Myxomycètes — Lichenes 
313 
After a wet summer the week of the fungus foray was one of almost 
continuous fine weather. These conditions seen to have been extremely 
favourable for the Mycetozoa. During the foray 81 species were found, 
one of which appears to be new, while 13 others had not been before 
recorded for Scotland. A full list of the species is given with an 
indication of the district in which they were found. Notes are given on 
the more interesting species. The plasmodium of Diderma asteroides 
was found to be white. A new species Lamproderma insessum is dis- 
cribed and figured. A single specimen was found on a lichen on the 
trunk of Acer Pseudoplatanas. Colloderma o cu la tum (Lippert) G. Lister 
is also figured. “Lippert describes minute granules of calcium carbonate 
being present among the refuse matter clothing the sporangium-wall; these 
granules have not been observed in any of the later gatherings, and it 
seems probable that he was mistaken. If this was the case the genus 
Colloderma does not belong to the subcohort Calcarineae (where it was 
placed provisionally in „ Mycetozoa ed. 2), but should be included among 
the Amaurochaetineae , although it differs from all other genera of that 
subcohort in the remarkable gelatinous layer in which the sporangia are 
more or less enveloped.” J. Ramsbottom (London).

The Myxomycete Leocarpus fragilis is recorded as growing on the 
leaves of the moss Dicranum fulvum . The note is accompanied by a 
figure. J. Ramsbottom (London). 
DARBISHIRE, O. V., The Lichens of the Swedish Antarctic Expedition 
(Schwedische Südpolar-Expedition, Stockholm 1912, 74 pp., 3 pi.). 
This is a report on the Lichens brought back by the Swedish Ant¬ 
arctic Expedition which left Göteborg in 1901 and returned in 1904. 
The specimens were in an excellent state of preservation not a single 
specimen being attached by mould. There are 145 species of which 33 are 
described as new distributed among the genera Lecidia (5 spp.), Biatora 
(1 sp.), Bacidia (2 spp.), Thelotrema (1 sp.), Pertusaria \3 spp.), Pla- 
codiuvi (1 sp.), Caloplaca (1 sp.), Lecanora (2 spp.), Aspicilia (3 spp.), 
Pannopar?nelia (1 sp.), Parmelia (1 sp.), Rinodina (1 sp.), Buellia (5 spp.), 
Acarospora (1 sp.), Parmeliella (2 spp.) and Verrucaria (3 spp.). Most 
of the new species are illustrated by photographs. A parasite, Chaeto- 
mium Bacidiae is also described as new. Notes are added to the diagnoses. 
A systematic account of the species is given the locality and habitat 
being noted and a reference added giving the best available description 
of the species and also anything of interest with regard to its distribution. 
A list of the subantarctic South-American species is added excluding the 
Lichens of South Georgia, and also a complete systematic list of Antarctic 
Lichens, with an indication of the place of their occurrence. Under the 
heading of “Some geographical considerations” the author gives many 
interesting facts. The nine species published by Hooker in his Flora 
Antarctica are considered. A historical enumeration of the material and 
the new species brought back by the various Antarctic expeditions is given.
