This is our common species; not abundant, but with us 

 from midsummer to October every year. It comes to 

 fruit often under board walks, steps, and in similar 

 inaccessible localities, where it speedily makes its 

 presence felt to the annoyance of a household or whole 

 neighborhood. 



962. P. duplicates, Bosc. 



Less common than the preceding species, similar to it 

 but smaller and probably distinct. Found occasion- 

 ally in the borders of woodlands, hazel-thickets; 

 pungently odorous. 



963. P. impudiciis, Linn. 



Kare. Occasionally met with in umbrageous woods 

 where leaves accumulate from year to year. The odor 

 characteristically pungent. 

 MUTINUS.

Earely, but constantly in all the eastern part of the 

 state. 



965. M. caninus, (Huds.) Fries. 

 Very rare. 



966. M. brevis, B. & C. 



Apparently rare. Small objects as they are, they are 

 possibly even more pungently odoriferous than any 

 of the rest. They seem to rise in colonies in fields 



and gardens, even in cellars.
