Amanita Muscaria has to be one of the easiest fungus to identify. And it is one of the reasons I take a daily walk at the moment, there is often an autumn crop here and I am hoping to find one whilst it is still small to set up a time-lapse camera.

The closest I can find for the second one is Agaricus augustus but I wouldn't eat it unless I was much more certain.

The first one is awkward because I can't find anything which matches with a dark stem.

I think you are right about my mushroom - I think it has ended up on somebody's plate!

LOL - yessomeone enjoyed it for sure ! I agree with your identification on mymushroom. My camera has been sent off and will be with me tomorrow. Must admit they have been quite good about the whole thing and did offer tocheck the camera over but I felt that it was not worth opening it up and pokingaround whereupon something else might go wrong when they put it back together -I'm think of a dirty sensor etc.
I'll just live with it and know that sometimes I will need to adjust a fewpictures. That's the lesser of two evils !

I realise that this thread is a bit old and that you said you were going to live with the problem.

I was beginning to think that my D5500 had a sensor which could detect fungus because my overexposures tended to be when I was taking live view shots of mushrooms. Anyway, I went away for a few days during which time I was at my sister's house and had my camera sat next to me on her leather sofa. Somehow, it slipped off and hit her hardwood floor - fortunately lens hood first. The lens hood needed replacing but the camera and lens seemed to be undamaged; though I am now paranoid about every slight looseness of the lens.

Since I got back, I haven't really taken any mushroom shots with or without live view but today I did and whilst they would not win any awards and the lighting was a struggle, the exposure is significantly better than it was.

I wouldn't like to claim that the knock made the difference as I have also made a number of changes to the settings (not all to my liking) having watched some tutorial videos. Or maybe it was just due to the poor lighting; who knows...

That certainly is a perfectly exposed picture. I wonder if the hard fall has 'jolted' something within the camera to allow the exposure correction. I was told by Nikon that the section inside the camera body that controls the aperture setting can 'sometimes' become bent if a lens is attached incorrectly. Perhaps the fall has allowed this part to be bent into a better shape for exposure. Without taking the camera apart we will never know. I suppose time will tell after a f

I wouldn't say that it was perfectly exposed but it is definitely within tolerance.

And regarding the knock, that's what I thought too but it isn't very reassuring.

On a general note, I'm finding it hard to find the motivation to go out with the camera in present conditions; I love Scotland but the winters can be grim.

It has only taken 18 months but it seems like Nikon have finally done something about this as it looks as if it was addressed in the latest firmware - v1.02:

Nikon | Download center | D5500

• Fixed the following issues:
- The camera would stop responding if the multi selector was pressed right with Add items > CUSTOM SETTING MENU > c Timers/AE lock selected in MY MENU.
- The shutter would sometimes not be released in response to live view touch shutter controls if autofocus was used with an SB-800 flash unit attached.
- Optimal exposure would sometimes not be achieved in photographs taken during live view with lenses that support both autofocus and electronic aperture control (type E lenses).
- If image review was enabled during viewfinder photography, the camera would sometimes display shooting information in place of the most recent picture when the user removed their eye from the viewfinder after shooting.
- The camera would sometimes fail to store the option selected for a Autofocus > a3 Built-in AF-assist illuminator in the CUSTOM SETTING MENU after the mode dial was rotated to another setting.

Nikon support got back to me within 30 minutes ! I'm sending the camera body off tomorrow and will let you know the outcome. See Nikon reply below.
So its beginning to look like they has a solution that seems logical !

(I am sorry to hear of the issue you are having. I canclearly see from the photos provided that it does indeed seem to beunderexposing somewhat when shot wide open. One reason for this and the mostlikely given that it is happening across the board is that the manual aperturecontrol lever on the body is very slightly off and the lever cannot get thelens to its widest aperture even when the camera thinks it should. This wouldexplain the change and darkening in exposure and also why the lenses perform justfine on another body.)
