97. Badhamia verna Rost. Orono. Me. Oct., 1896, (Harvey.) 
' This is an exceeding rare species. It = Physarum vernum Som- 
merfeldt sent by him to Fries in litt. (See Fries S. M. 3: 146.) 
Rostafinski cites but one other specimen, found at Freiberg by 
De Bary. To find it in this country is remarkable. Lister merges 
it with &. panicea Rost., but wherever placed the species is new to 
this country. The sessile sporanges are hard to detect on the 
mossy logs where it grows. We have never found it but once, 
and then in very small quantity. Mr. Morgan, to whom a speci- 
men was sent, thinks “it is just as near as can be to the specimen 
described by Fries.” 
98. Badhamia capsulifera Bull. Orono, Oct., 1896. (O. W. 
Knight.) Lister puts this under B. hyalina Berk. He says that 
the spores are like those of 2. hyalina Berk. The plasmodium 
from which our specimens come was very large and at one end 
the sporanges were finely obovate and at the other end globose 
and some of the*sporanges were lobed. Some were long stalked 
and others sessile. The large plasmodium would suggest B. 
utricularis Berk. if that is a distinction between B. hyalina Berk. 
and &, wtricularis Berk. Our specimens were regarded as the above 
species by Mr. Morgan, who includes in his description (M. M. 
V., p. 106) B. hyalina Rost. We incline to Massee’s view a 
polymorphous species for the above and B. utricularis Bull. 
99. Scyphium rubiginosum Chev. Orono, Oct., 1896. (Merrill.) 
Nov., 1895. (Harvey.) Mr. Merrill’s specimens were found on 
Moss, sticks and on the base of alders near a brook. My speci- 
mens were found on the base of a fir tree in deep woods. Not 
abundant. 
Orb. DiIpDyMIACEAE. 
100. Lepidoderma tigrinum Schr. Orono, Oct., 1896. (Harvey.) 
Only a few scattered sporanges found amongst moss on the under- 
Side of a declining trunk, two feet from the ground. A rare species. 
Mr. Morgan says it is scanty in Ohio. 
101. Diderma radiatum Morgan=Chondrioderma radiatum Rost. 
Orono,Oct.,1 896. (Harvey.) Scanty specimens were found amongst 
lichens on hemlock bark. Mr. Merrill found this species much | 
More abundant at E. Auburn, showing finely the radiate structure
