I do recognise Penicillium, but it looks like there are a number of other genera growing on my plates - perhaps Cladosporium or Aspergillus?
Dear Dr. Aktas,
It is difficult to identify such fungi visually, some of them are mixed cultures seems to include Cladosporium and/or Fusarium dominant one in plate number 6.Please make a photomicrographed specimen examined with 100 x oil immersion.Plate 2 most likely to be Penicillium.Thanks
Thanks all for the answers. I am aware of the difficulties of specie identification from culture plates only, but this is unfortunately all we have.
Any how all of the species growing on the plates seems to be air-borne microbes.
There is probably Aspergillus versicolor in your plate nr. 2, besides Penicillium. The dark colonies in nr. 3 are Cladosporium spp. Nr 5: many small Cladosporium and several Penicillium. The big black one is Aspergillus niger, and the big fluffy one is probably sterile, but it coul also be a basidiomycete. Look at the fungi uner the microscope to confirm. It is not as difficult as DNA scientists make us believe :-)
the black colony is either rhizoctonia or aspergillus.. and blue/greenish colony appears to be penicillium.. and most probably the white colony dos not bear any sporulating structure.. Upload some microscopic view for proper identification
The dark colony in Plate no.6 seems to be Aspergillus sp., but it would be helpful if you provide some clear pictures after preparation of slides stained with lactophenol cotton blue.

Please stain them with lactophenol cotton blue and provide the microscopic pictures. Fungi are very diverse organisms and have different developmental stages so it is hard to visually identify most of them.
Plate No 4 contains Penicillium (blueish colony, Aspergillus paraciticus (dark green colonies), Fusarium (whitish colony), and Alternaira blackish colony)
