I have no idea, I only got C for Microbiology :oops: We need more than a picture to identify fungi, I think. I saw my colleague needs an atlas to characterize them while holding the culture :) and I was bothering her identification with my questions :lol: I can see there are more than one, at least two kind of fungi there 8)

Are you sure that there is only one fungus there? If I didn't see it wrong, if you look at it under microscope, you will probably see at least: Aspergillus, Penicillium, Mucor, Rhizopus
If you have chance to send us a mic photo, we can try to identify them. (My fungi lab final is finished about a week ago. ;) )

I said at least two: white colony, yellow colony. Now I think the white one has three different colonies: the round one (on the left), the one with the yellow thing in the middle, and the amorph one... That's all I can see, a ra investigation, I know :lol:

Poison: I think none of your fungi are in that figure. Aspergillus, Rhizopus, and Mucor looked as brown-black colony, while Penicillin looked as blue-green colony..

Well, we observed them on a piece of bread which look white. I don't know... There can be species variations (as much as I know Aspergillus niger (hope I remember right) looks dark-colored) , I mean we are talking about genus. Also the color depends on how mature the organism is.
Whatever, I will rearch for it.

So here are some of the photos I've found: (sending them as 2 posts as max 3 attachments are allowed in one post)

Hope they are helpful. :)

Those color differences are because of species differences and also about how mature the fungi is.

Mucor on peach ( The white ones are probably Mucor-and rhizopus and mucor has slight differences so it can be Rhizopus too. A microscope photo would show that.)

I think no one can identify a fungi which is still in its vegetative stage or under developing state.
Also coloration in one of the important macroscopic means of identification feature of all the fungi.
