Diederich, P. & Schultz, M. 2021. The identity of Verrucaster lichenicola Tobler. – Herzogia 34: 203–207.

The genus and species Verrucaster lichenicola, described by Tobler in 1913 for waxy pycnidia with hyaline, aseptate conidia on Cladonia bacillaris, was poorly known, as the type was missing and no additional similar specimen available. The recent discovery of the type in HBG allowed us to understand that it represents pycnidia of Cladonia, not of a lichenicolous fungus. The names thus become younger synonyms of Cladonia and C. macilenta.
