Abstract

A survey of the lichen genus Pseudopyrenula in India is presented, with morphotaxonomic accounts of all six accepted species. Two species, P. himalayana and P. megaspora, are new to science. Both species resemble P. staphyleae but have a lichenized thallus and eccentric ostiole. Furthermore, P. himalayana differs from P. staphyleae in having immersed perithecia and narrower ascospores, while P. megaspora differs in the larger ascospores. Detailed descriptions of the new species are presented, together with notes on their chemistry, distribution, ecology and taxonomy. A key to all known species of Pseudopyrenula from India is also presented.
