LACHNOBOLUS, Fries. 



Sporangia sessile, (or very short-stalked), gregarious or 

 closely packed together. Peridium wall exceedingly delicate, 

 smooth, opening irregularly. Capillitium forming a loose net 

 attached by numerous branches on all sides to the peridial 

 wall. Spore-mass with capillitium delicate rose or flesh- 

 colored, or yellow. 



1 8. Lachnobolus incarnatus, Albertini and Schweinitz. 

 Plate II, Figs. 2, ^a and 2h. 



Sporangia spherical or ellipsoidal, about .005 broad, rarely 

 distinct, usually closely agregated. Peridium membranous, 

 fragile, flesh-colored, shining. Capillitium of manifold branch- 

 ing threads united to form a loose net, the threads character- 

 ized by numerous expansions or nodes .010-.018 broad, and 

 everywhere finely punctate. Spore-mass bright flesh-tinted; 

 spores .0075-.009, smooth. 



The specimens referred to this species are so placed from 

 description only, the author having no authenticated speci- 

 mens for comparison. Of the correctness of the determina- 

 tion there seems, however, no reasonable doubt. The capilli- 

 tium is absolutely characteristic. The only points in which 

 our material departs from the description given by Schroeter, 

 are the somewhat greater (average) diameter of the spores 

 and capillitium nodes. 



LYCOGALA, Micheli. 



^thalia rounded, more or less nearly spherical, single, gre- 

 garious, or crowded, coalescent. Peridial wall double, the 

 outer membrane, thick, papery, not smooth; the inner more 

 delicate, affording support to the richly developed, very irreg- 

 ularly expanded, branching and reticulated capillitium.
