NOTES

Dennis (1957) separated K. coenopus from K. clavus by the fertile parts of the former being "somewhat larger and more flat-topped..., packed tightly together in dense swarms on bark, with shorter, often simple stalks, more numerous perithecia and even less prominent ostiolar papillae." Nonetheless, he mentioned that the separation of these two taxa is not clear cut and intermediate states are not uncommon. Dennis (1961) later synonymized K. coenopus with K. clavus. Like Dennis (1961), we have not been able to unequivocally separate K. coenopus from K. clavus, and thus consider them as synonyms at present.

Type material of Kretzschmaria novoguineensis has certain features of K. cetrarioides: coarsely papillate ostiolar openings and slightly less than spore-length ascospore germ slit. However, its subsessile stromata lead us to place it here.
