The image is a microscopic view of mushroom spores that were extracted with KOH (potassium hydroxide) and then stained to make them visible.
The background is white, which may be due to the slide being prepared on a microscope slide. The spores are oval-shaped and light yellow in color, each measuring around 5 micrometers by 2 micrometers. They have smooth edges with no discernible ornamentation. Due to their size and shape, they resemble the spores of Psathyrella species (formerly known as Homophron).
The spores were collected from a mushroom growing at the base of a hackberry tree in Lick Creek Park, College Station, Texas on November 15, 2023. – AI vision
