1) They can be incredibly, frustratingly difficult to identify!!
2) I don't eat them and have never felt the urge to know what they are because...
3) There are just too many of them. Over 2500 species just in the UK and I'm not sure I'll ever get the hang of ID'ing them.
That said, there are some that are distinctive, some that are very beautiful and if I can identify them, I'll post them on here, as it is a wildlife blog and I like to be inclusive:
|Russula nobilis (Beechwood Sickener): Doug Stannard|
|Russula emetica (or Sickener): R. Harris|
Found under conifers, poisonous!
|Hypholoma fasciculare: R. Harris|
|Calocera viscosa: R. Harris|
|Lycoperdon perlatum (Common Puffball): R. Harris|
They can certainly be very colourful if nothing else.
