I've always liked close-up photos of plants. These photos were taken in my woods. These mushrooms would be wonderful spots for a fairy to fly past, or sit. Or these could be used as wall-art in a 3D dwelling.
Mushrooms I find are usually addressed as "oooh! pretty!". No, I don't have a good manual for identifying the mushrooms that I actually see. The books I have mostly show photos of mushrooms I've never seen. So, no, I don't know their official names, sorry.
As merchant resources -- these could be used as clothing textures, as wall murals, or other places where a backdrop of a large mushroom is appropriate. Or as a reference for making models.
Six photos are at 4000x3000 (or 3000x4000) which is 12 megabytes, and 180 dpi. One is 2848x1896 (480 dpi), which is 5.4 megapixels.
Drop shadow is ONLY in the promos, and NOT on the actual photos.
