When: 2008-10-10

Collection location: Southeast Portland, Multnomah Co., Oregon, USA [Click for map]

Who: Daniel B. Wheeler (Tuberale)

No specimen available

Hundreds of these, many just coming above the grass level. Most black or so dark brown they are easily mistaken for black, but above the ground and in the sunlight, they are much lighter brown. Distinctive nipple at the top. Only 1 photo shows the fine light brown fibrils on the cap, so used that one first.

Photos don’t get larger

If I click on the photo I get a medium sized one, and if I click on that I get the same sized photo again. Take a look at one of mine, obs 12178, if I click on the photo there I get the 600×800 medium sized photo, and then if I click on that I get my edited 5-6MP photo, which is much larger than the screen, and I cen see more details. That doesn’t happen with obs. which make me think your camera takes rather low-res photos.

With little brown jobs really aren’t going to get anywhere without more details, and usually they need a microscope. Here the top one is thinker and fibrous and looks like other small Telamonia corts that I come across. The other three have the nice conical shape of the Nolanea, and I can’t tell much more, so maybe.

Really, that doesn’t mean much. If you want to know, then you have to get a spore print here, and the Nolanea will be light pinkish brown, and the Cort. with be a deeper rusty brown. Which will give you more to work with there…

Even then, to be sure you’ll need a photo of the spores, and the Cort. will be warted, and the Nolanea will be smooth and angular.

And once you get there, if you want an id, well, then you need a bunch of sources and work, and you still might not get anywhere. Someone needs to do this at some point here, and get back to us, so we can learn also more details.

Each photo can be enlarged by simply double-clicking on it, Douglas. I believe all these were of the same species, although only two were mostly in focus. Smaller mushrooms and I are having a problem: my new glasses are on order, but haven’t yet been received. Unless I hold the mushroom in one hand and take the photo with the other, the camera has insufficient mass to focus on automatically, which results in these out of focus things. They are, however, better than just my descriptions.

I see no cortina or annulus-like area on stipe. Why do you think Cortinarius? Certainly there should be lots of these out now, but this was not associated with an appropriate host tree. This was found next to a flowering cherry; most Cortinarii in my area are associated with conifers.

Two different species here.

The top two photos look like a small Cortinarius, the bottom three look like a Nolanea, sorta… It is hard to tell with the photos out of focus, do you have higher res. photos? It seems like the photos posted are like 600×800, how many pixels is your camera?
