Another member of the Aspergillus genera often found on damp building materials is 
Aspergillus versicolor,  It is very closely related to 
Aspergillus sydowii.  The colony color is light green with a few other pale colors mixed in compared to 
Aspergillus sydowii's deep blue green.
Both 
Aspergillus versicolor and 
Aspergillus sydowii have small 
spathulate heads.  They are shaped like like a tiny Dairy Queen malt spoon.  They will also produce conidia from structures that resemble 
Penicillium spp. 
The spores do not have distinguishing characteristics and are identified as Asp/Pen like on an Air-O-Cell cassette sample.
