' During the reading of the last proof-sheets I have got to sight: Du Rietz Lieh. Fragm. 

 HI: De svenska Xanthoria-arterna. Svensk Bot. Tidsskr. 1921 p. 181 — 191. Du Rietz

 Ivchnca has been mentioned so frequently in the previous text of my paper that it was 

 impossible now to use his name Xanthoria candelaria (Acii.l Ar>'.
