Notes on Malyan Mycetozoa. A. R. Sanderson. 247 
Cienkowskia reticulata Rost. I had three gatherings of this 
species. One was a very fine colony spread over the bases of 
palm leaves lying on the ground and over some leaflets of 
Hevea. The portions which were dehiscing showed the deep 
orange base of the sporangium lying close to the substratum, 
as well as the delicate pale yellow capillitium and dark spores. 
This species is unmistakable after being once seen in the field. 
A second specimen, consisting of two small colonies, was found 
also on palm; a third small growth was on a somewhat decayed 
jungle log. 
Craterium minutum Fries. Only once have I gathered a very 
meagre colony of this species which is so common in England. 
It was on some leaves and débris on the edge of a jungle swamp 
where many leaves and twigs showed tracks of plasmodium. 
Diderma arboreum G. Lister and Petch. This species occurs 
on the living trunks of coconut palms and Hevea but apparently 
is not very common. I have found fairly large colonies on a 
decayed log in the jungle, and once I noticed it on a living 
Hevea tree, immediately after felling, at a height of about 30 ft. 
D. effusum Morg. This species has been observed on dead 
leaves, but is apparently not common. 
D. hemisphericum Hornem. This occurs in similar situations 
to the preceding; I have once seen it on bases of coconut leaves. 
Diachea leucopoda Rost. I have twice found very extensive 
growths of this species, once on decaying Hevea leaves and 
twigs, and once on dead leaves of Gardenias and Crotons. 
Didymium Clavus Rost. This is very common in small widely 
scattered colonies on decaying leaves of many kinds. 
D. nigripes Fr. One gathering only. 
Stemonitis fusca Roth. This species is very frequent on rotting 
jungle logs, especially those in drier situations, and on the under 
surface of Hevea tap roots which have been dug out because of 
disease. It also occurs very commonly in fire-pits on half-burnt 
Hevea and on many other logs left on the ground after a “ burn 
off,’ i.e. clearing the land of jungle. 
S. splendens Rost. Although not nearly so frequent as S. fusca 
this is fairly common, especially on Hevea logs, and is one of 
the earliest to appear; the sporangia are frequently very long 
and densely fasciculate. 
S. ferruginea Ehrenb. This is almost as common as S. fusca 
and occurs in similar situations. Usually the development takes 
place in a series of somewhat scattered small groups. 
Comatricha laxa Rost. This is represented by two small 
gatherings. 
C. pulchella Rost. This species has occurred twice, once on 
leaves of Gardenia and Thunbergia in Selangar, and the second
