lieve Mucronella fascicularis should be classed as a Pterula, as Bres- 

 adola classed my Samoa collection. Certainly it is cogeneric with 

 several tropical species, as Pterula Winkleriana and Pterula Sprucei 

 (which, however, passes as a Hydnum in Saccardo). The substance 

 is rigid and cartilaginous, not soft and fleshy as in preceding section.

MUCRONELLA ULMI. Described by Peck growing on Elm. It is similar 

 to Mucronella fascicularis, in its habits of growth, but is much smaller with teeth 

 1 to \% lines long and fewer in a fascicule.

POLYPORUS MYLITTAE, FROM E. CHEEL, AUSTRA- 

 LIA. (Figs. 728 to 732.) There occurs in Australia a frequent tu- 

 beraceous growth, which was used by the natives as food and called 

 "native bread" or "blackfellow's bread." While it was supposed 

 to be of fungal origin, its nature was unknown for many years, and 

 Berkeley (in 1839), presuming that it belonged to the Tuberaceae, 

 although he records that he could not find any spores, named it 

 Mylitta australis. It was compiled in Vol. 8, Saccardo under the 

 uncertain genera.
