  1. That is so cool, are they translucent? Posted 9 years ago
    1. I think it depends on how damp they are, drier they look whiter, wetter more translucent. They are also extremely tiny. The big ones are maybe pin head sized. Posted 9 years ago
  2. Hi morpheme,
    did you do microscopy of it?
    Posted 9 years ago
    1. No - this was done in forest. I used a macro lens and several extension tubes. Posted 9 years ago
  3. I was asking for microscopy for looking "inside" the fungus for proper determination.
    Did you take a sample with you? Was it on ash leave?

    best regards

    1. Ah - I understand. No I didn't collect any samples (though I know where to get them if you want one ;-} ) From my usual sources, I was under the impression that this should be the only species found in this area that is white and grows on twigs, but I do understand that they may leave out species that they simply don't have data on, so there may be other species in this area that are not listed.
      They were not growing on leaves, but rather on very small twigs, as might be found at the very ends of branches (the other tiny white fungi I found that day, Calyptella capula were on the stems of leaves) . I think they were ash (Oregon ash is found here), but the forest in this area is quite mixed - birch, beech, alder, maple and others can all also be found and the duff here was very decomposed, so it would be impossible to say for sure.
      If you think this is incorrect or indeterminate, I will certainly remove the ID.

  4. Hymenoscyphus is a good guess. But which one, only microscopy can tell.
    If you add ATgmx.de to my nickname you can contact me for more information.

  5. just an example: http://mushroomobserver.org/observer/show_observation/65161
    This collection was made not far from yours. But this is also not H. albidus. Host and sporeshape do no fit.
    I don't know a true collection of H. albidus or fraxineus from the American continent.
    However, I would be eager to examine a collection of yours.

    1. Indeed - mushroom observer is an interesting idea, but it doesn't get enough participation to be useful.. I have posted things there with no one ever giving input.
      I did read that we do not have H. faxineus here (thankfully as it kills trees!), but otherwise, though there are many species, there's very little information is available about distributions and details.

      I'd be happy to package up and mail samples for you (I'll contact you directly about this). I hike a lot, so have many opportunities. If you study other small fungi, I've a good nose for finding them and they are tiny so a package could hold a few :)
