In a recent circular on “ Wood Decay in Orchard Trees in Cali- 
fornia,” by W. T. Horne, attention is called to the frequent occur- 
rence of rots affecting orchard trees, in many cases apple and 
stone-fruit trees being seriously attacked by wood-destroying 
fungi. The author recommends cutting out, disinfecting, and 
coating the wounds with asphaltum. The trees should be inspected 
at the end of the summer and the disinfection renewed if necessary. 
Dr. N. Patouillard has an article in the Philippine Journal of 
Science for March, 1915, on fungi sent to him from the Philip- 
pines by Professor C. F. Baker. The article contains a long list 
of determinations and also the following new species : Septo- 
basidium laxunt, Hymenochaete pavonia, Duportella velutina, 
Duportella Raimundoi, Leucoporus ameides, Leptoporus Bakeri, 
Leptoporus armatiis, Hexagona lachnochaeta, Elmerina foliacea, 
Daedalea philippincnsis, Ganoderma Bakeri, Ganoderma plicatum, 
and Crinipellis fragilis. 
A bulletin on “ Insects as Carriers of the Chestnut Blight Fun- 
gus,” by R. A. Studhalter and A. G. Ruggles, was recently published 
by the Department of Forestry of Pennsylvania, in which experi- 
ments with ants, spiders, beetles, flies,^ and other kinds of insects 
are outlined, and it is shown conclusively that insects are largely 
instrumental in the dissemination of the chestnut canker and many 
other injurious fungi. The bulletin also contains an interesting 
historical summary of the experiments thus far made with insects 
as carriers of fungous spores. 
Professor E. A. Burt, mycologist of the Missouri Botanical 
Garden, visited the Garden February 12-17 to examine the col- 
lection of Thelephoraceae in the mycological herbarium. He 
has been publishing a series of papers on this important and 
difficult family, which he hopes to complete within the next three 
years. He will then prepare descriptions of the species for pub- 
lication in North American Flora. Professor Burt’s visit was 
made the occasion of a dinner to over twenty local mycologists 
and other botanists, given by Professor Harp>er on the evening of 
February 16 at the Columbia Faculty Club.
