NOTES AND BRIEF ARTICLES 
Mr. A. S. Rhoads, assistant in forest botany at Syracuse Uni- 
versity, visited the Garden April 20-23 to consult the collection 
of Polyporaceae in the mycological herbarium. 
Mr. C. C. Hanmer, of East Hartford, Connecticut, has sent in 
a very interesting specimen of Russula flava Romell collected by 
him at Kineo, Maine, in August, 1911. The specimen grew alone 
beneath a log covered with clusters of Armillaria mellea and one 
of the “ shoestring cords ” of this fungus came in contact with 
the moist upper surface of the Russula and developed a tiny 
hymenophore of the Armillaria, which in the dried state is nearly 
2 cm. high. Spores from the Armillaria clusters fell plentifully 
upon the Russula and the stipe of the young Armillaria was partly 
imbedded in the surface of the Russula, strongly suggesting to Mr. 
Hanmer at first glance that it had developed in some unusually 
rapid way from one of these spores. A tiny bit of black “ cord ” 
projecting from the base of the young stipe tells' the story. It 
might be interesting to students to follow this up with a few ex- 
periments. 
The subject of edible mushrooms has become very popular of 
late and many inquiries have been received regarding reliable lit- 
erature. It can now be stated that there is in press and very soon 
to appear a large colored chart and a descriptive handbook con- 
taining the principle edible and poisonous species of fungi found 
in America. It is hoped that much safe and useful information 
will be disseminated by means of this long desired publication.
