* Comments: The majority of the specimens obtained exhibit the typical form of the species, with its white, creamy or gray, long or short cylindrical sporotheca and stalk equal or little over half the total size of the sporocarp.
psittacorum flowers, exhibit a ribbon-shaped pedicle varying in the shape of the sporotheca (fuse-shaped, egg-shaped and subcleaved) and in the total height of the sporocarp.
Some of the specimens obtained in the present study were typical, while others exhibited morphology alterations of the sporotheca and stalk dimensions, attributed to the culture conditions in moist chambers.
Elaborate mutualisms based on fungal inoculation by insects and mites have evolved many times, with spore or yeast pockets called "mycangia" in insects and "sporothecae" in mites being analogous invaginations to the pollen pockets of many fig wasps; to paraphrase Stein (1922), a pollen pocket is a mycangium is a sporotheca
. Perhaps this profusion of terms has contributed to the historical separation of these ecologically analogous interactions.
