The source used on this plate is a water sample I collected from a puddle and it has been diluted. The left photo is of the bottom of the plate, and the right is of the top of the plate. The morphology of the left photo (bottom) is a dark brown/green colour and the top of the fungi is a browny green coloured fungi with a darker border of with a brown/dark green colour. It has a slightly fluffy texture If you look close (hard to see in photo). This fungi looks most similar to Cladosporium herbarum, with similar colouring of the top and bottom and the texture is similar as well.
