Description: This species has a C+ yellow thallus that closely resembles that of O. turneri (described elsewhere), but quickly dissolves into a near-leprose crust. Unlike O. turneri, which actively colonises nutrient-rich bark, O. microstictoides grows only on acid bark or lignum. In Ireland, the species is scattered, but not uncommon.

Key Identification Features:

• Like O. turneri, but with grey soralia that develops into a near leprose crust (C+ yellow)
• Only on acid bark and wood.
