We've had a lot of rain around here lately, and most yards are mushroom fields. I was keeping my eyes open for pretty toadstools but I found one somewhere unexpected on day 182.
This post is near the parking lot at work, and the combination of textures really appealed to me. I had my macro in the bag, tossed it on the 7D and took a few shots. Somehow or another I blew the focus on this one slightly, but I think that it still works.
The choice to go monochrome came from some advice I read elsewhere. Going mono removes colour from the equation and makes the composition and detail the focal point of the image, in this case (hopefully) enhancing the textures in the shot.
