The Scottish Naturalist. 193 



Puccinia variabilis, according to Greville, has the cells often 

 subdivided and constricted. I must confess that I could never 

 find a spore with more than one septum in what is supposed to 

 be Puce, variabilis, and the experience of others coincide with 

 my own. If specimens could be found in Scotland upon Dan- 

 delion leaves, agreeing with this portion of Greville's descrip- 

 tion, the fact should be recorded. 



Whether Greville's Peziza reticulata (pi. 156) be the same as 

 P. venosa is considered by some to be doubtful. The Scotch 

 plant was found near Edinburgh, and it would be well that the 

 forms of P. ve/iosa found in Scotland in the spring should be 

 carefully compared with southern forms. 



Lophium elatum (pi. 177), is another of Carmichael's plants 

 first figured by Greville. It appears to be everywhere rare — 

 though since found on the continent of Europe — and is always 

 worth searching after. 



Dothidea betulina is probably not very uncommon in Scot- 

 land ; indeed Greville states that it is common, whereas I have 

 never met with it in England or Wales. 



Sticlis Wauchii ( Crypto my ces Wauchii, Grev.J is clearly a 

 condition of Rhytisma maximum, which occurs in some parts 

 of England. 



Choetopsis Wauchii (Grev. fig. 236) I have never seen in any 

 condition, or from any part of the world. It is a very curious 

 mould, and requires further examination. It was found in 

 spring, on rotten wood, at Fox Hall, and might probably be 

 found again if sought after. 



Virgaria nigra is another scarce mould on dead trunks, found 

 at Appin, but which is also found in N. Europe. It is one of 

 those obscure plants which, being seldom met with, has never 

 been satisfactorily figured. 



These are some of the fungi figured or described by Greville, 

 which it is well that Scottish Cyptogamists should bear in 

 mind, and probably they will be found again under similar 

 conditions. For my own part, I always feel more satisfied in 

 finding a lost plant which has been described by a botanist of a 

 previous generation than in two or three which are absolutely new. 



There are also records of other rare plants in Scotland, be- 

 sides those figured by Greville, which may be found again. 

 For instance, a pale rosy-pink Peziza on old Stcreum, which I 

 named Peziza stereicola, and of which the only specimen is in 

 the Edinburgh Herbarium. A pretty little red Peziza on fir
