Unclassified conidia are not classified as any of the recognized spores. They have a definite edge making it look "spore-like". Some commonly seen unidentified conidia are a spore that resembles an octopus with a large body and tentacle-like arms radiating from one side of the spore or a brown to black spore that resembles a four-leaf clover. Generally these spores can be cultured for definitive identification.
