The 2nd pic is better, but the flash has killed it a bit, and the central comp is a bit naff... As a record shot it's great, but I know you want to be a bit more artistic with your photos, so you'll get a slap every now and then!
When you're taking fungi pics, remember to take a waterproof sheet with you to kneel or lie on (bin liner will do), and a piece of ordinary tin foil makes a very portable reflector to bounce light off. If it's very dark, and you can't get a good angle with a tripod, use bounced flash, a gold reflector will warm things up a bit.
Both taken without even kneel
