tober, and unilocular sporangia in March, May, June, July, October 
and November, so it is doubtless able to fructify all the year round. 
This species is extremely common along the coasts of the Faeroes 
and was already reported by Lyngbye, 1. c. Var. opposita is the most 
commonly distributed; var. firma is rarer, and var. varia I found once 
only near Kvivig. 
Conferva ferruginea Lyngb., Hydrophyt., p. 159, tab. 55 C, 
belongs to this species, as may be distinctly seen from Lyngbye’s 
figure. In Lyngbye’s Herbarium in Copenhagen there are no spe¬ 
cimens labelled in Lyngbye’s handwriting, but one on which is 
written in Liebmann’s handwriting: »Conferva ferruginea Lyngb. 
ad rup. marit. Nsess.« It is, however, undoubtedly one of Lyngbye’s 
specimens, as the habitat corresponds to that given by Lyngbye 
in Hydrophyt. On examining this specimen it also proved to be 
like E.litoralis. In Hydrophyt. Lyngbye says: »Habitat ad insulas 
Fseroenses, rupibus maritimis abruptis in summo refluxus limite 
adhaerescens, ut ad Nses Osteroe et ad Hoyvig prope Thorshavn«.

97. I. sphaerophora (Harv.) Kjellm., N. I., p. 341 (276); Reinke, 
Atlas, pi. 30. 
Found as an epiphyte on, e. g. Ceramium acanthonotum , Calli- 
thamnion Arbuscula and C. scopnlorum, Gigartina mamillosa, Clado- 
phora rupestris and other algae growing in the littoral zone on ex¬ 
posed coasts, also — though rarely — in sheltered situations. Near 
Molen on Ostero it occurred at the mouth of a stream, closely 
overgrown with Diatoms. Unilocular sporangia were observed in 
May and June. 
Found in the following places: — Ost.: Molen (!); Str.: Kvivig (!), 
.Velbestad (!), Arge (!), in Sundene between Kvalvig and Thorsvig (!); 
St. Dimon: at the landing-place (!); Syd.: Frodebo (!). 
Order MYRIONEMACEAE.

98. M. globosum (Reinke) Sauvageau, Sur quelques Myrionemacees, 
Extrait des Ann. d. sc. nat., Bot., 8 ser., t.5, 1897, pp.9—14; Ascocyclus 
globosus Reinke, Atlas deutsch. Meeresalg., p. 20, pi. 17; Phycocelis 
globosus Rosenv:, Deuxieme Mem. sur les Alg. mar. du Groenl., p. 86. 
To this species I have referred a small alga which occurred 
as small, semiglobular cushions, or, where the latter merged into 
Botany of the Faeroes.
