Aspergillus sp.

Possible ID: Aspergillus sp.

 

Classification:

Phylum: Ascomycota

Class: Eurotiomycetes

Order: Eurotiales

Family: Trichocomaceae

Genus: Aspergillus

 

Isolation and culturing methods:

Isolated from soil that was collected near senior apartment #4 on February 25th of 2018. A small amount of the soil sample was serially diluted with water and placed on several malt extract agar plates. After being stored at room temperature for a week, hyphae from serial dilution C were transferred onto two new MEA plates in order to ensure that a pure culture would be obtained.

 

Culture appearance and growth:

Fungal species was a somewhat blueish-green fungus that grew relatively quickly, almost covering the plate within two weeks. Fungus had a fuzzy, carpet like texture. Hyphae were septate with no clamp connections and were around 3-5 μm wide.

Growth after 2 weeks:                      Growth after 1 month:

         

 

Spore production:

Conidiophores were dark and spherical, or globose, in shape. These structures produced conidia that were also globose in shape and measured around 3 μm in diameter. While producing a dark outline when clumped together, these asexual spores were clear with a slightly greenish tint to them when they were alone.

 

*Microscopic images were taken at 400x, and the screenshot of the first image was taken for emphasis on septa and conidiospores.
