Observation 98622: Elaphocordyceps G.H. Sung & Spatafora

When: 2012-06-28

Collection location: Mission, British Columbia, Canada [Click for map]

Who: Psylosymon

Specimen available

This was found in a mixxed conifer forest of cedar and doug fir.
Growing through step moss.
I had a feeling I knew what it was so I was careful to excavate the whole thing and to my delight there was a truffle under there!
An Elaphomyces species of some kind. I ve always wanted to find something like this so I am really stoked on the find!

There was yellow rhizmorphs throughout the dirt and eating up the small cones in the duff.


Proposed Names

79% (1)
Recognized by sight: i knew it was a Cordyceps of some kind, but Inski showed me Elaphocordyceps
41% (2)
Recognized by sight: A good margin between the stem and head. It’s hard to tell the colour of the mycelium, which should be white. I see no sign of yellow, but it could have been eaten by the parasite seen at the base of the stem. Yellow rhizomorphs in the soil around is probably another fungus.

i gave this specimen to Daniel Winkler when he was in town last week. So maybe he will find out exactly what it is. He thought it was Elaphocordyceps capitata.

Elaphomyces does have yellowish mycelium.

So there is probably Elaphomyces present in the area.

In your area Western Red cedar probable. Western Red cedar one of the very few trees which doesn’t associate with mycorrhizal fungi. So Douglas-fir probable host tree here.

After looking carefully at the sectioned Elaphomyces, I can’t even tell it is Elaphomyces. Does not appear to have visible spores. Very unusual.

So maybe (just maybe) the host is not Elaphomyces here.

Slice the Elaphomyces, too.

May Elaphocordyceps appear to be species-specific to the Elaphomyces. While the Elaphocordyceps is likely going to have altered to Elaphomyces to the point of non-recognition to species, still it should be possible to either state the E. muricatus or E. granulatus “group”.

there was both yellow rhizos and white rhizos so its really hard to say. i will be looking into your suggestion though, thanks so much for looking!
