Rock, Sidmouth, sh — a a tomentosum which had a 
very peculiar appearance ; on ex ing them with the microscope 
I found that they had | een ‘itackod = this weiiotis little epiphyte. 
In general appearance the plant might pass for Microcoleus chthono- 
plastes, from which it can instantly be distinguished by the numerous 
heterocysts, the pseudo-branching of the trichomes, and the curious 
manner in which they are coiled and twisted within the sheath.

gathered in September, 1897, a oo I noticed that "tikes 
specimens were covered with small dark green swellings, but I did 
not examine them at the time. Subsequently I found at Sidmouth 
similar specimens, which, upon examination, proved to be the 
above-named species mixed with a brown crustaceous alga, which 
may turn out to be Lithoderma Kjelimani, but in the absence of 
spores I cannot identify the plant with certainty.

Mr, Buffham, which I obtained on his death, is a specimen of a 
Ulothrix, which must certainly be referred to this species. In every 
way it corresponds with the figures and desc Pe given by Wille,

I found this species (bearing sporangia, though sparingly) in the 
caves near the Picket tak. Sidmouth, in the autumn of 1901, and _

in the caves at Dodd’s Well, Berwick- on-T weed 
It forms a thin widely-expanded yellowish- fies ‘crust on the 
sides of the caves, from which it can be cut with a knife in patches 
of considerable size. I had hoped to find Ectocarpus Seahiies Kuck 
mixed with it, but in this zi I was disappoi nted,
