- ^!!-T ^i^rT' '''?' ^^escribed by von Sclireiik*, as causing a 

 White Eot of the lied Cedar {Juniperus mrginianus) in the 

 eastern United States, characterised by the formation of long holes 

 m the heart-wood. The African specimens agree well with his 

 description both of the sporophore and of the type of disease 

 caused by the fungus. The species is recognisable bv the yellowish 

 pores, and the brick-red colour of the flesh and the older 'layers of 

 tubes. :Murrillt has described Fores Earlei (Murr.) Sacc. & D. 

 Sacc, also on Juni-perus, which he states is closely related to F. 

 junipcrinus, but differs in being more rimose, having larger pores, 

 and lacking the annual projecting margins of the older tube layers 

 which occur m the two original specimens of F. junlperinus. The 

 descriptions of the tAvo species, however, differ only in minor 

 details, although Hedgcock and Longil: have maintained that they 

 are distinct and cause different types of '' rot." 



Of the two specimens from East Africa one is broadly ungulate, 

 but little cracked, and velvety tomentose, especially at the margin; 

 the other is much more rimose and elongated, with scarcely any 

 tomcntum, agreeing, therefore, in habit with " F. Earlei." The 

 pores in both reach the edge of the pileus, where, however, they 

 are not properly developed; and in one specimen, in which two 

 seasons' growth of pores is visible, the pores of the last season are 



mm 



so that the differences in pore-size, given as one of the marks of 

 distinction for the two species, may be found in one and the same 

 specimen.
