Observation 71029: Monotropa uniflora L.

These myco-herotrophic plants are sprouting up everywhere in this small canopy of Western red cedar, Douglas fir and Hemlock trees. We tend to come across a large abundance of various Russula species in this canopy in late August to November.

Note the first few images that show the rhizomatous/mycelial cluster that the Monotropa has attached to-and is gaining nutrients from.

The 4th image shows young specimens along with dried- black specimens (in my hand) from last summer that still remain nearby.

Mainly R. brevipes and R. xerampelina fruit in this canopy in fall.

are listed as common symbiotes with monotropa in multiple sources. I have photographed and collected R. xerampelina and R. brevipes from that exact spot for multiple fall seasons, and When I pulled up the single flower this entire clump of threads/dirt and buds of small Monotropa all came along for the ride. I have only experienced the same activity when pulling up an ectomycorhizal, mycorhizal or hypogeous fungi. I still could be wrong, but pretty confident that the host species of fungi for these Monotropa are Russula.

Great observation!

How can you tell that it is attached to a rhizomatous/mycelial cluster? I know this is supposed to happen, but how can you be sure this is R. or any other mushroom?
