Herpotrichia nigra Hartig. 1 This parasite is distin-ui.-hed 

 by its grey mycelium, which covers and completely envelops 

 twi^s and young plants. On the dwarf mountain pint- it is 

 not uncommon to find branches bearing patches of Macki-m-d 

 needles closely bound together by gossamer threads, the other 

 parts remaining still green and forming a background against 

 which the blackened masses show up prominently (Fig. SO). 

 Young spruce plants under a metre in height and the lower 

 branches of taller trees are frequently completely enveloped in 

 mycelium, and, where they have been pressed down to the 

 ground by weight of snow, the twigs may be woven round 

 and fastened to the earth by a felt of mycelium.
