Observation 403520: Ascomycota Caval.-Sm.

When: 2020-03-06

Collection location: Midland, Michigan, USA [Click for map]

Who: Eric (eozkan)

No specimen available

Discovered this small patch of powdery black mold growing on a brown rice flour “BRF” cake. Assumed it was Aspergillus or Doratomyces…but the spores do not look like those. Spores resemble those of Alternaria alternata “Black Leaf Spot” but I’m way out of my depth here. Spore photos are unstained light micrographs at 400X. Would appreciate help with identification.
