A rare 5 headed Drumstick Truffleclub - Elaphocordyceps capitata. © Daniel Winkler, Dec. 2011, Found near Florence, Oregon Coast.
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.

A transect of the fertile head of the Drumstick Truffleclub. Elaphocordyceps capitata's stem is clearly distinguished from the fertile tissue containing the perithecia. Note the tough outer layer in which the perithecia embedded. To the left is a close up.

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.
