Cladonia macilenta or the lipstick cup lichen [2] is a species of cup lichen in the family Cladoniaceae. [3]
The species is red listed in Iceland as an endangered species (EN). [4] While it is found in various regions of the UK, it is considered potentially threatened in parts of the lowlands due to habitat loss. [5]
Verrucaster lichenicola, described by Friedrich Tobler in 1913, [6] was proposed to be a fungus with waxy pycnidia and hyaline conidia lacking septa. It was, however, a little-known taxon, as the type specimen was lost and not collected again. The rediscovery of the type material more than a century later revealed that what Tobler thought to be a lichenicolous fungus was instead pycnidia of Cladonia macilenta, and thus the two taxa are placed in synonymy.
