Natural Order Agaricaceae. 



Although L/efroy quotes Agaricus campestris (edible mush- 

 room) as having been found near Pembroke churchyard, yet 

 I have failed to hear of anyone finding such a growth on the 

 islands. Mushrooms are grown under cover in a few gardens 

 from imported spawn only, and there is no instance that I can 

 trace of their natural growth. 



Natural Order, Bryaceae. 



Tortula Muralis, A small moss forming a green, velvet-like 

 mantle on old walls, rocks and wayside banks. Is common. 

 Its thread-like stems, minute, terminate in small caps contain-
