" Most distinguished and estimable sir ! 



"I havs received with peculiar pleaaure the 'Clavia Agaricinorum, 

 and for the gift I present my most sincere thanks. I was especially pleased 

 with the list, so greatly enriched, of species found iu Britain, for the oppor- 

 unity it afforded me of comparing them with those of Sweden. I have not a 

 doubt that there are more species still remaining to be discovered in Britain, par- 

 ticularly in the pine woods of Scotland : and many very handsome species pecu- 

 liar to our own fir foreats, for inatance, Lactarius scrobkularis and the larger 

 Cortinarii appear to be wanting in Britain. 



" Several Bpecies, moreover, have been omitted by my friend Berkeley, 

 which certainly belong to the Britiah Flora ; for inatance, Ag. clavipcs (to which 

 without doubt belong Ag. mollis of Bolton) Ag. compressus of Sowerby, alto- 

 gether distinct from Ag. butyraceus and Hygrophorus ovinus, but closely resem- 

 bling Ag. metachrous. 



" I may perhaps be allowed now to make some remarks on plate 6 of the 

 book. 



"The space in the series Leucospori loft vacant between 2 arid 3, ana- 

 ogous to Pluteus and Pilosace, is very well filled by the subgenua Hiatula, de- 

 scribed in my work, ' Nov. Sym. Myc.' Of this genus there are numerous tropi- 

 oal species and two are found growing in our hot-houses, on the stems of orchids. 

 They have been found growing in a similar situation at Amsterdam. 



" We muat exclude the reaupinate species from the Pleuroti No. 6. 



" Ag. xanthogrammus is chiefly remarkable from the fact that I know 

 of no other species with a partial veil amongst the Hyperhodii. I am unable 

 to refer Ag. echinatus to the Hyperhodii inasmuch as the spores are not rosy- 

 coloured, but subfuscous, like those of Ag. cretaceusaniAg. campestris. Ag.hamato- 

 spermus also has ita spores subfuscous, and not rose-ooloured. I have gathered 

 this species lately in Sweden, and I suspect that Ag. montanum, var. cervarium,
