Mycologia 



published by Overholts, the various original descriptions being 

 brief and inadequate. He finds the spores 3-4x2-3//, and the 

 cystidia 60-80 x 7.5-10 /x. Bresadola measured the spores as 

 4-4.5x2-2.5^. 



This species occurs on linden, poplar, oak, birch, beech, wil- 

 low, etc., in Europe ; and in this country on maple, oak, witch 

 hazel, alder, willow, linden, ironwood, and certain other decidu- 

 ous trees. I have found it very common on red maple. A speci- 

 men from Bresadola collected by Eichler on Pinus sylvestris 

 exactly agrees with ours on maple in gross characters, and Bresa- 

 dola finds the spores to be the same, but the cystidia less abundant. 

 Peck's variety subincarnata occurs on hemlock, but this is a dis- 

 tinct species.

Described as follows from specimens collected by Salle in 

 Santo Domingo and still preserved at Kew : 



" Totus resupinatus, centro crassiusculus margine tenuis sub- 

 liberatus supra sanguineo-tinctus ; poris minimis pallidis con- 

 textu lignicolori. Salle, no. 34. On dead wood. 



" Spreading for many inches over the decayed wood, 2 lines or 

 more thick in the centre, very thin at the extreme margin, where 

 the upper surface is separable, smooth, and stained with blood- 

 color. Pores scarcely visible to the naked eye, pallid, a line or 

 more long; dissepiments thin; substance wood-color."
