Notes: This was growing under a conifer. At first I thought it to be just another drabby bolete. Then I noticed that they where attached to what appear to be puff balls. I identified the puffball as a Scleroderma. I broke one open and there was a black spore mass. The only thing this could be is Boletus paraciticus.Now weather this is an actual parasite may be debated. I have been examined this site for awhile and although a bolete seems to pop up right out of the puffball the host is not affected. The term parasitic usually refers to organism living at the expense of the host. Case in Point is Cordyceps. If you look at the host of the cordyceps you will notice that the inside of the pupae is full of mycellem/ Where as the Scleroderma appears unscathed by its boletus attached to it. The spore mass of the Scleroderma is still able to release spores . Im wondering if its not more of a symbiotic relationship with each other They benefit each other in some way. Just a thought.

Sclero – thick; derma – skin; so Scleroderma=thick skin. Also known from Washington state near a hot springs (forget which one) on the Olympic Peninsula northern side; but rare here. Scleroderma is rather common, associated with many trees, both hardwoods and conifers. I have found most other Sclerodermas in Oregon, but don’t remember collecting S. citrinum. Kind of think P. parasiticus might also fruit from S. hypogaeum, which, because of its underground fruiting habitat, is also infrequently collected.
we don’t get them out west, so keep those cool images coming!
