different media with Phyllosticta pinna, and they find that the form of 
the spores varies with the medium used in cultivation. Thus the 
normally colourless simple spores of P. pirina may become septate and 
slightly coloured, and finally there may be produced a macrosporoid 
form with coloured spores similar to those of Macrosporium. A. L. S. 
Fungus Present in Pellia epiphylla. — W. F. F. Rldler (Ann. 
Bot ., 1922, 37, 193-207, 8 figs.). The cells of the thallus of Pellia 
epiphylla contain a fungus which occurs in a definite zone along the 
thickened median portion towards the ventral surface of the thallus, 
and in the rhizoids, also in proximity to the antheridia and archegonia. 
The fungus has been isolated and identified as a species of Phoma. 
The writer allows that the relationship between host and fungus may 
be a symbiotic one ; but the Phoma is probably the dominant partner 
and of little use to the Pellia , and in extreme cases it destroys the host.

Fungi from New Caledonia.— Elsie M. Wakefield (Journ. Linn. 
Soc ., 1922, 46, 88-93). The fungi were collected by R. H. Compton, 
and bear out a statement already made that the affinities ol the fungus- 
flora are chiefly with that of the tropics of the old world. There are 
thirty -three species listed, nine of which are new records for the island. 
The author describes two new species, Glavaria flahellata and Enccelia 
neo-caledonica. A. L. S. 
Quick Method of Determining the Colour of Spores. — Leon 
Azoulay (Bull. Soc. My col. France , 1921, 37, 146-8). It is often 
necessary to determine exactly the colour of spores in Agarics : the 
author explains his method of doing this in the field. He tears a piece 
of paper to give it an uneven edge, moistens it and passes it between 
the gills of the fungus. The spores adhere in masses and the colour 
shows up clearly. Other methods are to use a brush or a piece of damp 
cloth, etc. A. L. S. 
Dried Fungi in the Paris Market. — Martin-Claude (Bull. Soc. 
Mycol. France , 1921, 37, 148-9). The fungi in question, Boletus 
edulis , were offered for sale in thin slices dried in heated air. By soak- 
ing in water they regained their size and appearance, and were as 
pleasant to eat as those freshlj gathered. A. L. S. 
Boleti with Red Pores and Red Russulse.— P. Brebinaud (Bull. 
Soc. Mycol. France , 1921, 37, 149-55). The author contributes a series 
of observations on the colour of these fungi, on the changes that the 
colour may undergo, on the formation of the network of markings on 
the stalk, and on the underground mycelium. He gives suggestive notes 
on associations with earth-worms, etc. A. L. S. 
Mycological Notes. — C. Gf. Lloyd ( Cincinnati , Ohio, 1922, 7, 
1105-36, 16 pis.). 0. G. Lloyd gives photographs of W. A. Setchell 
and of the Japanese mycologist, A. Yasuda. He publishes short notes 
on a vast number of specimens received from every quarter of the 
globe. The forms under observation are illustrated by photographs 
(about 120 or more are reproduced), and give a vivid representation of 
the fungi dealt with, many of them rare forms. A. L. S.
