The sequence of genera is that of Saccardo’s * Sylloge Fungorum, except 
that the Discomycetes immediately follow the Pyrenomycetes.

The genus is new to the Falklands, and, strangely enough, in the wooded 
district of Fuegia, where it might have been expected, it was neither found 
by Hariot nor Spegazzini. 
А. Robinsonii was originally described from material collected at Juan 
Fernandez, specimens of which exist at Kew. The diagnosis was scanty, 
but the plant has been recorded from many other parts of the world, 
including N. America, Africa, and Australia, its short growth and slender 
filaments marking it off from A. scoriadea, Scorias spongiosa, and other 
well-known southern forms. The genus Antennaria is badly in need of 
gx 
revision, and it is impossible to state the exact distribution of A. Robinsonii 
or the exact limits of the species. 
The original specimens, on leaves of a fern, show a creeping, torulose, non- 
punctate mycelium, consisting either of very short cells hardly longer than 
broad or of oblong cells measuring 15-18 x 6-8 р. Тһе same diversity 
is seen in the upright branches, though the majority are of the long-celled 
type. The rudiments of laterally-borne perithecia are visible, but these are 
too young to show spores. A few stouter filaments, consisting of barrel- 
shaped cells 15-18 и wide, are present. The Falkland Islands gathering, 
which are mostly on twigs and not on leaves, agrees well with this, but 
shows the velvety growth in better condition (perhaps owing to the moist 
climate), a fine pile of nearly black hyphae, composed of cells of greatly 
varying length (15-40 ш), extending over several inches. No fruits 
occur, but young stages of an Atichia (q. v.) are discernible amongst the 
filaments.

In the Falkland Islands, as elsewhere, this fungus frequently develops on 
herbarium specimens.

This peculiar gelatinous genus has until recently been so little known that
