A nice corticioid on a small twig in the mixed woodland, maybe Birch or Fagus. Possibly even Pinus. This species seems to be happy on various substrates. The Sistotrema's 6 sterigmata were quite clear from the off, mercfully and it keyed out nicely in Ellisx2, Bernicchia and even CNE.
It's curious to see such skinny sterigmata topped with sub-globose spores. This arrangement- the circle of spores - presumably gives it its epiphet
diademiferum, with a diadem being a royal crown, though you would imagine that could apply to any
Sistotrema or
Botryobasidium.
Sistotrema "bunch of grapes" isn't so catchy.
(It has just now been pointed out to me that botryo refers to a bunch of grapes though in reference to the bunched basidia - thanks SB)
