A Key to the Perennial Polyporaceae of temperate 
North America, by William A. Murrill, is published in Torreya. 
4: 165-7, November 1904. The genera which are used in the 
paper, as well as the important characters on which the divisions 
are made, can best be shown by transcribing the first section of 
the Key, which is as follows: 
Hymenium at first concealed by a valva.Crytoporus 
Hymenium free from the first — 
Surface covered with reddish varnish, context corky.Ganoderma 
Surface not covered with reddish varnish, or, if so, context woody — 
Context and tubes white or pallid.Fomes 
Context and tubes brown or dark red — 
Hymenophore subsessile, caespitose, arising from a com¬ 
mon trunk or tubercle.Globifomes 
Hymenophore truly sessile, dimidiate or ungulate, sim¬ 
ple or imbricate — 
Pileus covered with a horny crust, context punky.. 
.Elfvingia 
Pileus not covered with a horny crust, or, if en¬ 
crusted, context woody, ferruginous... Pyropolyporus 
Context dark purple or black.Nigrofomes 
Panaeolus acidus is a new species described by D. R. Sum- 
stine in Torreya, 5: 34, Feb. 1904. In general it resembles Psilo- 
cybe foenisecii (Pers.) Fr., but is readily distinguished by the 
black spores. It was growing in a cluster on the bottom of a box 
in a cellar. The box contained a large bottle of acetic acid which 
had been broken and the contents emptied on the bottom of the 
box. The plant grew on this saturated wood. 
A LIST OF SEVENTY-SIX SPECIES, THE BoLETACEAE OF PENN¬ 
SYLVANIA, by D. R. Sumstine, is given in the December No. of 
Torreya, 1904. This is a remarkably large number, being nearly 
tw r o-thirds of all the species known in the United States. 
The Report of the State Botanist, 1904, Charles H. 
Peck, New York State Museum Bulletin 94 (Botany 8) : 1-58 
Plates 87-93, P-R, July 1905, is one of the monthly publications 
of the New York State Education Department (Bulletin 349), but 
it apparently is a part of the 58th Report if we interpret correctly
