New Species - Blue Edge Pinkgill

I would guess I have in excess of six species of Pinkgill but I struggle with their identification (as do a lot of people). However I can add a fourth ID (following E conferendum, E porphyrophaeum and E griseocyaneum) following the relatively easy ID of the Blue Edge Pinkgill (Entoloma serrulatum). This one has a distinctive colour to cap and stipe and distinctive gills with a blue and serrulated edge. the photo is very noisy as it was taken on highest ISO in fading light but the distinctive blue black colour of cap and stipe can be seen.
