** a total of 362 substrate samples(245 from the Tarim basin,177 from the mountains)we obtained 477 determinable records of myxomycetes,plus a total of 206 field collections,the latter almost exclusively from the spruce forests in the *** the 80 taxa recorded 53 are represented by field collections,and 32 were found in moist chamber cultures;with a very low overlap in species assemblages found in the field and in *** receiving less than 50 mm annual precipitation,corticolous myxomycetes were common in the Tugai forests,with Physarum pseudonotabile ***.,Didymium anellus,Echinostelium colliculosum and Protophysarum phloiogenum as the most common *** to the Tarim basin(21 taxa)the mountains were much richer in myxomycetes(75 taxa),although the diversity recovered from cultures was comparable(21 vs.28 taxa).Most species from the mountains fruited on decaying spruce,often collected under or even inside the logs due to the extremely dry *** results suggest first that there is no lower limit of annual precipitation for myxomycetes,as long as at least some days with nightly dew fall allow these organisms to complete their life ***,the two examples of surprisingly diverse myxomycete assemblages from monospecific forests demonstrate,that species richness of this group is not necessarily connected with plant diversity of the *** survey is the most eastern of a large-scale study of myxomycete diversity throughout M
