Named in honour of the ecologist Francis Rose who tutored the likes of David Bellamy, this is a crustose species of old basic-barked trees where it grows best on the mossy boles of mature oaks. The green-brown thallus produces clusters of isidia like cauliflower heads in miniature, but coloured ochre. This configuration is entirely distinctive. Discs are unknown in Ireland; southern.

Key characteristics

  • Thallus green-brown, producing a scaffolding of clustered, ochre-coloured isidia like cauliflower heads
