Editor's Comments April, 1990 First announce-: David J. McLaughlin, Department of Botany, University of Minnesota, St. Paul, MN 55108, is the new Editor-in-Chief of Mvcolouia, succeeding Ron Petersen ; Kudos clearly are in order for the outstanding job done by Ron Petersen and his staff at the University of Tennessee. Good luck, Dave! Thanks for the kind comments from several of the MSA members who sent them to me after the October, 1989, issue came out. With this second issue prepared here at SUNY-Oswego, I wish to acknowledge the assistance of three undergraduate students who provided much logistical help for both issues, seniors -- Jennifer Collart and Monica Converse (paid with Newsletter support funds) -- and the frosh, Melissa Matolchi (a work-study student assigned to my laboratory). Those three spent many hours labelling, stuffing, sorting, bagging, handling, and doing other kinds of dog-body labor, and I could not have done without their help! I also want to thank June Johnston, Director of SUNY-Oswego Publications, and her assistant, Jody Longeill, for their valuable advice and quality work. The Newsletter was something of a new challenge for them and their staff, and I think the results have been excelleht. There are a couple of minor changes in the blue Newsletter Questionnaire (corrected typographical errors, a rearrangement of some items, and a new item -- New research projects). I think I have it about right, but suggestions for change are welcomed. There are three inserts: A. The M A Newsletter Questionnaire (blue) B. The Ernployee/Employer Data Form (green -- new address for Bob Pohlad) C. An MSA Newsletter Survey (yellow) I arranged the Abstracts of Papers and Posters presented at the Annual Meeting of MSA immediately following these comments. The Abstracts are listed alphabetically by the first author; additional authors are listed alphabetically following the listing of Abstracts (pages 46-48). The remaining pages (49-68) are from the MSA Newsletter Questionnaires returned since the October issue, 1989. Since I typed those pages where typing was needed, any errors are my fault, and I apologize in advance. It has been a pleasure preparing the past two issues. However, since I am not sure whether those two issues have been able to meet the needs of the membership, I have included a survey as an aid to preparation of future issues. Please respond. I want'to make the Newsletter as good as it can be (within my limitations), and you can help. Also, if you have suitable items (artwork, anecdotes, etc.) which can function as page fillers when there is a need, please forward them to me. Best wishes; I hope to see you at the meeting in Madison. Sincerely, 7&mLL.e Terrence M. Hammill, Editor MSA Newsletter

VA mycorrhizal fungi associated with a single subspecies of plant. Basin Big Sagebrush, were collected over the entire range of its distribution during the growin6 season of 1989. Sites sampled range@ from Baja California. Mexico to British Columbia, Canada, to North Dakota, to New Mexico. Ten 3 cmxl0 cm deep cores from different shrubs were taken at each site and analyzed for VAM fungal species composition and density, % root infection, soil water and soil P. G)omus was common among most sites. The fungi were predominantly GI. trom the Baja Peninsula and across the desert through California and New Mexico. Sjlomus tonuosum was common in Nevada and Baja California. GI. predominated in the central Great Basin. GI, was common from British Columbia to North Dakota. Glaaswra was common in North Dakota. Scutelloswra extended from southwestern Wyoming across to Reno Nevada. -. were common across New Mexico. Nevada, and California. There is a wide diversity of VAM fungi associated with a single wide ranging plant subspecies. Thus, the species composition of fungi appear to be regulated in part by habitat. - Z. -Q. AN, J. W. HENDRIX, D. E. HERSXMAN, and G. T. HENSON. Department of Plant . Pathology, University of Kentucky, Lexington 40546. Endogonaceous mycorrhizal community associated with soybean as affected by crop rotation and soil fumigation. Propagules of mycorrhizal fungi in a Western Kentucky field highly productive for soybean and previously planted for two years to corn, milo, fescue, or soybean were determined by HPN bioassay before and after fumigation with 67% methyl bromide-33% chloropicrin and throughout a season in the production of a crop of soybeans. Twenty species of Endogonaceae, mostly Glomus species, were found. In soybean plots, soil fumigation eliminated most propagules in the upper 15 cm of soil; but after production of a crop of scybeans, populations of total propaqules recovered to prefumiqation numbers and were higher than populations in non-fumigated soil. Soil from plots grown continuously to soybean had fewer species and lower populations of propagules of Glomus spp. than plots rotated with the other three crops; however, populations of Giuas~ora spp. were high in continuous soybean plots. Populations and number of species were higher in fescue plots than in the others. Colonization of roots did not become extensive until about eight weeks after planting, about the time plants entered the reproductive phases. D. A. ANDERS and J. C. ZAK Ecology Research Group, Dept. of Biological Sciences, Texas Tech University, Lubbock. -. TX 79409. ~ ~~~ ~ species abundance and seasonality of wood-decomposing basidiomvcetes from woodrat middens in the Chihuahuan and Sonoran beserts. Woodrat middens may function as important centers of wood decomposition in desert ecosystems. This smdy examined the spatial and temporal occurrances of wood decomposing basidomycetes on wood from middens in the Chihuahuan and Sonoran deserts. Distinct temporal and spatial variability in numbers of species and species composition were observed. The majority of basidiomycetes from both deserts were isolated during Aupst. A greater number of species were isolated from middens in the Sonoran verses the Chihuahuan desert at all sampling times. Although the two deserts shared species in common, the fungal species composition of middens in the Sonoran did differ from the Chihuahuan. Penio~hora ramaricicola was predominately found in the Chihuahuan rather than the Sonoran. Differences in the species composition of the basiaiomycete assemblages assiciatea with woodrat middens could result in differing wood decomposition rates between the two desen ecosystems, and the importance of middens to the overall decomposition of wood.
