424 MvurRILL: POLYPORACEAE OF NorTH AMERICA 
Cycloporus Greenei (Berk.) 
Cyclomyces Greenet Berk. Lond. Jour. Bot. 4: pl. rz. 1845. 
This remarkable plant has been eagerly sought for by collec- 
tors since its discovery in New England by Greene and still the 
number of specimens found is hardly a dozen. It may at once be 
distinguished from all other pore-fungi by its concentric, gill-like 
tubes and central stem. It grows on the ground in woods. 
Specimens have been examined from Massachusetts, Greene, 
Sprague; New York, Peck; Connecticut, Earle; New Jersey, 
Gentry ; lowa, McBride ; West Virginia, Nuttall; Vermont, Far- 
low. Five of these collections are in the herbarium of the New 
York Botanical Garden. 
Globifomes gen. nov. 
Hymenophore large, woody, encrusted, perennial, epixylous, 
compound ; context ferruginous, punky, tubes cylindrical, thick- 
walled, stratose : spores ovoid, smooth, ferruginous. 
The type of this genus is Boletus graveolens Schw. (Syn. 
Fung. Car. 71. 1818), a rather rare plant first found in Georgia 
and the Carolinas, but later discovered as far west as Iowa. The 
genus is readily distinguished among its allies by its compound 
pileus, which consists of numerous small, closely imbricated 
pileoli united into a compact rounded mass. 
The genus Xy/opilus of Karsten (Hattsv. 2: 69. 1882), 1s 
also described as having a compound pileus, but Xy/opilus crassus 
(Fr.) Karst., its type species, is very probably only an abnormal 
form of a European species of E//vingia ; and even if this type 
plant were found to be normal the genus G/obifomes would remain 
sufficiently distinct.

This species was first sent to Schweinitz from Georgia, but was 
later found in North Carolina. Plants sent from Ohio to Berkeley 
were thought to differ sufficiently from those growing on oak to 
justify a new name. The heavy odor of the fruiting plant is
