Fungi growing on bread. You can appreciate the two different species (Penicillium and/or Rhizopus) cohabiting, or should I say, competing for the substrate. :-)
Now, if nobody minds, I'll throw away my subject because I doubt that breathing the smell around it is safe. I allowed it to incubate for approx. 2 weeks after it started to sporulate. It is becoming a biological weapon now!
I am happy... :,-)
