SOME ENDOPHYTIC ALG.E. 295 
contains filaments which exactly correspond with those of 
Endoderma viride; the fruits have never been observed. 
N. laceratum, which is our commonest species of Nitophyllum, 
is rarely, if ever, attacked by Endoderma. Occasionally traces 
of Endoderma-like filaments have been observed, but they bear 
little resemblance to those of E. viride. The place of Endoderma 
on this plant is taken by a species of ALyrionema, from which 
it is seldom free. On the older portions of N. lacertum, Myrio- 
nema may often be found in fine fruit. 
Delesseria sinuosa.—The older parts of this plant are frequently 
infected, but not to a great extent. Fruits sometimes present. 
In D. sanguinea, Endoderma has not been detected. 
STREBLONEMA, 
STREBLONEMA INTESTINUM, Holmes d Batters, was first 
described by Reinsch under the name of Entonema intestinum (8). 
His specimens were found in Brongniartella byssoides at Wey- 
mouth, England, some of which are in the Kew Herbarium, 
named and presented by himself. Reinsch’s description is brief 
and the figures, if compared with his specimens, are very mis- 
leading. As neither a good description nor figure exists, and as 
part of the original specimens are preserved at Kew, it has been 
thought advisable to redeseribe it. 
Entonema intestinum was removed to the genus Streblonema 
by Holmes & Batters in the Appendix to British Marine Algæ 
(9. p. 525). The authors do not state their reasons for so doing, 
neither do they redescribe the plant, the original name is also 
not mentioned.* Batters, however, in his catalogue of British 
Marine Algæ (10. p. 29) mentions the older name and Reinsch’s 
locality. Apparently the plant has not been recorded since by 
any investigator. 
The following notes are based entirely on Reinsch’s pre- 
parations. 
Tbe thallus is formed of a system of filaments which are 
found between the cells of the host. There are no signs of 
external hairs. The filaments branch freely, alternately or 
irregularly, elongation takes place by apical growth, and 
bifurcation is not uncommon. The cells of the filaments 
average 10 pin thickness and 20 p in length. In the purely 
* I have Mr. Holmes's authority for stating that the alteration was b. 
ased 
upon the examination of Reinsch’s specimens at Kew.
