Oyster Mushrooms
there is a
great online guide for mushrooms here:
Roger Phillips - Mushrooms
Moonraker, I don't know if it's just me but I couldn't use the link to rogers mushrooms. It all seems correct but won't find it

Annoying because if it's as good as his books I want access!
Great write up on the morels BTW
Tested and working when I posted and just now too Marts. Weird. You used to have to pay but it is free access now and has all the info and photos of the book but more
Try to cut and paste the direct url:
www.rogersmushrooms.com
or the main site with links to this and also one on Roses, others to follow it says but not sure if that is still going to happen as it lost money as a business. In a reply to a message, Roger Phillips says it will become a registered charity next year to keep it going which is good news.
