How to fix a multiple white dot problem?

I would very much appreciate knowing what are and what causes the many white dots in this example image. And, how does one either not get them, or fix them. Presently, I'm simply using PSE's Spot Healing Brush, which does a good job, but takes some time. Thanks.

Could it be that there are pale-colored tiny particles in the scene that reflect a lot of the ambient light? Cameras are prone to amplify dust and specks that one doesn't notice with the naked eye.
Some photo editing programs have features like impulse noise removal or speck removal, that can automatically remove small specks, although this usually only works if the specks are only a few pixels wide.
 
Flycaster, I think we could all get a better idea if you would shoot a blank gray card, or a solid neutral color wall, something less busy so we could see the white spots better. We still might not know what causes it, but at least we'd be clear there's a problem... :)
 
The only white dots I see is fungus/spores growing on the damp leaf litter, not sure if thats what you are talking about or something else as per RBIV
 
Could be fungus spores and/or ambient light reflections. One thing for sure, I do know that the white spots are not related to something within the camera and are coming from the environment (no need for a gray card, but thanks for the thought.) So, I guess I'm relegted to using PSE's spot healing brush.
 
One way is to use camera RAW and max out highlight and white recovery.
I can edit your pic if you like to see how that works.

I brought the RAW (always shoot RAW) into PSE RAW and maxed out highlights and white. Resulted in very little reduction of the white spots and then adjusted the histogram so that it looked fairly good. Then took the image to PSE, selected the lizard and inversed and used Noise>spot (Radius=2 to 3,) but that just mushed up the background and very slightly reduced the white spots. Again, the only way I got rid of the white spots without messing up the image was to use PSE's healing brush.
 
Is it possible to post the image with no post processing done so we can see what you are battling against please?
