56. Poria borbonica Pat. Jour, de Bot. 4: 198. 1890 



Originally described as follows from specimens collected on 

 bark on Reunion Island : 



" Resupine, dur, compact, entierement gris de souris, marge 

 nulle. Tubes obliques, longs de 5 millimetres, implantes direct- 

 ment sur le support ; pores petits, arrondis, ou ovales allonges, en- 

 tiers, a cloisons minces. Mycelium blanc, floconneux, abondant, 

 entourant la plante d'une large bordure soyeuse. 



" Plante f ormant des plaques denses, larges de 10-20 centi- 

 metres. Le mycelium penetre profondement dans l'ecorce et 

 donne naissance a des couches blanches a la maniere du Poria 

 corticola." 



This species is widely distributed and quite common in tropical 

 regions on dead trunks of mango, cocoanut, etc. When young 

 and fresh, the hymenium is very light russet with a glaucous 

 bloom. The following specimens have been examined :
