Mycetozoa at Porlock in October 1920. N.G. Hadden. 15 
where this moss and Sedum anglicum were almost the only 
plants which had succeeded in obtaining a roothold amongst 
the scree. Some rotten pine and larch logs lying on the hillside 
above Smallacombe were covered with rich growths of Collo- 
derma oculatum, Enerthenema papillatum, Comatricha elegans, 
Stemonitis ferruginea, S. herbatica (with very lax capillitium), 
Licea flexuosa and a small development of Dianema corticatum, 
a species which does not appear to have been obtained in 
southern England previously. It so closely resembles Licea 
flexuosa in the field that it is easily overlooked, but the pinkish 
colour of the spores in mass (instead of olive) is a help in re- 
cognising it. On very wet moss by a spring side Fuligo mus- 
corum appeared, one inconspicuous ripe aethalium along with 
the more showy apricot plasmodium which matured in-doors 
after a couple of days. On an old ash tree growing near the 
mouth of the combe I detected several of the tiny grey hemi- 
spherical sporangia of Badhamia affinis perched among tufts of 
Orthotrichum and Frullania some five feet from the ground. 
As each sporangium grows by itself it is by no means con- 
spicuous, but though only recorded in Britain from Aberdeen- 
shire and Cornwall it is quite likely to be found anywhere when 
carefully searched for, nearly all the arboreal Mycetozoa being 
inconspicuous but evidently of wide distribution. Similarly it 
1s not likely that Japan, West Somerset and Aberdeenshire are 
the only localities for the typical Hemuitrichia minor! It seems 
impossible to lay down any rules as to searching for the arboreal 
species; most of Mr Cran’s wonderful Scottish finds have been 
upon exposed trunks sparsely clad with lichen and moss, here 
my only success has been on ash trees in damp sheltered woods 
where mosses and lichens luxuriate on the bark. On the same 
tree which yielded B. affinis I collected some freshly emerged 
lemon-yellow sessile sporangia growing on moss low down on 
the trunk; by the time I reached home these sporangia had 
turned a dull green, the next morning they were a bright grass 
green; they finally matured into the yellow plasmodiocarps of 
the rare Badhamia nitens var. reticulata. 
While gathering these interesting Mycetozoa it was a never- 
failing source of pleasure to listen to the belling of red deer stags, 
eager for a battle with a rival from some distant combe, to the 
hoarse croaking of ravens and the wild mewing cries of buzzards 
as they soared high overhead. 
Since the above was written I have had the pleasure of finding 
about thirty sporangia of the remarkable Diachaea certfera 
G. Lister (see Journal of Botany, vol. L1, Jan. 1913). The white 
plasmodium and newly developed sporangia occurred on the 
Hepatic Pellia epiphylla on a steep bank close to a small stream
