is the peculiar, smooth, “ glace kid glove ” feeling of the surface. 
They justify Professor Peck’s characterization “ admirahilis” in 
every respect. 
With the aid of Dr. House, the state botanist, I was enabled to 
examine all of Peck’s specimens of this fungus in the herbarium 
at Albany. One specimen collected by S. H. Burnham on an 
apple tree trunk at Pike Pond, New York, July, 1910, has a 
margin that is beautifully and evenly scalloped. The surface is 
even, light-straw-colored, and has characteristically a “ kid glove 
feeling.” There are one or two faint zones near the margin 
formed by depression but there are no color differences. There 
is a slight tendency to splitting up or pileolation, there being one 
accessory pileus. The stem is much reduced or even lacking. 
There is another specimen from Crown Point, N. Y., collected by 
Dr. Peck, which is a cluster of three plants now in very poor con- 
dition. No host is given but it is evidently the same species. 
I have found Polyporus admirahilis only on apple trees, but it 
is to be noted that there are two specimens in the State Her- 
barium under this name that are of special interest, since they 
were collected on other hosts than the apple tree. • The one on 
ash found by S. H. Burnham at V'aughans, N. Y., July 6, 1907, 
and mentioned in the report for 1907, p. 12, is a dead-white form 
with minute pores. Two plants are joined together at their mar- 
gins. The stems are quite distinct and prominent. The other 
specimen was collected by Mr. Burnham at the same place August 
25, 1911, on a “living fallen butternut.” The stem is central or 
slightly eccentric and more pronounced. All of these specimens 
are pure-white with no trace of straw-color,- otherwise they re- 
semble those growing on ash. These forms on the ash and butter- 
nut appear to be somewhat different from those on the apple tree 
and are certainly more like specimens of P. Underwoodii in IMur- 
rill’s collections at the New York Botanical Garden, but whether 
these differences would hold in a larger range of specimens and 
whether the spores of these forms would grow on the apple tree, 
are questions of considerable interest and must be further studied. 
Another specimen in the Albany Herbarium, which plainly should 
be called P. admirahilis, bears the name Polyporus Underwoodii.
