78 THE LARCH CANKER 



calls the fungus DasyscypM calycina (Schum.), and gives the 

 dimensions of the spores as 20X8 ij.. This, with the habitat 

 of the fungus ' an diirren berindeten Aesten von Larix 

 europaea nicht selten im Herbst ', leaves no doubt that he 

 was describing the canker fungus. 



It is on tliis description that the name DasyscijpJm 

 calycina must be founded, since it is the first about which 

 no doubt can be entertained. Fuckel does not mention 

 any other species of Dasyscyplm which grows on conifers. 



Subsequent authors may be quoted in the usual way.
