Northern Hemisphere Cordyceps

 


 
Elaphocordyceps capitata (Holmsk.) G.H. Sung, J.M. Sung & Spatafora = Cordyceps capitata (Holmsk.) Link 
"The new genus Elaphocordyceps is proposed for a subclade of the Ophiocordycipitaceae, which includes all species of Cordyceps 
that parasitize the fungal genus Elaphomyces and some closely related species that parasitize arthropods"  (Sung et al. 2007).
Update: Quandt et al. (2014) transfered all Elaphocordyceps to Tolypocladium, thus now 
Tolypocladium capitatum

Formerly Cordyceps capitata (Holmsk.) Link and now Elaphocordyceps capitata (Holmsk.) G.H. Sung, J.M. Sung & Spatafora is growing from an underground Elaphomyces deer truffle species. Elaphocordyceps capita has immersed perithecia and a capitate, darkish fertile "cap". E.capitata is distributed over the whole northern hemisphere.



Here a more typical one headed specimen sliced open for display.

There has been research in China and Japan on the medicinal propensities of
closely related Elaphocordyceps ophioglossoides, which seems to have estrogenic substances.

I am not sure what causes the growth of 5 heads from one Elaphomyces granulatus-deer truffle, but I have observed in Ophiocordyceps sinensis that double or multiple heads usually occur after the immature stroma was injured, most commonly fed on by a mycophagous insect. Right next to this specimen grew another one that had half of its stem based chewed off.

Here an even closer look:
A crusty outer layer protects the perithecia, the spore producing organs that contain the asco-sacs are embedded.

 On the East Coast...

Larry Millman found this larva near Boston. The larva (length 2.7cm), probably of a tussock moth, has been infected by Hirsutella, an anamorph of Ophiocordyceps, according to Kathie Hodges, mycology professor at Cornell.
