to have it examined. Some time before a specimen had been 
discovered on the ground in San Bernardino Co., California, and 
described as a new mineral, which was named Bernardinite. 
A fungus very similar to this is sometimes found in the pine 
woods of Michigan, and is described in Vol. II. of the Journal of 
Mycology, by W. W. Calkins. The fungus is mostly composed 
of resin granules formed around knots of mycelium, and contain- 
ing one or more curiously shaped bodies, sometimes resem- 
bling branching bast cells, which are evidently outgrowths of the 
mycelium. In some places are mycelial strands composed of 
nearly parallel hyphz. The pores of the fungus were worn away, 
only indications of their presence remaining, and no spores could 
be found; moreover, no authentic specimen was at hand for 
identification ; the real identity of the fungus is, therefore, still an 
open matter. The method in which the resin was secreted and 
deposited is also a question for further investigation. 
Two other fungi may be briefly noted. One on Muhlenberg- 
ta appears like an Evysiphe with the low power of the micro- 
scope, but the conceptacle is crowded full of colorless cells or 
spores, with thick walls and granular contents. The other is a 
superficial fungus on bark of orange, and will probably prove to 
be a new species of the genus Phymatomospheria. .

Botanical Notes. 
A Double-headed Rudbeckia. Yesterday while gathering a 
handful of heads of Rudbeckia hirta avery unusual specimen 
was found that seems worthy of passing notice. Instead of a 
single dark cone with its long fringe of yellow ray-flowers, there 
were two closely joined upon the same stem, and each was pos- 
sessed of a full circle of the rays. The heads were so close to- 
gether that both were equally thrown out of the normal position, 
one facing the east and the other the west at an angle of about 
forty-five degrees. BYRON D. HALSTED.

An Economical Maple. In the August BULLETIN, Mr. Sar-
