Many things which some might view as hassles are in fact what make the process of stalking mushrooms for fungi watercolor art appealing, while other difficulties and technical problems are and always will be just simple drudgery and trouble. There is a certain practical challenge involved in squirming into a moldy patch of forest debris while chasing the perfect angle on a little mycena, but being up close in the natural environment of that mushroom is its own reward too.

When you are out hunting pictures of mushrooms, not only is there often plenty of mud, dust and debris, but there are always lots of fungus spores on the ground and stirred up into the air. It's like a macroscopic encounter with quantum mechanics - because the act of capturing the mushrooms photograph sets the state of the subject. Unfortunately, the fungus spores would like nothing better than to settle inside a camera body or inside the bellows of a lens mechanism.
