Lichens. 

 (By A. Lorrain Smith.) 



New Lichens.* — A. Zahlbruckner describes a number of new species, 

 with various added notes. Arthopyrenia peranomala he classifies among 

 lichens without being able to detect gonidia, from the fact that the 

 perithecium is open below, a character not to be found in allied fungi. 

 A new Usnea from India {U. subchalybsea) forms dense erect clumps 

 about 4 cm. high. It approaches U. sulphured in habit. Finally, two 

 new species of Buellia, on basalt rocks from Arizona, differing from each 

 other in the reaction with potash and other details. 



Lichens from Greece. — The list of 178 lichens here published repre- 

 sents a collection made by Rene Mairef during a botanical journey in 

 l'.)04, and by him, along with M. Petitmengin, in 1906. They were 

 examined and determined by Harmand and Bouly de Lesdain. The 

 flora of the calcareous hills resembles that of the calcareous Alps ; that 

 of the siliceous rocks has not been sufficiently explored to permit of wide 

 generalisation. A striking feature of the flora is the predominance of 

 Lecanorine forms over Lecideine ; there are only few Arctic-Alpine 

 species on the high summits, but on these heights were found lichens 

 that inhabit the hills and lower mountains of Central Europe. Corti- 

 colous species are much like those of Central Europe. A few new 

 species and sub-species occur in the list. 



Arctic Lichens.} — Otto Y. Darbishire includes in this list the 

 lichens recorded from Arctic America, Greenland, Spitzbergen, and
