MYKOLOGOS is a group site for photos of mushrooms, fungi, molds, lichens, slime molds, bacterial mats, algae - all those non-flowering plants that don`t follow the usual rules. I figure ferns are marginal unless they show their sporangia.
PYRO is a community group for photos of fire and burning and campfires and homebrew pyrotechnics. There`s another group for your fireworks photos. Be safe, stay legal, have fun, and share your hot photos!
