The basidiolichens in India are rare and prior to this study, only three species were known. A detailed study of basidiolichen
specimens freshly collected and some already available at herbarium LWG resulted in interesting species of Sulzbacheromyces.
Notably, all these specimens were collected from northeastern states of India. Sulzbacheromyces arunachalensis is described
as new to science which is characterized by its terricolous and crustose thallus; chlorococcoidal photobiont; terete to fusiform,
unbranched, white to off-white basidiomata; reniform, 7.1–8.9 × 3.0–3.9 µm basidiospores. The novelty of the species is
further confirmed by phylogenetic analysis of the nrITS sequence. In addition, S. bicolor and S. yunnanensis are reported for
the first time in India. A key to all known species of Sulzbacheromyces from the world is provided. The discovery of the new
species from northeastern India once again proves it to be a lichen diversity hotspot. The present communication emphasises
the need for special focus on basidiolichen study in India.
Key words: Arunachal Pradesh, biodiversity, Himalaya, lichenized fungi, molecular systematics, nrITS.
