Chateri, but differs in the spores being larger, and the hairs 

 thicker. It may be a variety of this very variable species, 

 or, the shape of the spores and hairs may indicate a different 

 species.' Boudier places H. Chateri in his genus Melastiza. 

 Dr. Rehm, in ' Rabh. Kryt. Flo. (Disc.) p. 1059, places it under 

 Lachnea. According to our idea it comes between Lachnea 

 and Humaria. Rehm gives the spores of Chateri ' 1-2 guttulate, 

 coarsely warted, 15-20 X 9-10 ' ; asci 200-250 x 12-14 ; ours 

 are 280-320 x 12-14 ^a. Saccardo refers to German and Italian 

 forms with spores 16-17 X 7-8 /x. 



Although doubtful, all points considered, perhaps it will 

 be best to leave it with Chateri at present. The Hull specimens 

 have been carefully figured and described.

As will be seen above, this variety has been considered by 

 several mycologists to be a distinct species. In my opinion, 

 Massee (' Brit. Fung. Flo.', IV., pp. 488-9) is quite right in plac- 

 ing it under G. guernisaci as a variety. Characters confined 

 solely to the paraphyses, such as their more or less profuseness, 

 presence or absence of a slight brown tinge at their apices, or 

 their varying from simple or occasionally forked to repeatedly 

 forked towards their tips, scarcely justify the raising of a 

 variety to a species.

In Knowledge for May, Mr. W. G. Clarke writes on ' Striae on Neolithic 

 Flint Implements.' In this he points out that humanly worked surfaces 

 of the flints are scratched and ' our geological knowledge affords us no other 

 possible course of these striae than glacial action.' This means that 

 neolithic man must have existed during or before the Ice Age. We don't 

 believe it !
