86 MALFORMATION OF THE LEAVES OF BEYERIA LINEARIS. 
the microscope presented a maze of most beautiful mycelium, 
the extending branches of which seemed invariably to bifurcate at 
an angle of (or near) 60?, with short ones, consisting of one to 
several celis, at right angles to the main direction. 
The more slender portions of the * stem" and most of the 
branches showed a distinct bead-like cell-strueture, while in the 
wider parts the cells appeared to have joined consecutively by 
absorption of the adjoining cell-wall. An outer and inner in- 
tegument could be plainly discerned, and an irregular canal 
extending within the latter, filled with the brownish-yellow rod- 
like bodies noted above as entangled among the threads of the 
web mentioned (or something extremely similar, but much smaller). 
The prevailing form of the cells appeared to be that of a trape- 
zium ; but rhombic and hexagonal forms were by no means rare. 
The works of reference at my command are not sufficient to 
determine even the genus ; thus I am unable to assign a name to 
this remarkable object, but hope that the sketch and the accom- 
panying specimen will suffice to enable one of the distinguished 
mycologists of the Linnean Society to assign a suitable appella- 
tion to it. If new, I would beg to suggest to name it specifically 
after my highly valued friend Mr. Thomas D. Smeaton, of Adelaide, 
who has most unobtrusively for many years promoted micro- 
scopical studies very assiduously, and to whom I am very much 
obliged for placing a valuable microscope at my command. 
[JVote.—The sketch and specimen sent by the author were 
insufficient to determine the fungus; the former is therefere
