38 ANNALS OF SCOTTISH NATURAL HISTORY 



1 80 jj, by 6 jj,. In the " Icones Fungorum" of A. N. Berlese 

 Britain is not cited as one of the countries in which L. Caprece 

 occurs ; but it is stated to be widely distributed in Europe. 

 EPICYMATIA THALLOPHILA (Cke.} Sacc., (Sphceria thal/ophila, 

 Cooke). 88, on Lecanora subfitsca, on alders on the south 

 side of Loch Rannoch. 



Dr. M. C. Cooke states 1 that the original specimens on 

 which this species was founded were collected by Dr. L. Lind- 

 say in Glenshee, August 1856, and adds the following remarks 

 upon it : " It is not improbable that this is a naked Sphceria 

 springing from the wood beneath, and perforating the thin 

 lichen thallus. A single small specimen is all we have seen, 

 and that was insufficient to satisfy us on this point." This is 

 evidently not the case, as we have found the perithecia 

 occurring both on the thallus and on the apothecia of the 

 lichen ; and from one to fourteen perithecia have been ob- 

 served on a single apothecium of the Loch Rannoch 

 specimens.

OMITTING for the time any mention of Cerastiuw 

 cerastioides, to use the name imposed on us by the Vienna 

 Rules, I propose to bring before British Botanists some
