Proposed Names

-46% (4)
Recognized by sight: Lobed, blunt margin, felted cap surface, overall pinkish colors on cap and pore surface.
Used references: Bessette, Bessette, Fischer
6% (7)
Recognized by sight: rosette form at eh base of a tree, white pores. +/- orange top. This is a rather young specimen, but it fits pretty well with the concept of L. cincinnatus. This species is misnamed as L. persicinus in B/B/F. It was also known as Laetiporus sulphureus var. semialbinus. This is a bit of an odd specimen as it is not usually so flat this young, but it still fits within L. cincinnatus.

After looking at pics on the net the last few days Im no longer positive of my first ID.

I’ve viewed this

on two different monitors, and the colors appear different from one to the other. Here on my Dell office monitor, there is less gray/tan/brownish and more pink/orangish.

Meriplus or Sulphur

I pick Meriplus every year from the same area.I have watched them from the very first start of fruiting to the very end.Older Meriplus I have found dry out and are thin at the edges.While the Sulphurs which I pick by the pounds also always are thick like this on its edges.Ive done alot of research on both species because I find them facinating.Unless the exposure in the last pics is off my opinion is they are Sulphurs.

Thanks for the input everyone…

I can’t say I’m any less confused, but at least I don’t feel so bad about it. I find what I’m sure is Meripilus in this area at this time of the year and others I’m not so sure about. My main contention here is the thick, lobed margins which doesn’t fit Meripilus sumstinei as far as I’m aware. Admittedly, I’m not a master of Meripilus morphology. The cap texture seems somehow different too. Could these be young specimens?

must note that we have noah, tom, and walt

looking at a ‘fool-proof four’ mushroom which they have seen hundreds of times, and are in dispute. I agree with noah on meripilus, but blew up the picture and dont agree that the dark spots are staining though

this looks just like young Meripilus sumstinei… It’s starting to go black on the holes on the left side on the second photo.

is a Southern species. I am not aware of any NY records.

Sorry, no.

I pulled the name out of B/B/F’s book after seeing a picture here…

The picture on the site and the description in the book match pretty well and the thickened edges of the caps in this observation had bothered me for awhile, so I thought I’d propose it and see what you guys thought.

Super interesing Bob!

I have not heard anyone on the east coast even mention this species. Maybe i have seen it before and never gave it a second thought as to being other Laetiporus species. I have not heard Lincoff even name drop this one. Can you shed any light on it? Thanks!
