The above reports and collections show that Lenzites sepiaria may 

 attack the wood of the species of Abies, Alnus, Jimiperiis, Larix, 

 Picea, Pinus, Popiilus, Pseudotsuga, and Tsuga. It may be expected 

 to occur occasionally on the w^ood of Chamaecyparis, Cupressus, 

 Libocedrus, Secpioia, Thuja, and Taxodium. Wliether it may also 

 attack the wood of deciduous species other than those belongmg to 

 the genera Alnus, Popuhis, and Salix is uncertain; specimens of 

 fungi, which are so poorly developed' that it is impossible to identify 

 them with certainty, have been collected upon a number of the 

 deciduous species. 



This fungus is rather rarely found on the wood of living trees 

 (Ilahn, lOOS, Ilcnnings, 190.3a, 19()3b, Von Schrenk || No. 105, 

 Spauldhxg II No. 2266), and so far as the writer knows has never been
