APPENDIX. 



I shall add here certain si^ecies which, though not 

 strictly belonging to Perinporiaceae, inasmuch as the 

 perithecia in them are provided with an opening 

 for the escape of the sporidia, yet are so nearly 

 related in other respects that they were included in 

 the family in the Mycologia Scotica, following the 

 a,rrangement in Cookes Handboolc. 



Genus Microtliyriuni Desm. 



M. microscopicum Desm. (M.S. 1849). — On dying 

 or dead leaves of Bu.vus sempervirens ! and of other 

 shrubs and trees. A form occurs near Aberdeen on 

 dead leaves of Quercus Rohur (oak) I which has 

 received the name of M. Quercus Fuckel ; but which 

 does not differ in any essential respect from M. 

 Tnicroscopiciim.
