ol. P. connexum Link. Greenfield, Sept., 1896. (Harvey.} 
Abundant on dead wood and bark. Included by Lister in P. 
compressum Alb. & Schw. Our specimens answer to P. affine Rost. 
nearly. 
92. P. imitans Racib. Orono, Oct., 1896. (Harvey.) On moss as- 
sociated with Avcyria and Diderma, scanty. A small species with 
sporanges .5 mm. diameter and liable to be overlooked. Mr. Mor- 
gan says of a specimen sent him “its large sharp pointed nodules 
are apparent even under a 34-in. objective.” 
93. P. ornatum Peck. Greenfield, Sept., 1896. (Harvey.) On 
dead wood. Morgan says “ this is a fine species and yours is an 
elegant specimen.” 
94. Physarum diderma Rost. Orono, Oct., 1896. (Harvey.) 
Mr. Morgan made the following note on a specimen sent him: 
“This is exactly like my specimens, which I refer to P. diderma 
Rost. I have found it only twice and distributed it to Rex, Mc- 
Bride and Sturgis who agree with me. I do not regard it as P. 
diderma Lister.” This is a rare species heretofore only collected 
by Mr. Morgan and only twice by him. To find it in Maine is 
interesting. 
95. P. striatum Fr. Western Sisters’ Is., Penobscot Bay, Aug., 
1896. (Harvey.) We sent Mr. Morgan a specimen and he says 
‘It is referable to the above species. I have the yellow form also, 
which is P. aurantium Pers. From what little material I have, I 
am inclined to think the two may stand for a good species.” 
Both have disappeared from Rostafinski’s monograph and from 
Lister’s work. 
96. Fuligo candida Pers. Head of Pamedomcook Lake, Oct., 
1895. (Harvey.) Two specimens taken, which were referred to 
Mr. Morgan who makes the following note: “I never saw any- 
thing like it. It is not Fuligo cinera Schw. The spores are oval 
to oblong, minutely warted, 10-11 x 9-10 mic. and the lime nod- 
ules are different. The specimens are good ripe ones showing 
the internal structure nicely. We will call it F. candida Pers. The 
cortex is whitish, fragile, and soon breaking into small patches. 
This form is included under Hxigo septica Link (Gruel) by Sac- 
cardo, but is very different. Persoon’s species should be restored. a 
Q6a. Fuligo muscorum A, &S. Eastport. Prof. W. G. Far- 
low. Omitted from our former list. :
