I've put a few of my pictures together to help people ID mushrooms. I'm no expert at all but have great friends that know their stuff. Have a click Searching for Mushrooms It may interest you.
Some excellent shots of mushrooms on your link Kildale. Fungi fascinate me as there are just so many different shapes, sizes and colours.
