Tissues (in KOH solution) of fallen from a tree bushy ...

The image shows a microscopic view of tissues from fallen beard lichen (Usnea strigosa), collected on Caney Creek Trail (Little Lake Creek Loop Trail) in Sam Houston National Forest north from Montgomery, Texas.

Tissues are shown in KOH solution. The background is light gray with black lines. There are small green dots scattered throughout the image. The image appears to be a microscopic view of the cells and tissues of the beard lichen (Usnea strigosa). The green coloration suggests that these structures may be chloroplasts or other cellular components involved in photosynthesis, which is consistent with the fact that this organism is a type of lichen, a composite organism made up of fungi and algae. – AI vision
