Fungal eye infection please help ID

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

I need help identifying this fungi/mold that’s growing on my landscape timbers as well as other woods and stumps outside. It is causing my chameleons to get eye infections and making them weak and sick. Her is an imgur link with a lot of photos (from my Chameleon’s eye swabs and of the fungus). It’s like a very dark green/brownish color, with a velvety texture.

Clearly in a situation like this any identification based on photographs has to be tentative. Also, I'm no immunologist, but of course the infection may not be due to the spores.
It's not too easy to see, but image #4 especially seems to show unicellular rather flattened conidia with a pale equatorial zone. These are characteristic of the genus Arthrinium; see:
Arthrinium arundinis 0a.jpg
Arthrinium species, however tend to occur on grasses (including bamboos), sedges, rushes etc. not on timber. Do the conidia seen en masse in the final image show the characters mentioned above? Is there a potential supply of grass-like material, hay or similar, stored near the chamaeleons? Is all this happening in the UK?
Arthrinium is not one of the principal "problem moulds" normally associated with allergic or worse effects, though fungal spores in sufficient quantity are to be avoided.
