9. Type C was from Aegilops longissima, Aegilops sharonensis, and Aegilops variabilis and had Anchusa aggregata, Anchusa undulata and L. arvensis as aecial hosts.

10. The rust Puccinia andropogonis (Schwein.) was studied on its aecial and telial plant hosts, comandra (Comandra umbellata L. Nutt.) and big bluestem (Andropogon gerardii Vitman), respectively, in a native prairie to investigate the influence of aecial host proximity on disease severity of the telial host in a natural system.

11. Comparisons of phenotypic diversity, distribution of specific virulences, and differences in specific virulences among phenotypes were made between the progenitor uredinial populations and the derived aecial populations.

12. In addition to host specificity, characters found useful in species delineation were urediniospore and aeciospore size and shape, and ornamentation of spores and the aecial peridium.

13. Stalactiform rust (Peridermium stalactiforme Arth. & Kern) is accepted to be the aecial state of Cronartium coleosporioides; there is no evidence of its direct spread from pine to pine.

14. Mean rust severity on big bluestem was regressed on the number of aecia on comandra (aecial density) within eight distance intervals from big bluestem plants.

15. Genetic analysis of C. ribicola isolates from different aecial and telial hosts provided no evidence for genetic differentiation and showed similar levels of expected heterozygosity within a geographic population.

16. Annual timings were related to spring weather variation so that discharge peaks each year coincided with shoot elongation of the aecial host, balsam fir (Abies balsamea (L.)

17. Furthermore, differences in both telial and aecial host species, in teliospore dimensions, and in amount of nuclear DNA indicate that subgroups within Group II are beginning to show genetic divergence.

18. The fungus was similar in morphology and host relationships to Tranzschelia arthurii, whose spermogonial and aecial stages occur on H. nobilis var. acuta and uredinial and telial stages on Prunus serotina and Prunus virginiana (subg.

19. There was a significant positive relationship between aecial density on comandra and rust severity on big bluestem that decreased with increasing distance in accordance with the power law model, becoming nonsignificant at distances >40 m.

20. The white-pine blister rust fungus, Cronartium ribicola Fisch. in Rabenh., continues to spread in North America, utilizing various aecial (primary) and telial (alternate) hosts, some of which have only recently been discovered.

21. The differences in the two aecial populations most likely resulted from linkage disequilibrium between virulences generated by host selection in the prairie uredinial population, compared with the lower initial level of disequilibrium in the relatively unselected eastern uredinial population.

22. Development of the aecial and uredial stages of Melampsoramedusae leaf rust of poplar in relation to the phenology of its hosts (Populus spp. and Larix spp.) was monitored from March until October during two consecutive growing seasons in central Iowa, east central Minnesota, and north central Wisconsin.

23. The dikaryotic condition was observed in two cultures from the uredinial stage of P. graminis f. sp. tritici and P. recondita f. sp. tritici, in one culture from the aecial stage of Gy. asiaticum, and in germ tubes from uredospores of Puccinia spp.
