I destroyed images 1-2, and agree that the collections should be kept separate. I will endeavor to do so in the future. I now realize that I mixed the two species and thought that the poroid ones became tooth-like. Good lesson.

Two things:

1. Fruiting bodies from separate trees should be treated in separate observations unless it is amply demonstrable that they belonging to the same sp. and deserve to be treated as a single collection/observation. In this case, taking fruiting bodies from different trees appears to have resulted in collection two distinct species of fungi, unless I’m wrong about the development of the hymenium of Climacodon vs. Climacocystis. Either way, good collection practices favor segregation of material over combining/mixing.

2. The images most clearly showing pores have been removed, but the fruiting bodies in those photographs are the same as those in images one and two. AFAIC, the observation is still mixed.

Dave as far

as I can recollect Sandy and I were following our guide and I noticed these on the Hemlock tree. I took photos of the caps first and then pointed the camera up for the second series of shots. Upon walking around the tree I saw more on this and another tree which I photographed. Upon returning home I placed some in a planter and took more photos. My original observations were that some species had pores that were becoming teeth. My original description was written the next day.

against the mixed collection proposal due to destroying two photos of poroid species.

I had read…

the original notes for this observation, but forgot about your description as the discussion developed, and I got more interested in trying to understand what I was seeing in the photos.

The remaining three photos show harvested specimens with fertile surface consisting of spines. So the original notes appear to not fit these photos.

Phil, are you certain the first two photos show the same fungus?

on my original proposal, which is why I proposed Polyporales. The two I removed were poroid.

Actually, I was not convinced…
By: Dave W (Dave W)

that any of the photos (including ones removed) showed a poroid fertile surface.

Immature Climacodon with tightly packed spines can appear poroid, even smooth near the cap margin, obs 174619… especially when one factors in photographic resolution.

But, having said this, IMO the photographic information (previously) provided was insufficient to either support or rule out a poroid surface (on what may have been a different species than seen here).

Destroyed two photos

of species with pores.

It is my understanding
By: Danny Newman (myxomop)

that Climacocystis’ pores can become “irregular,” mazelike, jagged, etc., but will never develop into slender, segregate, pointed teeth, as in Climacodon and other truly “toothed” fungi. The images here show one clearly poroid fungus and one clearly toothed one.

Danny, Phillips describes Climacocystis borealis…

as having pores and tubes. Like you pointed out, fertile surface here appears to be distinctly comprised of spines/teeth.

I thought about proposing Climacodon pulcherrimus, but I haven’t ever IDed this species first-hand.

Hemlock seems like an interesting host for this.

Nice job on the photo-documenting, Phil.

toothed, not pored
