Aspergillus nidulans

The asexual state of Emericella nidulans, Aspergillus nidulans is an easily recognizable Aspergillus spp. when grown in culture. 

The amber colored, short asymmetric foot cell combined with a bright emerald green colony make this an interesting organism.  Under certain conditions it will also produce egg like structures known as Hulle Cells.   Note: There is supposed to be a squiggle above the 'u' in Hulle cells.

The spores do not have a unique structure and would be classified as Asp/Pen like on an Air-O-Cell cassette sample.
