@ Chakola if you are able to show an image of the lower surface of this fungi, identification will be more accurate, however, from these I suspect this may be Lentinus fasciatus (Hairy Trumpet), rather aged and showing signs of algal invasion, but I'm not completely certain.
Hi Teresa, next time I see one of these (infact will do this for all future fungal sightings) Illinclude an underside shot, thanks. I'm a keen photographer but new to the uploading / identification process. Nick, Chakola
