SI. Ganoderma curtisii (B.) Murrill, Bull. Torr. Club 29 : 602. 
1902. 
Poly poms curtisii Berk. 
Closely related to the next species, but probably rare in 
this state. Said to grow on ash and maple wood. 
82. Ganoderma sessile Murrill, Bull. Torr. Club 29 : 604. 1902. 
This species has always been known to American col- 
lectors as Polyporus lucidus (Leys) Fr. Collectors should 
have no trouble in identifying it, as it is the only species 
with a varnished pileus that is at all common here. It 
occurs both with and without a stipe, but when the stipe is 
present it is always lateral. Common at the bases of stumps 
of different deciduous trees.

83. Cerrena unicolor (Bull.) Murrill, Jour. Myc. 9 : 91. 1903. 
Boletus unicolor Bull. 
Known as Daedalea unicolor (Bull.) Fr. The collector 
who finds this plant for the first time is very likely to decide 
immediately that it belongs to the genus Coriolus, as the 
thin, leathery, pileus and irpiciform hymenium would 
indicate. But the hymenium is at first plainly labyrinthi- 
form, and only becomes irpiciform with age. The hymenium 
is at first white but later takes on a darker color. The 
pileus is densely strigose- villous, multi-zonate, and frequently 
covered with a green alga. Common on all kinds of dead 
deciduous wood. The writer frequently finds specimens 
which have continued their growth the second year from the 
margin of the first year’s growth.

Agaricus quercinus L. 
On dead oak wood. Said to be common in some parts of 
the state.

85. Daedalea confragosa (Bolt.) Pers. Syn. 500. 1801. 
Boletus confragosus Bolt. 
Trametes rubescens Fr. is a thin form of this plant. It is 
the only species of the genus that is at all common here. 
Various conditions of the hymenium are found, grading 
from strictly poroid to labyrinthiform and lamellate, some- 
times all stages being found in one plant. The hymenium 
changes from white to reddish brown when touched. Found 
from August until December, on dead willow wood.
