Observation 76734: Corallorhiza maculata Raf.

When: 2011-09-18

Collection location: Yosemite National Park, California, USA [Click for map]

Who: Douglas Smith (douglas)

No specimen available

Found under white fir, and pine.

Ok, I’ve got more Yosemite stuff to get through, but I thought I would slap this up quickly, since I have no idea what it is. I was getting some Gomphus floccosus out of the ground under these white fir, and there was a lump to the right. So I started digging in this lump, and I come upon this thing about 6-8 inches down. It seems to be fungal, it is a dense white mass, with protruding fingers in all directions. It has the give to it like fungus, and doesn’t seem to be fibrous like some plant root thing. I’ve got no idea what it is, or might be, just some weird strange growth I found under ground…

Any idea, bring them along.

note jumble of fat-fingered MR at base of flower stalk in linked to photo.

Doug unearthed it before it sent up a shoot. Note Doug’s comment that tissue appeared fungal rather than botanical in origin.

These look closer to a plant than a fungus (to me), but I wonder what evidence Rita has that it’s a mycoheterotrophic plant. That species typically puts up one shoot at a time or a few, and this appears to be getting ready to send up many shoots.
