Taking the Agaricineae as a whole, the most interesting genus is 
certainly Aygrophorus, of which twenty-four species are recorded. 
After examining all the Guernsey forms, Mr. George Massee favoured 
me with the following suggestive note :-— 
‘The occurrence of so many species of Hygrophorus within so 
limited an area is very remarkable, and careful study would almost 
certainly add to the number already observed, as several specimens 
received in a condition too imperfect for certain identification did 
not appear to belong to recorded species. Furthermore, the remark- 
able variation in form, colour, and size of such species as H. puniceus, 
A. coccineus, and others, suggests a line of work which could not fail, 
if thoroughly investigated, to aid to a very material extent in solving 
the interesting problem bearing on the causes of variation in species. 
The examples from Lancresse Common proved exceedingly in- 
teresting from this standpoint. Perfectly typical specimens occurred 
mixed with such varied departures from the type that the extreme 
forms, if collected in localities apart from the typical form, and not 
connected by intermediate links, might reasonably have been con- 
sidered as distinct species. Why is this? The question can only 
be answered by some person resident in the island ; and the fascina- 
tion certain to accrue from a study of this cause of variation, and the 
great benefit to science generally, should stimulate some one to 
undertake the task.’ 
Three fungi new to science were discovered in Guernsey — 
Cutopilus sarnicus, Omphalia Luffit, and Verticllium Marquandit ; 
and ten species were added to the British Flora, viz. Lepiota 
carneifolta, Marasmius globularis, Agaricus rubellus, FPolystictus 
tomentosus, Lachnea pulcherrima, Bertia collapsa, Torula asperula, 
Volutella vitis, Fusarium argillaceum, and Phyllosticta hedericola. 
Besides these, there are several excessively rare British species in
