the conclusion was reached that while the fungus might for many 
generations aid the host in the elaboration of protein compounds 
that were absorbed by the latter, ultimately, though very gradu- 
ally, the fungus proved a destructive agent. 
2. Studies on some mycelium and fungi from a coal mine: PRo- 
Fessor Gro. F. Atkinson, Cornell University— On the 14th of 
September the speaker explored abandoned portions of the 
Algonquin coal mine near Wilkesbarre, Pa., for the purpose of 
studying the mycelium formations on the doors in the gangways, 
and on the wood props which are used to support weak places 
inthe roof above. Several flash-light photographs were made 
of the remarkable displays of the mycelium some four hundred 
feet below the surface, and of some of the fruit forms. Mature 
fruit collected has been determined as follows : Polyporus verst- 
color, P. annosus, Coprinus micaceus, Stropharia, Hymenochete, 
Merulius, etc. The paper was illustrated with lantern views. 
3. Ls there a basidiomycetous stage in the life-history of some Asco- 
mycetes ?: Dr. E. A. Burt, Middlebury College.— Mr. Burt has 
ee studying a case of undoubted association of Graphium 
siganteum (Pk.), otherwise known as Dacryopsis Ellisiana ( Berk.) 
re With the ascomycete Lecanidion leptospermum (Pk.), 
de nown as Holwaya tiliacea E. & E. Dacryopsis Ellisiana was 
Scribed and figured by Massee as a tremelloid basidiomycete. 
ihe sk 2 been unable, by the study of collections made in 
prize ' of August, October, November, and December, to 
Pm — hae observations on the basidiomycetous nature of 
nn piaes and therefore is unable to conclude, for the 
Lecanidi at it is a basidiomycetous stage of the ascomycete 
ton leptosperma. 3
