A few additional records, derived from other sources, are 

 now added, as well as others based on information obtained 

 at excursions of our own Society, or due to observations made 

 by the compiler himself, in the course of brief visits to local- 

 ities within the Forth Area. 



Species not recorded for the Forth Area in the ' Mycologia 

 Scotica ' or its Supplements, or in Professor Trail's two re-
