The lichenicolous genus Arthophacopsis Hafellner (Arthoniales) from India

Abstract

The new species Arthophacopsis zhurbenkoi is described here, which has been colonizing the thallus of Heterodermia dissecta. Additionally, Arthophacopsis heterodermiae, a species not previously recorded in India, colonizing the thallus of Heterodermia sp. and Polyblastidium dendriticum is reported for the first time from the country. Furthermore, we include a comprehensive key to identify all known lichenicolous species that colonize lichen genus Heterodermia in India.
