I am not at all sure what this little mushroom is but it was 2mm tall, I used the 60mm macro lens and 2 extension tubes. It took me several attempts to get the whole of the stem in focus. This is 55 stacked images during my attempts I made 100 stack and 200 stack only to find I had not got the optimal magnification to start with. I deliberately underexpose to ensure the whites were not blown, they are far from that and yet the surface of the little mushroom still looks bright - must be in part dur to contrast. I am hoping more little mushrooms will grow and I will be able to get a more pictorial aspect to show. Looking at the lower front edge of the dome, I am not sure if I really nailed the nearest point of focus.
