STEMONITIS. 213 



I/, epidendrum. 



Subglobose, pinkish, then brown ; spores pale violet. 



This is one of the most common Myxogaster to be found in the Lehigh 

 Valley. It is easily identified by its appearing like so many small puff- 

 balls on decayed logs. 



Genus VIII. I^ACHNOBOIyUS. 



Sporangia globular, simple, without a columella, capilli- 

 tium present, grown to the walls of the sporangium. 



There is only one species belonging to this genus, as follows: 



I/, globatus. 



The characters are the same as the generic characters. They 

 grow only on last year's chestnut burrs. The spines are liter- 

 ally covered with them, like so many homeopathic sugar 

 globules. 



July is the month to look for them under chestnut trees in woods. 



Genus IX. STEMONITIS. 



Sporangia elongated, cylindrical, peridium delicate, evan- 

 escent. Capillitium reticulate, springing from a dark pene- 

 trating stem, or columella. 



S. fusca. Roth. Dark-brown Stemonitis. 



Sporangia, cylindrical, pointed at the apex, peridia 



fugacious, exposing the beautiful network of the capillitium. 



Spores dark brown. 



This is quite common on decayed branches of trees lying on the ground 

 all through the Valley.
