INDIANA MUSHROOMS
              Tolypocladium Fungi
Formerly placed in the genera Cordyceps and Elaphocordyceps, these fungi have been
moved to the genus
Tolypocladium (2014). Phylum Ascomycota. The two species
presented here are myco-parasites of underground f
alse truffles in the genus
Elaphomyces.

The club-like head of these mushrooms, called the stroma, is where spores are
produced. Tiny pimples on the stroma represent little spore-producing factories called
perithecia, immersed within the stroma. Known as sac fungi, spores (technically called
ascospores) are made within microscopic sacs called asci. Ascospores are ejected from
the perithecia into the atmosphere through small pores (ostioles).
Note: These mushrooms are now in the same genus as the medically
renowned fungus
Tolypocladium inflatum, from which Cyclosporine, the
anti-rejection drug that made organ transplants possible, was derived.
Separate names for the sexual and asexual forms of
Tolypocladium
inflatum
are no longer used. Cordyceps subsessilis is now a synonym.
See IMA FUNGUS for
details on name change.

George Barron calls the stroma "a massive fungus matrix".
