THE AUSTRALIAN NATURALIST. Watt 
Specimens of Boletus granulatus, a fungus somewhat re- 
sembling a mushroom in shape, but having sulphur-colored 
pores or tubes on the under surface instead of gills; and 
RKhizopogon lutéolus, a peculiar fungus,- somewhat like a 
pufiball in shape, but always found just under the goil in- 
stead. of an the surface, were also exhibited, and it was 
suggested may probably be another example of symbiosis, ay 
both these species are found under pine trees, especially 
Pinus msignis, and have probably been introduced with 
these species, and symbiotically associated therewith. 
It is interesting to note that attention has already been 
given to Boletus granulatus, having been found under pine 
trees in California, as specimens have been sent, by way of 
exchange, to the National Herberium, Sydney, from the 
Stanford University of Santa Clara County, with the fol- 
lowing particulars—““This is apparently the most abundant 
Boletus of this region, but found almost altogether under 
or near pine trees instead of oaks.’’  . 
Mr. G. Massee, the Mycologist at the Royal Gardens, 
Kew, also states in his British Fungus Flora, vol. i., p. 280 
(1892), that Boletus granulatus is found “‘amongst grass 
under trees, especially firs.” 
ON FLIES FOUND ATTACKING RIPE GRAPES. 
(By Miss Gladys H. Froggatt.) 
I collected these flies under a grape vine trellis in our 
garden ab Croydon. Just when the grapes became fully 
ripe, we had a lot of rain, which caused many of them to 
crack and begin to decay. These jotting bunches attracted 
the honey bees, and also large numbers of flies. There were 
so many different kinds of flies that it seemed worth while 
to collect and classify them. To simplify the difficulty of 
netting the flies among the hanging fruit, bunches of over- 
ripe grapes were placed on a table under the trellis, and 
there the flies, which immediately clustered over the fruit, 
were easily secured with a net. Among the specimens ob- 
etained, the following species have been identified :— 
Apis mellifera.—The common honey bee. 
Musca domestica.—The ordinary house fly which Dr. How- 
ard calls the “typhoid fly’? because if allowed it can trans’ 
fer disease so readily. 
Sarcophaga auwrifrons.—The best known species among 
the ‘‘flesh flies.” It is one of the commonest of those large 
flies which decaying matter always attract.
