were growing on a rotten stump; but farther search failed 

 to detect others. 



Of our new Scottish species, the most regular in its recurrence 

 of those which have come under my own observation is Lentimis 

 scotiais. It was first discovered by the Rev. M. L. Anderson 

 in 1872, but remained undetermined till the following year, 

 when it was forwarded to the Rev. M. J. Berkeley. In the 

 locality in which I then found it I have gathered it regularly, 

 though never in abundance, every year since ; and during the 

 past autumn I got it in a new station, where it was growing on 

 fallen spruce fir branches. Previously it was found by Mr. 

 Anderson on decayed Ulex, and by myself always on birch. 



Of species recently added to the British Flora, some have 

 as yet been regular in their appearance, while others have been 

 noticed once, or, at most, twice. The observations of others 

 will doubtless confirm the experience afforded by such examples 

 as the following : — 



Since July 1873 I have found Ag. mcmumlarius regularly 

 every season in the same locality and at the same time. It 

 continues till October. I have never seen it except on the 

 same spot. 



For three years in succession, in September 1874 and 1875, 

 and in October 1876, I have found Cortinarius scbacciis in the 

 same place. 



Ag. maritimus., discovered in September 1874, has since 

 been recorded in various locaHties in Scodand. I have seen 

 it only twice. Dr. Buchanan White notes it as common in 

 Rannoch. 



In September, 1874, Leotia circinans was growing in abund- 

 ance in one locality. The most careful search has failed to 

 detect it since. Numerous specimens of Clavaria K?'onibholzii 

 appeared, during 1874 and 1875, in two stations not far apart; 

 and, in September 1875, I found a single specimen at Mon- 

 creiffe, which was exhibited at the Perth Fungus Show. It has 

 not appeared in the original stations during 1876. 



For two successive seasons, September 1874 and 1875, I 

 found numerous specimens of the rare Ag. caput-Mcdusa 

 in a small Scots-fir wood; but last year it had disappeared. 

 While referring to this plant, I may mention that in October 

 last I discovered Ag. scobinaccus, a species similar to, yet very 

 distinct from, Ag. ca'put-Medusce. Shortly afterwards I found, 

 in a different locality, a large cluster of a plant which I could
