| 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 the underground "deer truffle",
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".
