Abstract
The 2 weeks field studies during June of 1987 continued work on that part of the previously stated objectives (e.g. McKnight, Harper, & McKnight, 1986) concerned with the inventory of fungal species in the Wyoming national parks, particularly Grand Teton National Park. The specific objectives were to (1) study species of the genus Cortinarius, section Leprocybe, particularly those in the subsection Zinziberati to further clarify species concepts and relationships of species collected earlier, especially those of the 1983 and 1987 collecting seasons; (2) obtain illustrations of species for a revision of the previously published Checklist (McKnight, 1982) and a fieldguide of common species in the Grand Teton-Yellowstone area now in preparation.
