Solenia 



THELEPHORACEyE 



427 



XC. SOLENIA Hoffm. 

 (From the short pipe-like shape ; Gr. solcn, a pipe.) 



Cylindrical, more or less contracted at the mouth, the external 

 hairs in some species rough with particles of oxalate of lime, cavity 

 covered with the hymenium. Basidia tetras- 

 porous. (Fig. 105.) 



The species are all minute, rarely exceeding 

 T V in. in height. They grow, usually in crowded 

 masses, on rotten wood. They are closely 

 allied to Cyphdla, but are distinguished by the 

 densely crowded habit and by the cylinders 

 never expanding. 



Fries has placed this genus in the Poly- 

 poracece, but each cylinder in Solenia is a distinct 

 Peziza-like plant and not comparable with a 

 mere tube of one of the Polyporacece. To be 

 allied to the Polyporaeea each cylinder should 

 be lined with minute basidia-bearing tubes. 



Externally white. 

 Externally ochreous.
