SOME ENDOPHYTIC ALGJE. 289 
and also every facility for study and research in the Laboratory 
of the Marine Biological Association at Plymouth. 
For ascertaining the range of species invaded by the endo- 
phytes, dried specimens have been examined, and, in the case of 
Endoderma, these answered well. The large collections of dried 
Alge at Kew were most valuable for this purpose. 
ENDODERMA. 
The species of Endoderma examined was that occurring in 
various Nitophyllez, generally accepted as Æ. viride, Lagerh.; 
it was first described by Reinke (1) and found by him in 
Derbesia Lamourouxii. Its appearance in Nitophyllum is some- 
what different to that in Derbesia. Reinke moreover did not 
succeed in discovering the fruits. In one species of Nitophyllum, 
viz. N. Hillie, Endoderma presents a constant and definite 
appearance, and in the right season the fruits are particularly 
abundant. Algologists will find this host useful for the exami- 
nation of a definite form of E. viride, and one which almost 
always provides the material required. It is also tolerably well 
suited for artificial eultures. 
Huber, 1882, in his admirable monograph of the endophytic 
Chætophoreæ (2), brings together in a useful way the various 
endophytic genera of the Chlorophyces. He gives a detailed 
account of the genera and species, and full references will be 
found in his paper to literature published previous to 1882. 
Amongst other genera there mentioned is Endoderma, which he 
divides into two sections: Eetocheta, those species possessing 
external hairs; and Zntocladia, those without these structures. 
E. viride was not examined by Huber, though he gives it a place 
in the latter section. 
Reinke, in first describing the endophyte in Derbesia, named 
it Entocladia viride; he was unable to describe the fruits, but 
surmised that the affinity of the plant would be with Stiyeo- 
clonium. His fig. 8 rather suggests a young sporangium, and 
Reinke himself draws attention to the possibility of this, but he 
leaves the question undecided. Wille (3), in 1880, described 
the fruit for the first time in a form occurring in species of 
Ectocarpus, and named the plant Entocladia Wittrockii, 
Lagerheim (4), in 1883, replaced Reinke’s generic name Ento- 
cladia by that of Endoderma.
