Mr. Massee contributes tlie folio-wing remarks on some of tlie 

 rarer or more interesting species in the above list : — 



Agaricus ( Clitocyhe) Sadleri. — This very rare species, which has 

 only been collected two or three times previously, was first found 

 growing on a damp tub in the Glasgow Botanic Garden. It is 

 unknown outside Britain. 



Agaricus {Collyhia) tuherosa. — A peculiar little species, always 

 growing on the decayed pileus of some large agaric, more especially 

 on that of Russula nigricans. The mycelium forms a little 

 sclerotium. 



Agaricus {Collyhia) xanthopiis. — This is often confounded with 

 A. dryophilus, from which it differs in the broad gills being much 

 cut away behind. 



Agaricus {Psalliota) dermoxantlia. — A species only quite recently 

 recorded as British. It closely resembles A. arvensis, the "horse- 

 mushroom," but is distinguished among other features by becoming 

 primrose-yellow when cut or bruised. It is esculent. 



Lentinus cocldeatus. — A clustered, trumpet-shaped, tough fungus, 

 with a pleasant spicy smell resembling aniseed. Edible. 



Boletus luridus. — A large, showy fungus. The flesh is very pale 

 yellow, but instantly changes to a deep indigo-blue when cut or 

 bruised. Poisonous. 



Fomes annosus. — A parasitic fungus which is very destructive 

 to fir-trees. The base of the trunk is first attacked, and the 

 tree is eventually killed. This fungus is by some called Trametes 

 radiciperda. 



Poria sanguinolenta. — Forms a thin broadly-effused crust on 

 decaying timber. Pure white, but becoming stained blood-red 

 when bruised. Rare. 



Poria vaporaria. — Very common on decaying timber ; sometimes 

 becoming a true and destructive parasite.
