Description: Electron micrographs of spores from the bolete-like mushroom Austroboletus mutabilis Halling, T. Osmundson, & M.A. Neve. "Notes: There is a dramatic color shift on the pileus as the basidiomes age: deep red to orange and finally yellow. It may occur as a consequence of time, but may be mediated by exposure to light and/or a fluctuation in humidity. Single basidiomes may exhibit any color in this range. Under the light microscope, the plage appears smooth on spores that are otherwise ornamented with pits and fissures."
