Very common, a pernicious parasite on the stems and branches of 

 Larix decidua. Rostrup found it in all parts of the country and often 

 recorded its distribution and biology; he supposes that it was the 

 attack of this fungus which destroyed all larger plantations of Larix 

 in Denmark during the years 1840—50 (R 79 b ^'). Rostrup first noti- 

 ced it near Viborg in 1874. Rostrup (83 d °^°) states a particularly 

 severe attack on three - or - four - years - old Larix near Glorup on 

 which occasion he noticed that a conidial stage of this fungus was 

 like whitish warts, producing curved spermatia. The attack seemed to 

 be dependent on meteorological circumstances (frost etc.); in planta- 

 tions on the dunes of the North-Sea, this fungus completely prevents 

 the cultivation of Larix (R 83 d) ; at Tisvilde its attacks are also very 

 considerable (H. M. 90 "=) especially in cold hollows (R 79 b). 



Besides on Larix decidua it has a few times been noticed on Larix sibirica.

Rehm rejects the old, well-known name of calycina judging it to 

 be a common name of several species which has often been used for 

 other species than the present one; the latter supposition is, no doubt, 

 quite correct, but according to my opinion it is not incontrovertible.
