NOTES<br />
Much of the information for this genus comes from my unpulished thesis (1975). To avoid possible<br />
confusion I have tried to account for all of the names included in it. The synonymy from the thesis and that<br />
accumulated in the 20 years since is also given.<br />

The material in the Acharian herbarium under Verrucaria analepta contains three pieces of bark labelled<br />
"Suecia" (marked A, B, C) and therefore candidates for the lectotype. Pieces A and C lack ascospores but the<br />
hamathecium is of the "Naetrocymbe-type". Piece C also has microconidia in accord with Naetrocymbe.<br />
Piece B has hamathecium, asci, ascospores and microconidia identical to those of the species currently<br />
known as Arthopyrenia lapponina. I have selected Piece B as the lectotype as it contains good material of<br />
both teleomorph and anamorph and to stabilize the usage of Arthopyrenia in the broadest possible sense (see<br />
