There was a particularly interesting effused or resupinate crust on the dead but still strongly attached branch of an oak tree opposite the drive to the old hunting lodge.
This was definitely bleeding so it should be one of the following two species. However, there are often some considerable difficulties in distinguishing the differences between Stereum rugosum (Pers.) Fr. and Stereum gausapatum (Fr.) Fr..
Stereum gausapatum often appears generally darker and perhaps browner rather than yellower in many images but by no means all. Both are often photographed as a light brown or peachy colour. Descriptions in books are highly contradictory.
According to Buczacki it is markedly wavy and sharp-edged meaning? margin with a paler edge. However I cannot see most of this replicated in any of the Facebook photos, except the pale edge, which may not be totally unique to gausapatum.
Does Stereum gausapatum guttate more than Stereum rugosum? This is certainly suggested.
If the crust is obviously perennial then it is more likely to be Stereum rugosum the only perennial species, that does seem to be agreed.
