Lecanora argentata

Spores of all Lecanora are simple, that is one celled or not divided. In addition, the spores of the genus are hyaline which, in a strict sense, means transparent. But most references use this term interchangeably with colorless. Under the microscope colorless spores will often appear greenish which accounts for the spores shown to the left. Lecanora argentata is found on bark or wood.
