This is also without fruit, but so characteristic in other respects, that ther 
can scarcely be a doubt of its identity. It kills the stems and branches it 
attacks.

keep them distinct, though some botanists unite them.

Our specimens agree with those Seaed from Dr. Curtis under this name, aa 
but they do not agree with the description of the species as published int ER 
Grevillea. In our specimens the young plant is covered with a compact yel- 
low conidiiferous stratum bearing elliptical conidia .00016 —.0002 long. As 
the stroma increases in size, it becomes naked above, and of a purple-brown 
or chestnut color, which contrasts beautifully with the yellow margin. When _ 
old it becomes darker, but I have not seen it “‘black’’ as described. The 
surface is generally irregular or uneven. The stroma is whitish or pallid — 
__-within, but near the surface it is yellow. The spores vary from Ce 
_ . .0006° in length. I find none, neither in our specimens, nor in those of Dr. 
Curtis, as small as stated in the description. But for the examples of Dr 4
