rills were gay with the pink-flowered Sedum villosum. In several 

 places we saw a Cerastium allied to C. alpinum, but evidently 

 distinct^ and as clearly distinct from C. latifolium. 



Respecting this plant I hope to send a more minute account 

 at a friture time^ believing it to be an undescribed species. 



Hieracium cJwysanthum occurs sparingly on some parts of tlie 

 Ben Lawers range^ and we found a single plant of the ovongQ- 

 flowered _/Sfi!^rifiji2'oi^e«,- ya,r. autumnalis. In Glen Lochay we 

 noticed Carex Persoon'.i and Bartsia alpina, in addition to other 

 plants noticed before. In Grlen Dochart we saw Hiei^acium holo- 

 sericeum, and once met with Azalea procumbens. A small loch at 

 the foot of Ben Mohr produced Nuphar minima and Sparganium 

 natans..

CHAPTER IV. 



I shall naw proceed to give the. names and descriptions of 

 some of the common species of Fungi which are found in this 

 country, in order to illustrate the various suborders into which, 

 as we have seen, they are divided. 



1. AGABICINL 



Beginning with the higher Fungi, we have first the suborder 

 Agaricini, in which the hymenium or fructifying surface consists 

 of lamellfe, or gills. The plants of this division are familiar to 

 almost every one by the names of Mushrooms, Toadstools, etc., 

 and may be considered as the vulgar type of the whole class of 

 Fungi. The number of species is very great, nearly four hun- 

 dred having been found in this country alone, and they occur 

 almost everywhere, chiefly in autumn. 



The principal genus of the suborder is the large and extensive 

 one of Agaricus, of which the following generic character is given 

 in Hooker's ' English Flora ' (which I shall take as my text-book, 

 being the latest systematic work on British Fungi).
