Two previously undescribed sporocarpic species of Engogonaccae were found in prairie samples but have not been successfully established in pot culture, leaving the genus to which they belong unclear. Though variable, 11-50% VAM root colonization was evident in all prairie grass roots sampled throughout the year. In contrast, no identifiable VAM root colonization was evident in wheat until May after flowering when 27% root colonization was observed. During the 1981-1982 growing season, roots of two other wheat fields were sampled with similar results. No colonization occurred until May when 8% root colonization was evident. The possible influence of such low levels of root colonization occurring quite late in the growing season of winter wheat is discussed</p>10afungi10atallgrass10awheat1 aHetrick, B.A.D.1 aBloom, J.  uhttp://knz.lternet.edu/content/vesicular-arbuscular-mycorrhizal-fungi-associated-native-tall-grass-prairie-and-cultivated
