102 Algae. — Eum5'^cetes. 



geological character of a district and the constituents of its Alga- 

 flora, more especialh^ of its Desmid-flora. The entire Lake District 

 is an Older Palaeozoic area, in which a northern outcrop of Ordo- 

 vician strata is separated from a southern Silurian outcrop by an 

 extensive mass of pre-Devonian igneous material. The really rieh 

 Alga-floras are all on the Older Palaeozoic or Precambrian areas, 

 and the English Lake District possesses a richer Alga-flora than any 

 other part of England, although not quite equal to that of the 

 north-west of Scotland or the west of Ireland. The phytoplankton 

 of the lakes is similarly rieh in species, although not so prolific as 

 the limnetic flora of the lakes of north-west Scotland. 



Eighteen lakes were examined for their plankton, and of these, 

 thirteen are dealt with in the second part of the present paper. A 

 continuation will be published later. E. S. Gepp.

About 120 species of fungi are enumerated, chiefly parasites as 

 also their hostplants and their localities. Most interesting is the dis- 

 covery of the Boreal-Alpine Taphrina carnea Johans.

The author gives a general summary of what is known of this 

 subject. After an historical sketch a more detailed account of recent 

 work is given especially as to the author's own researches on Len- 

 tinus lepideiis, and Polyporus squamosus. The article concludes with 

 a brief account of the various processes employed for timber pre- 

 servation. A. D. Cotton.

The list published in the first part of the paper contains' the 

 names of 30 species of the larger fungi and 7 species of Mycetozoa. One 

 novelty is described viz. Cyphella Cheesmani Massee, a small white 

 species with ovoid, asperulate spores 12-15X7 — 8 |U. In part II the 

 coprophilous species are recorded. On düng brought to England 

 from Livingstone Island, Victoria Falls a number of fungi 

 developed, including 9 species of the family Sovdariae, and a new 

 species of Coprinus allied to C. radiatus, but larger in all its parts. 

 The plant is named by Gibbs C. Cheesinani. A. D. Cotton.

In 1901 — 2 the author was travelling in Bolivia and Argentine 

 to study the fungi, and reports have formerly been published con- 

 cerning other groups of fungi from his journey; here he gives a 

 report of the Gasteromycetes, of which he enumerates 27 species,
