On time or fashionably late for lichen discoveries in Singapore? Seven new species and nineteen new records of Graphidaceae from the Bukit Timah Nature Reserve, a highly urbanized tropical environment in South-East Asia
Based on collections focusing on Graphidaceae made in 2012 at Bukit Timah Nature Reserve (BTNR) in Singapore, seven new species are described: Astrochapsa sipmanii, differing from A. astroidea in the olive-brown thallus and thick and coarse apothecial pruina; Fissurina duplomarginata, differing from F. insidiosa by the double margin of the lirellae and the more greenish, rough thallus; Graphis bukittimaensis, differing from G. phaeospora in the erumpent lirellae with lateral thalline margin and the consistently 1-spored asci; G. singaporensis, differing from G. novopalmicola in the much smaller ascospores and in the immersed, densely branched lirellae with thin lateral thalline margin; Ocellularia subudupiensis, differing from O. udupiensis in the presence of three unknown secondary substances and in the comparatively rough thallus surface; O. gueidaniana, characterized by small, transversely septate, hyaline ascospores, prominent, carbonized but ecolumellate apothecia, and two unknown chemical substances resembling metabolites in the stictic acid chemosyndrome; and O. rivasplatana, differing from O. exigua in the larger, broad-pored apothecia with black-rimmed margin and filled with a black-topped columella. Nineteen species are recognized as new records for Singapore. The substantial diversity of Graphidaceae in this reserve suggests that many more taxa are awaiting discovery, even in such a highly urbanized location.
