Description: This ‘bark pimple’ species with a whitish-beige thallus, suffused pink when fresh, is mostly confined to hazel with a species-rich cover of lichens growing in old woodland or by streams. Like A. punctiformis (described elsewhere) the discs (perithecia) may be concentrated into tight patches but the one-septate spores lack the distinctive perispore typical of that species. North and west Ireland.

Key Identification Features:

• One-septate spores (19-26ųm long), slightly longer than A. punctiformis which also has a conspicuous halo around the spore (perispore)
• Strongly associated with hazel stands in species-rich woodlands and river valleys.
