ID request Reddening Polypore

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

ID request Reddening Polypore

Reddening Polypore - help with id please
It grew as a small cluster out of the edge of a large beech stump in Skipton hospital grounds. When dry it looked all white but with hydration colours developed. The edge is pale and the slightly zonate top is gingery brown.

The cap surface is glabrous and coarsely wrinkled towards the edge

The stem became reddish, turning brownish with age
3 stem and pores.jpg
The poroid surface is deadaleoid with shattered edges to pores near the edge of fruitbody Pores 2 per mm
4 inner pores deadaleoid.jpg
5 outer pores dissepiments frayed.jpg
Microscopy
Spores ellipsoid 5.4-6.0x3.3-4.2 microns

After a long search no basidia to be seen. Hymenium contains cystidioles but no cystidia. Protruding through it are hyphae with broadened ends. Some crystals are dotted through the context.


Structure
Dimitic with solid skeletal hyphae
Generative hyphae 3-4 microns. Clamps very sparse but curious as shown

Is this enough information to make an id? I cannot recognise this in Ryvarden and Melo.

Hi Archie,

Have you considered Abortiporus biennis - (Blushing Rosette) ?

Your find seems to have the right sort of overall look about it.
The pores / pore surface are about right, as are the spore sizes you give.
(In Collins, cystidia are described as cylindrical, wavy with granular content).

Regards,
Mike.
Common sense is not so common.

Many thanks Mike and Adam. That ticks every box when I check mine against the description in R&M. I will go back to try to see where I went wrong
Yours aye

I did not find gloeocystidia until I re-examined the specimen after your identification. Then I found a single one with no granules in it so might not have recognised it as a gloeocystidium. Had I known my specimen had them I just might have got it by keying in R&M.

Thank you both my friends for all your help

Archie
