BURT—THELEPHORACEJE OF NORTH AMERICA. I 223 
Inerusting and ascending upward 1-3 сіп.; free branches 5-10 
mm. long, 1 mm. thick, sweep of fascicle about 5-10 mm. 
In moist places. New York to South Carolina, and west to 
Illinois. July and August. 
Тһе type is an incrusting specimen, covering as its main axis 
a small twig in one specimen and a moss in the other, and send- 
ing out а few lateral branches which are flattened towards the 
free ends and subfimbriate; main trunk is cylindric, latericius 
(of ‘Chromotaxia’), ends of branches paler; spores umbrinous 
under the microscope, tuberculate, 7-8 x би. Schweinitz de- 
scribed the species as becoming hard and cartilaginous, but 
this is an error probably due to the foreign matter surrounded 
by the main trunk. Several other specimens are present in 
his herbarium under various names.
