in Stemonitis fusca, this species appears to produce an 
sahalinie form, which is represented in the Kew collection by 
No. 665, under the name of Stemonitis confluens Cke. & Ellis, from

Si ing the above I have gathered large quantities of 
Stemonttis alae ns from several stumps of Scotch fir near Lyme 
R The trees were felled three or four years ago, and the w od 
is hard. The white e plasmodium emerged in large patches, several 
inches across, and was protected from sun and rain to insure perfect 
development. It is an unusual form, inasmuch as the stalks are 
very slender, rising from-a silvery or purplish hypothallus, and with 
scanty, sparingly branched capillitium ; the superficial threads are 
widely distributed, scarcely forming a net, and are occasionally 
connected with broad, membranous, and fringed spenrihnwenn The 
spores in mass are rich red- brown, when magnified 560 diam. 
violet-bro and apparently s de 1 a 
faint close reticulation can be discovered of the same character as 
is rin, this I have 
swarm-cells emerge in vast numbers when the 
spores have remained in water for two or three hours. Specimens 
gathered on stumps oa yards apart have the capillitium and spores 
sdentieal in all resp eee
