Taxa used in this study and their DNA sequences accessed in GenBank or publication.

aThe original species name in bold indicates that the material is subjected to DNA sequencing in this study; * and ◊ respectively represent dull and laccate species which have been accepted worldwide.
bThe basidiocarps from which DFP 4336 and DFP 3896 are derived were determined as G. chalceum by RL Steyaert [20]. Smith and Sivasithamparam redetermined these two associated isolates as G. cupreum based on the conspecificity between G. cupreum and G. chalceum[52] and the principle of nomenclatural priority [8].
c‘–’ indicates that the sequence is unavailable for this study. The sequence of DAR 73783 can be retrieved only from publication [20]. The framed sequence accession no indicates a pollution sequence.
