Mycologia 



convex, emarginate, periphery fimbrio-ciliate, concolorous to dark 

 brown. Spores 5-8 X ZS^- 

 Substrata : On trees. 



Geographical distribution : Confined apparently to the 

 Boreal zone of the western coast states from California to British 

 Columbia, east to western Montana. The San Diego record seems 

 very doubtful from the point of view of locality. 



Observations : This alpine species, described by Nylander after 

 Tuckerman's death, though restricted in its range, is one of the 

 most unique and easily determined species. It is commonly fer- 

 tile, and its ciliate apothecia distinguish it at once from all other 

 species of our area.

Note : Stizenberger* described in the Proceedings of the Cali- 

 fornia Academy (5: (2), 537-538. 1895) a new caespitose Alec- 

 toria from Guadalupe Island off the coast of Lower California. 

 The type or topotype is now in the National herbarium with a 

 postal card from Stizenberger to Henry Willey from whom he 

 received the plant dated August 24, 1893. I n view of the fact 

 that only scanty, sterile material is available I prefer to give here 

 only Stizenberger's account:
