Joshi, Y.
The present paper interprets a new species and a new record of the lichenicolous fungus Pyrenidium from India. The new species P. dimelaenae Y. Joshi was found on the thallus of saxicolous lichen species Dimelaena oreina (Ach.) Norman and is characterised by globose to subglobose black perithecia with light greenish blue tint in ostiolar channel. The new species shares many morphological characters with other Pyrenidium species but differs in its number of spores and hosts. In addition, two new records, i.e. Lichenostigma dimelaenae Calat. et Hafellner and P. borbonicum Huanraluek, Ertz et K. D. Hyde are also being reported from India for the first time.
