solid, hard, squanuilosc, whitish, sometimes brownish toward the 

 base; spores eUipsoid, .0002-0003 of an inch long, .0001-.00016 

 broad. 



Pileus 1-1.5 inches broad; stem 1-1.5 inches long, 1-2 lines 

 thick. 



Decaying wood. A small but attractive species. 



There is a common form in which the lamellae are obliterated 

 or overrun by a mass of mycelium or compact tomentum. This 

 was at first thought to be a diseased or abnormal state of the 

 species and was characterized as transforming the lamellae to a 

 " woody mass " or " spongy mass." This form was later thought 

 to be a distinct species and was described under the name Lento- 

 d i u ni s q u a m u 1 o s u m Morg. But since the two forms are 

 sometimes found growing together on the same stump or log 

 and as they both produce spores of the same character it seems 

 better to consider them both forms of one species. We may sup- 

 pose this abnormal form to develop the hyphae of the hymenium 

 in excessive abundance and that these hyphae bear spores directly 

 without the intervention of basidia. The abnormal form might 

 in such a case be considered in the light of a conidial state of 

 the species. 



Lenthius sulcatus Berk. 



Panus fulvidus Bres. 



SULCATE LENTINUS 



Pileus fleshy, thin, tough, conic becoming hemispheric or con- 

 vex, cracking on the surface and forming irregular scales, virgate 

 toward the margin, sulcate on the margin, reddish or tawny, often 

 darker in the center ; lamellae subdistant, rounded behind or 

 emarginate, slightly adnexed, obscurely dentate on the edge, white 

 or pallid ; stem central, short, solid, sometimes narrowed down- 

 ward, pruinose or slightly furfuraceous, white or pallid; spores 

 oblong, .0005-.0007 of an inch long, .00024-.0003 broad. 



Pileus 8-12 lines broad; stem 6-10 lines long, 1.5-3 ^"""^^ thick. 



Crevices of dry wood or old fence rails. Essex county. June. 



A rare species and found but once in our State. In the dried 

 specimens the margin of the pileus is distinctly sulcate and the 

 grooves are paler than the intervening ridges.
