Acrodontium spp.

Acrodontiium spp. on DG-18
The organism, Acrodontium spp. was found to be a laboratory contaminant on culture plates.  The organism is similar to several other organisms.  The colony growth is slow on DG-18 agar with white fluffy restricted growth at 5 days.

Acrodontium spp. 400x (25 microns between 6 and 7)

The lower end of the conidiophore is wider at the base then the conidia producing structure at the tip of the conidiophore.  I identified the organism using the key in the book, The Genera of Hyphomycetes  These spores would not be identifiable to genera on an Air-o-cell cassette sample.
