Who: nouchit

No specimen available

I first found the smaller two mushrooms in a big grass field kept moist by a sprinkler system. Both were alone and about 30 feet apart. The hood is like an umbrella that would fit right over the pinky finger it is about a centimeter in diameter.The color of the hoods are beige and become brown up until the top. The gills are dark black. The stem is very thin. The second mushroom was amongst a patch, but this one looked a little different. The hood was white and spread horizontal. The outer rim was like a wave going up and down. and it is about an inch and half in diameter. When I picked them, neither of them turned any color (blue)The pics are poor, i know, my camera is old.

Age of camera is not the problem

The actual photos aren’t bad, it looks like the camera can do fine. But you are letting it decide the focus on the shot, and you have the mushrooms held up in front of a much more distant background.

This is a common problem in shooting mushrooms, where you have small things in front of more distant big things. The camera will use its autofocus to get as much in focus as possible, which will mean focusing on the background, giving you blurry photos of the mushrooms.

You can fix this by turning off autofocus. Or forcing the focus by having the auto focus fix on something larger, like your hand, at the same distance as the mushroom, then remove the larger thing, and take the shot. Or not hold up the mushrooms in front of a distant background, but place your mushrooms directly on the background, like a table. But even then, if your focal plane is narrow, it can be hard to get the camera to focus on the right thing.

I have a 2 year old camera, and I have all these same problems. Just something you have to keep in mind for pretty much all mushroom photos.

Look at Panaeolus foenisecii

The first three look like Panaeolus foenisecii.

The fourth is too blurry for me to identify.
