150 Microfungi at Traquair and Roslin. [Sess. 



which could be satisfactorily determined. The information 

 thus obtained is embodied in the following list of 70 species. 



Owing to the minute size and inconspicuous appearance of 

 many of these plants, they can only be discovered after a 

 careful search, which involves much more time than is usually 

 available at such excursions. It will be observed from the 

 list, however, that several interesting species were noticed on 

 both occasions ; and this may be regarded as some indication 

 of the richness of the localities visited, where the prevailing 

 conditions appeared very favourable to the development of the 

 lower forms of plant life. Much greater success might there- 

 fore be expected from a careful search made under more 

 satisfactory circumstances. The most notable species obtained 

 was Marssonia daphnes Sacc, found in the garden at Traquair 

 House, and not previously recorded for Britain. For its 

 identification I am indebted to Miss A. Lorrain Smith, F.L.S., 

 South Kensington, who has already referred to the discovery 

 and published a description of the species.'^ 



For convenience in printing, the species found at Traquair 

 are denoted by the figure " 1," and those at Eoslin by the 

 figure " 2," appended to description of habitat.
