Hi, I found this beautiful white fungus on the stump of a silver birch, and I’ve no idea of even the genus.
As there was only one fruit body, I just took a thin slice of the cap to get a spore print.
Cap: 6.5 x 6.5cm, convex, white, scaly, flecked with light brown.
Gills: Decurrent, white.
Stem: 30 x 15-20mm, off-centre, white becoming pinkish brown at base, base covered in short fine hairs.
Spores: White, inamyloid, sausage-shaped, 10.1-13.2 x 4.3-5.7um.
Any thoughts would be greatly appreciated.
