NOTES ON MYCETOZOA. 267 
at numerous points. Stalk varying in length, usually very short, 
filled with spore-like cells. Capillitium a loose net of variously 
branching threads, which expand on iu into a dull red column 
m 
awn end of fir-log in wood-stack. In some sporangia the 
threads ‘of the Cenk are uneven, with constrictions and fusi- 
orm expansions, 7-8 » diam. 
A specimen from ‘ion mark, No. 893 in the Kew collection, 
named by Dr. Cooke Arcyria Ocrstedtii, consists only of capillitium, 
and, though somewhat darker in colour, is no doubt the same species 
as my gatherings, as is also No. 154, from New Zealand, named 
“arco yria fuliginea C.& M. This, again, is more fuliginous in tint, 
all other respects, including the persistent portions of the 
ea gium-wall, it is precisely the same as the English aero Ss 
I cannot doubt that Dr. Cooke is right in his naming of the 
Arcyria nutans Bull. that it is a question whether A. Cerstedtii is 
not merely a well- ome variety of that species. In A. nutans the 
ee et above the basal cup is nearly always evanescent, 
but in i itibeens a persistent ‘fragment eA ss found; the 
dupchticesi: is variable, and in som essenti 
porangia sé 
similar to A. Oerstedtii. The real ae Naivohoee, would 
appear to resolve itself into one of colour, and, Ame ae mind the 
brown and ochraceous forms which are met with in A. ferruginea, 
the question of colour can scarcely bees held to be of specific 
importance.
