This little 'polypore' used to be known as Polyporus arcularius and like so many plants and fungi taxonomic work has resulted in a name change! This is a distinctive little polypore, for if you look at the pores they are of an angular composition sometimes referred to as 'coffin shaped' that are pale often creamish in colour. The cap is usually indented in the centre and covered in fine flattened scales usually a pale brownish/greyish in colour. They often have a row of fine hairs radiating out from the edge of the cap. I have often found they are one of the first fungi I see after winter. An early herald for the season ahead. Well let's hope anyway. Lovely clear image of the cap surface.
