NEW OR NOTEWORTHY FUNGI 191 



slender spores. Cytos^ora foliicola Lib., which may occur on the 

 very same leaves, is distinguished from the smaller conceptacles 

 not only by its (pallid) disc, but also by its smaller curved (sausage- 

 shaped) spores. Its var. Kalmice, Sacc, however, is not very 

 different from C. Eitonijmi, and should be placed as a variety of 

 the latter. 



229. Ceuthospora Laurocerasi comb. nov. CeutJiospora 

 Lauri Grev. Scot. Or. Flor, pi. 25i (1827). Sacc. Syll. iii, 279. 



Cytospora Laurocerasi Fckl. Bnum. Fung. Nass. no. 437 (1860). 

 Sacc. Syll. iii, 276. 



On dead leaves of Primus Laurocerasus. Common everywhere. 

 Var. ramulicola Vize, Fung. Brit. no. 104, on dead shoots of the 

 foregoing summer, = Cytospora Laurocerasi var. ramulorum Sacc, 

 is equally common. 



It is necessary, in consequence of the widespread impression, 

 bred of Greville's mistake and Saccardo's statement in Syll. iii, 

 279, that Greville's Ceutliospora Lauri grew on Laurus nohilis, to 

 point out that in Britain " the Common Laurel" meant (and still 

 means) P. Laurocerasus. So far as I know, no Ceutliospora on 

 Laurus has ever been found in Britain, certainly not by Greville, 

 as his figure clearly shows in spite of his words. The genetic con- 

 nection of the two above-mentioned forms, heretofore placed in 

 distinct genera, becomes obvious when a comparison is made with 

 C. Euonymi (no. 228), quite apart from the fact that little distinction 

 exists between the two except in mere size, and that in this respect 

 it is quite easy to obtain a complete gradual series between the 

 small and the large conceptacles. In such a case it is clearly 

 justifiable to choose the more accurate specific name, and drop the 

 prior misleading one, for a false name, given in error, should not 

 be allowed to carry any rights of priority. The hard dense 

 stromata of the large conceptacles probably act as resting stages, 

 being more or less of a sclerotioid nature, in both this species and 

 C. Euonymi.
