of Burt’s Telephoraceae of North America last summer and am just working my way through it.

now I see clear again :)
But in all collections of C. laeve I never ever found any encrusted cystidia/ cystidioles/ cystidia-like hyphal ends. Maybe there is a distinct species in America? I am not familiar with the actual distribution of this species. Also I would love to have literature on American Corticiaceae if available. I am sure there is much work left on this.

Sorry to create confusion

I am speaking of collections of this fungus that we have made here in NYC. My microscopy is, of course, on these collections, not yours. A little history on our collections. Gary Lincoff found a stick with this fungus on it in Central Park, February 2010. Posted it to Facebook and got a couple of responses. One from Tom Volk suggested that the fungus was in the genus Gloeocystidiellum. John Plischke concurred. I did microscopy on this specimen and on a collection I found a few weeks later. It just didn’t key out well in Gloeocystidiellum (in MycoBank). Recently, Gary suggested I look into Cylindrobasidium and indeed, laeve seems a perfect match. And thus my confusion on the synonymy followed.
It is interesting to note that the description of Cylindrobasdium in MycoBank, does not include any encrusted cystidioles; I mentioned Burt’s inclusion of these as a possibility.

What do you mean with your microscopy?

Now I am confused.
These pictures show a find that I made here in Austria and you could not have scoped it.
And when I go to MycoBank and put PENIOPHORA LAEVIS in, I do not get to Phanerochaete but to Cylindrobasidium.

Now I am really confused.
But that does not mean that my observation is not C. laeve. It is ;)

checked the path of my inquiry. Started with Cylindrobasidium laeve, brought me to a synonymy with Peniophora laevis (Burt) whose book I used as a reference for description. Checking Index Fungorum returned Phanerochaete laevis as the current name. I’m confused.
My microscopy showed some encrusted Cystidioles which Burt says may or may not be present. In all other respects the microscopy is comparable.
I should note that the photos in MycoBank are an exact match.

First of all,

these finds are from Europe,
and secondly,
these are Cylindrobasidium laeve (or evolvens as some call it). No incrusted cystidia present.
But thanks for your input.

appeared in a few collections made in New York City parks. Microscopic observations confirmed the ID.
