mycelial threads. To distinguish this form, that we have now frequently met 

 with, we propose the above varietal name. This form is also of interest as, in 

 one case, having manifested parasitic features of some economic importance. 



Victoria: In 1917, Mr. C. C. Brittlebank. of the Department of Agriculture 

 of that State, sent us specimens of a Scleroderma, which we now refer to this 

 variety, found at Dandenong in June, which had killed off a number of rose 

 trees. He says, "There is not the slightest doubt as to the parasitic nature, as the 

 mycelium was traced right through the outer coverings into the cambium and 

 underlying tissues." The specimen sent was unopened with a thick peridium 

 supported on an irregular reticulated mass of thick mycelial strands forming 

 a mass larger than the peridium itself, spores shaggy, acicular, dark brownish, 

 12 to 155 fi, hyphae 7 ix thick. 



South Australia: Eagle on Hill, June, spores densely echinulate, 11 fi; an 

 unexpanded plant from near Overland Corner (this locality is doubtful) is 

 probably also this variety — the thick-walled peridium is supported on a very 

 irregularly rugose somewhat flattened stem without fenestrations, 3 inches long 

 and f inch thick in places, spores densely echinulate, 122 to 155 yu,; an old 

 specimen from Overland Corner, December, in which the peridium has burst 

 into stellate, sometimes subdivided lobes, supported by a short thick stem, f inch 

 long and ^ inch broad, attached below by a constricted neck to a mass of 

 irregularly to nobby, somewhat flattened, not definitely fenestrated compacted 

 mycelium forming a root below ground, 1 inch long and broad, spores "smooth" 

 (probably the result of weathering, the specimen having been long exposed), 

 spherical, yellow-brown, 52 fi; Eagle on Hill, another collection, identified as 

 S. flavidimi by Lloyd (No. 692), peridium splitting into up to 8 lobes, root 

 3 inches long x 1:^ inch wide, dense but spongy above, passing below into inter- 

 lacing mycelial strands, spores mulberry-like, 9 to 12 fx,.
