The cap is G-18 lines broad, the stem is 1-3 inches long, 2-4 

 lines thick. It is gregarious and appears from July to Sep- 

 tember. As an edible mushroom it is not as tender as some nor 

 as highly flavored, but it is satisfactory and enjoyable. 



It is related so closely to C a n t h a r e 1 1 u s u m b o n a t u s 

 that it has sometimes been regarded as a variety of it or has even 

 been confused with it, but the gills of that species are described 

 as straight, and in our plant they are constantly repeatedly 

 forked asinC. aurantiacus and C. a 1 b i d u s. The umbo 

 in our plant is small and pointed and often wholly wanting, but 

 in C. umbonatus it is represented as broad and blunt. Be- 

 cause of these discrepancies it seems best to keep our plant 



distinct.

PLANTS OF THE SUSQUEHANNA VALLEY AND 

 AD.JACENT HILLS OF TIOGA COUNTY 



BY FRANK E. FENNO 



The territory included in this flora consists of a strip of land 

 about 8 miles wide, lying on both sides of the Susquehanna river 

 and extending nearly east and west through the county. Its 

 surface is broken by the foothills of the Alleghany mountains. 

 These consist of a series of ridges from 1200 to 1500 feet above 

 tide. They are divided diagonally by the valley of the Susque- 

 hanna and separated laterally by the valleys of the Apalachin, 

 Wapasening, Owego, Catatonk, Pipe and Cayuta creeks. These 

 creeks have rapid currents. Their valleys are narrow in the 

 upper part, but expand toward the river into broad and level 

 fields. 



The Susquehanna winds its way through a tortuous valley 

 bordered on either side by banks, which generally slope grad- 

 ually to the broad and rolling hilltops. Yet the valley is defined 

 in some places by steep and rocky acclivities which rise from 

 300 to 400 feet above the surface of the river. These acclivi- 

 ties furnish congenial homes for many rock-loving species of 

 plants. The soil in the valleys is mainly alluvial, lying on a deep 

 drift consisting of sand, gravel and clay. This drift forms the 

 isoil of the adjacent hills. The territory contains very little
