The provided image shows spores of a thin white resupinate polypore mushroom. The spores are light yellow with grayish tints and have an elongated shape, being roughly twice as long as they are wide. They appear to be arranged randomly across the surface.

The background is blurry but seems to show a piece of wood or bark. It is not possible to determine from this image if these spores belong to one species or many different ones. However, given their similar color and shape, it's possible that they belong to closely related species within the same genus. – AI vision
