Peachysteve and myself had a walk with the dogs around the water and found the species of fungi that are pictured below.
Tear Dropper (Cylindrobasidium laeve) above and spores below.
Spores pip/tear shaped, 8.8-12.1 x 5-7 microns.
Leafy Brain (Tremella foliacea).
Exidia plana - Steve's photo. The white coloured specimens were underneath the bark. It is probably exposure to daylight that turns them black.
Silverleaf Fungus (Chondrostereum purpureum) - Steve's photos above and below.
Common Tarcrust (Diatrype stigma).
Spores 10-12 x 1.5-2. 2-guttulate, slenderly allantoid, pale brown.
Scarlet Elfcup (Sarcoscypha austriaca). They are definitely spreading everywhere in Calderdale.
Chaetospaerella phaeostroma - above and spore below.
