424 Murkill : Polyporaceae of North America 



Cycloporus Greenei (Berk.) 

 Cyclomyces Greenei Berk. Lond. Jour. Bot. 4: pi. 11. 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; Iowa, McBridc ; West Virginia, Nnttall ; 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. 18 18), 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 Xylopilus of Karsten (Hattsv. 2: 69. 1882), is 

 also described as having a compound pileus, but Xylopilus crassus 

 (Fr.) Karst., its type species, is very probably only an abnormal 

 form of a European species of Elfvingia ; and even if this type 

 plant were found to be normal the genus Globifomes would remain 

 sufficiently distinct. 



Globifomes graveolens (Schw.) 



Boletus graveolens Schw. Syn. Fung. Car. 71. 18 18. 

 Polyporus conglobatus Berk. Lond. Journ. Bot. 4: 303. 1845. 

 Fomes graveolens Cooke, Grevillea, 13: 118. 1884. 



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
