606 Murritt: THE PoLtyporRACEAE OF NortH AMERICA 
1891-1892. This beautiful little plant is closely related in habit 
and general appearance to the American species of Ganoderma 
occurring farther north, but it is of much smaller size and its 
spores are quite distinct in form, size and color. It is possible 
that the specimens I have are not quite mature. 
5. Ganoderma Oerstedii (Fries) 
Polyporus Oerstedi Fries, Nov. Sym. 63. 1851. 
Pileus reniform, ungulate-applanate, gibbous at the base, a foot 
in diameter ; surface horny-incrusted, very glabrous, adorned with 
shallow furrows, which almost disappear with age, shining reddish 
chestnut becoming almost black ; margin very obtusely truncate 
and marked with concentric furrows, the upper annual growths 
exceeding the lower; context partly hard and horny and partly 
floccose, umbrinous next to the tubes, more tawny beneath the 
cuticle, very thin in older specimens, the tubes forming the prin- 
cipal part of the pileus: tubes contiguous and hence indistinctly 
stratified, 3-5 cm. long, umbrinous within, mouths lighter in color, 
dissepiments entire, obtuse: spores broadly ellipsoid, truncate, 
very dark yellowish-brown, abundantly and roughly echinulate, 
Il xX Oy. 
Two imperfect specimens of this plant are in the herbarium of 
the New York Botanical Garden, one collected by C. L. Smith in 
Nicaragua, and the other by C. T. Townsend on an orange tree 
in Jamaica. These specimens, while corresponding with the 
Friesian types at Upsala, hardly justify any considerable departure 
from the Friesian description.

6. Ganoderma zonatum sp. nov. 
A soft laccate fungus of medium size marked with numerous 
tawny and chestnut-colored zones. Pileus very soft-corky, S€S~ 
sile, dimidiate, applanate or convex above, concave below, g!4- 
brous, zonate, not sulcate, 5 x 7 x 1.5 cm.; margin velvety, acute, 
becoming obtuse and concolorous: context very soft, floccos®, 
radiate-fibrous, concentrically banded, 0.5 cm. thick, chocolate 
brown: hymenium velvety, not stratose, tubes I cm. long, 3-4 ad 
a mm., umbrinous within ; mouths white to umbrinous, regular, 
polygonal, stuffed at first with whitish material, covered 0.5~? vars 
from the margin with yellowish or reddish varnish ; dissepimen® 
entire, obtuse to acute: spores elongated ellipsoid, smooth, p4 
yellowish-brown, 8-10 x 4-6 p.
