correct. Some of the species are among the earliest arrivals 

 at toadstool lawn partigs, and some are the last to leave." 



During the past season P. retirugus was exceedingly abun- 

 dant in the flower beds on the campus at the Connecticut Agri- 

 rultural College, and could be collected almost any day 

 throughout the entire season. P. solidipes is an attractive 

 looking plant. Its large size, pure white color, and symmetri- 

 cal shape give it a pleasing individuality.

POLYPORACE^ Fr. Tube-bearing Fungi. 



The Polyporacese are in most cases easily distinguished 

 from members of other families by the characteristic spore- 

 bearing surface, which is composed of more or less regular, 

 distinct tubes, with conspicuous or inconspicuous mouths. 



The substance of the fruit-body in some genera is similar 

 to the fruit-body of the Agaricacea;, but the spores are pro- 

 duced within pores on the lower surface of the cap. In some 

 genera these pore-bearing surfaces are variously convoluted 

 and ridged so that they resemble the gill-bearing Agarics ; in 

 other genera they are more or less torn, somewhat resembling 

 genera of Hydnaceje. The family is a large one, and contains 

 many edible species, especially in the Boletus group, but, as in 

 many of the Agaricacese, they are frequently too badly infested 

 by larvae to be used for food. 



The plants are found abundantly in all sections of the state, 

 growing on trees either in a parasitic or saprophytic manner, 

 and many, especially the fleshy forms, are found on the ground, 

 in decaying leaves or other vegetable substances. 



The plants vary much in their consistency, some being 

 flesh}-, others leathery or woody. Some are annuals, others 

 are perennials, adding new layers of growth each year. In 

 many species of Fomes, the new spore-bearing surface grows
