New combinations and synonyms inGraphidaceae(lichenized Ascomycota) from India

“…Recently, Swarnlatha (2017) described G. andamanica from the Andaman Islands. The author mentioned cinnamon red granules in the hymenium but this is not a constant character.…”

Phylogenetic placement and reappraisal of Diorygma karnatakense including the new synonym, Diorygma dandeliense, from Maharashtra, India

“…The most common secondary compounds include norstictic, stictic and/or protocetraric acid (Kalb et al 2004;Feuerstein et al 2014). The genus is mainly tropical to subtropical in distribution (Staiger 2002;Kalb et al 2004), and c. 42 species have been reported from India (Kalb et al 2004;Archer 2006Archer , 2007Cáceres 2007;Archer & Elix 2008;Makhija et al 2009;Sharma & Makhija 2009a, b;Tripp et al 2010;Sharma & Khadilkar 2012;Mohabe et al 2015;Rashmi & Rajkumar 2015;Sinha et al 2018;Nayaka et al 2019;Behera & Nayaka 2020;Gupta et al 2020;Behera et al 2021;Swarnalatha 2021). A recent revision of the family Graphidaceae (Rivas Plata et al 2013) also showed that the genera Diorygma and Thalloloma are not mutually monophyletic, and this genus complex requires further study.…”
