The same distribution in S. E. Norway as our warmtli-loving deciduous 

 trees. Most common near the coast. 



On the stems of Fraxiiiits, Pop ti /its, and So7-biis in the lowlands. In 

 inland provinces Fraxii/iis rapidly becomes rare, and at greater elevations 

 Populiis has an almost naked, lichen-free stem, in the lowlands there is 

 hardly one tree so rich in lichens as Populus. R. popiiliiia has never been 

 recorded higher than 400 m. s. m. in Norway. — Rare in Western Nor- 

 way; a very isolated specimen recorded from Saiten, but the Trondhjem 

 and Helgeland districts have been poorlv investigated. 



A slight pressure on the glass will being the spores in rotation. Each 

 apothecium contains straight as well as curved spores; I have never investi- 

 gated a plant of the/>o/)//////r?-habitus which did not contain some curved spores.
