LENTINUS Fr. 

 Lcntas, tough or pliant. 



The pileus, or cap, of these plants is fleshy and leathery 

 in consistency, becoming very tough and hard at maturity. 

 The gills are of the same general character, and thin on the 

 margin?, which are toothed. The gills extend down the stem 

 in more or less decurrent lines. 



The stem in the different species is attached in various ways 

 to the pileus. It may be central, or attached at one side of the 

 center (eccentric), or it may be attached at one edge of the 

 pileus (lateral), giving it a shelving appearance- Several spe- 

 cies are exceedingly injurious to wood ; the mycelium, or vege- 

 tative portion of the plant, inhabits the woody tissue, and in 

 many different ways brings about destruction of the cell struc- 

 ture, causing decay. L. lepideus is usually found on railroad 

 ties and is destructive to them. 



Lentinus chrysopeplus B. & C. (golden-cloaked). 



Mansfield, June (52). 

 Lentinus Lecomtei Fr. 



Mansfield, June (T). 

 Lentinus lepideus Fr. (scaly). 



East Hartford, Haunter; Mansfield, Julv (238). 

 Lentinus tigrinus (Bull.) Fr. (tiger-spotted). 



East Hartford, Haunter. 

 Lentinus vulpinus Fr. (hairy like a fox). 



Mansfield, July (2^). 



PANUS Fr. 



The name of a fungus growing on trees, described bv Pliny. 



This group very closely resembles Lentinus, and by mam- 

 authors the species are classed in that genus. The general 

 characters are the same, but the margins of the o-i]l s are en- 

 tire, thus differing from the toothed margins of the gills of 

 Lentinus. 



Panus farinaceus Schum. (mealy). 



East Hartford, Haunter. 

 Panus rudis Fr. (rough). 



South Windsor, Hanmer.
