192 The Scottish Naturalist. 



Coming down to more recent times, the late Mr. Jerdon 

 deserves mention, as quietly and in a manner void of assump- 

 tion adding to the number of Scottish Cryptogamia. 



The rarer Scottish Fungi found by each and all of these 

 gentlemen should be sought after again by their successors, so 

 as to establish their work. 



Of Greville's species his Hysterium figured as Hysterium 

 varium, but which Berkeley has named H Carmichalianum, 

 although figured by Greville was found by Carmichael, and the 

 specimen in the Edinburgh Herbarium, which I examined by 

 permission of Professor Balfour, contains sporidia very similar 

 to those of Hysterium repandum, Blox., except in being rather 

 larger. It may be that additional specimens if found would 

 prove that the two are identical. 



ALcidium ParnassicB found by Greville in the neighbourhood 

 of Edinburgh, I am informed has since been found by a mem- 

 ber of this Society ; until recently the only specimen I had 

 seen was the single leaf from Dr. Greville in the Edinburgh 

 Herbarium. 



Puccinia Chrysosplenii, which, by the way, is quite different 

 rom the P. Chrysosplenii of German authors, has recently been 

 found south of the Tweed by my good friend the Rev. J. E. 

 Vize, of Forden, fully according with Greville's specimens. 



Helotium ochraceum, the Peziza ochracca of Greville ; Helo- 

 tium cribrostwi, the Ptziza cribrosa of Greville ; Helotium claro- 

 flavum, the Peziza claroflava of Greville, are all species so rare 

 that they merit a good search. 



Cylindrosporum concentricum^ Grev. fpl. 27J, is a species 

 which has given rise to some confusion, and one I have never 

 seen. It occurs on cabbage leaves, but I am not aware that it 

 has been found since Greville's time. ' 



Puccinia Fabce, according to Greville's figure, is only an 

 Uromyces ; but he speaks of it as containing more than one 

 cell. I have never seen other than Uromyces on leaves of the 

 bean, although included in the Handbook, on the faith of 

 Greville and Berkeley. A Puccinia on Faba is therefore a 

 desideratum. 



Sphoiria ( CryptospJuvria ) Tamariscinis, Grev., is a species 

 which should be sought, as I do not think that the Sp/uuria 

 on Tamarisk, with which I am acquainted, is the same species. 



Nectria Purtoni ( Cucurbitaria pinastri of the S. C. Flora, pi. 

 50), is certainly rare, and should be diligently sought after.
