larger Fungi. They are much more variable — the rarer species 

 at least — in their recurrence. In confirmation of this, I may 

 quote the opinion of the Rev. M. J. Berkeley, regarding 

 Agariciis storea : — " It is considered very rare by Fries ; but it 

 is probably one of those species which are abundant in some 

 one year, and are not found again for a generation." * 



Regarding A^::;. storea, I may mention that Mr Worthington 

 Smith, who exhibited it at South Kensington in 1873, identified 

 it at the Perth Fungus Show in 1875. The same plant had 

 been found previously by the Rev. J. Keith, who has drawn my 

 attention to the following facts : — The plant which Mr Worth- 

 ington Smith identified at Perth, as Ag. storea, was fasciculate ; 

 while Fries, both in his " Monographia," and " Epicrisis," de- 

 scribes it as ^^ solitarius.^^ In the last edition of his " Epicrisis,'' 

 however, the expression " solitarius " is omitted. Otherwise, the 

 description in •' Hymenomycetes Europa^i" is verbatim that of 

 the first edition, t 



Ag. carhonarius was gathered in Morayshire, by the Rev. J. 

 Keith, in October, 1870, and again in October, 187 1. He has 

 not, however, noticed it since. It occurred on a spot in a fir 

 wood, recently cut down, where a quantity of brushwood had 

 been burned. Ag. clavipes has been recorded in various 

 localities in the north-east of Scotland. My first acquaintance 

 with it was in 1875, in company with Mr. Worthington Smith, 

 who gathered it at Moncreifi'e ; and during 1876 I found it 

 twice in different counties. Dr. Buchanan White informs 

 me that it occurs in the neighbourhood of Perth, and in 

 Rannoch. 



Ag. euchrous was found during one of the late excursions of 

 the Woolhope Club. Of this Mr. Worthington Smith says — 

 " It is a curious fact, that for three years in succession a single 

 plant of this handsome species has been found at Dinmore, 

 each year in a different stump. Though rotten stumps abound 

 at Dinmore, no amount of searching ever leads to the discovery 

 of a second specimen of A. euchrousTX I was fortunate in 

 gathering this beautiful species at the same time, along with 

 Dr. Buchanan White, during one of the excursions of the 

 Cryptogamic Society at Killin. Three specimens attached
