This species is probably widely spread in the Antarctic. The Falkland 
Islands specimens agree well with Hooker's Kerguelen material in the 
Kew herbarium, and there can be no doubt but that it is the same plant. 
In Kerguelen it grew on bare boggy earth near the sea, and Mrs. Vallentin's 
specimens occurred on the roots and stems of Gunnera misandra at the 
margins of a lagoon, and were sometimes under water owing to heavy rains. 
L. kerguelensis is closely allied to Ciliaria scutellata, Quél., with which it 
agrees in its aquatic tendencies, but it differs, as Berkeley originally stated, 
in its broader spores and larger size. It was also collected by Hooker at 
Cape Horn and has been recorded from New Zealand, but the Kew examples 
of Berggren's New Zealand specimens have decidedly larger spores. 
Ап enlarged and revised description based on Mrs. Vallentin’s drawings 
and formalin material is appended. 
Apothecia 1-1:5 cm., sessile, flattened, bright vermilion, beset with short, 
brown, pointed hairs. Excipulum rather thin, composed of large polygonal 
cells, bearing rhizoidal filaments and a few hairs below and passing into a 
subhymenial layer above, which is composed of loosely interwoven hyphæ 
10-15 ш diam. Marginal hairs brown, septate or almost aseptate, pointed, 
rather flaccid, 400-700 ш long. Рагарһухеѕ slender, septate, branched. 
apices clavate, 8-12 и thick. Asci rather long, cylindrical, 220-240 y long, 
18-20 y wide. Spores hyaline, smooth, granular, 17-22 x 13-17 y.

DisrriB. Probably cosmopolitan. 
Any doubt that there might have been as to the correctness of Berkeley's 
Falkland Islands record is placed beyond dispute by the present material. 
It agrees precisely with British specimens and also with Boudier’s figure 
(L. с.), except that the asci are slightly longer. Spegazzini notes that the 
species is exceedingly common on cow- and horse-dung in Fuegia (87, 
p. 124).

DisrriB. Falkland Islands. 
Persoon described this plant as a Puffball, but an authentic fragment was 
examined by Léveillé, who found asci present and referred it to the genus
