Fig. 8. Variations in ascocarp morphology of Morchella esculenta from central South Dakota.
The morels in the top row were thin-tissued, and in the bottom row, thick-tissued. Evidence indicates that the variations were phenotypic, but not genotypic, adaptations for coping with wet or dry weather. The height of the lower left morel was 70 mm including the stipe.
(Note. Gene pools must be homogenized in local areas; and therefore, the morels must all be genotypically the same.)
