tinguishable, unless one decides by colour alone taking inversa to

Clitocybe Sadleri Berk. (Cooke “Illus” pl. 127) is nothing but a 
distorted form of H. fasciculare as its caspitose habit, its colour and 
its acrid bitter taste show. It is one of the peculiarities of A. fascz- 
culare that it often fails to produce spores on its hymenium so that 
the gills remain sulphur yellow. One or two such specimens 
generally turn up at each fungus show. I have several times seen it 
in this condition at Hereford, as well as at Selby and /Vorksop, It 
does not seem that the spores are deficient in colour, but that they 
are not produced at all. | 
There are three Collybie either growing upon fir cones or 
under fir trees, both Spruce and Scotch, which are very difficult to 
differentiate, viz. Collybia tenacella Jacq., esculenta Pers., and conigena 
Pers. They are all common, and occur all the year round; but 
personally I must admit my inability to discriminate them and would 
recommend their special study to the members of the Mycological 
Society. It may be that they are three good species, or it may be 
that there are only two. 
Mycena Iris Berk. a by no means uncommon, but frequently 
overlooked Mycena, since the blue fibrilla disappear almost as soon as 
the plant is above the ground level. ‘They are seen to the best 
advantage on those young specimens which are coming up amongst 
fir needles. Ifa handful of the loose needles be gathered in which 
a very ordinary looking pale brownish Mycena is growing, and the 
bases of the stems examined, young plants with the blue fibrilla may 
generally be found. ‘There is no really good figure of this fungus: 
Berkeley’s “ Outlines,” t. 6 fig. 3 is perhaps the best. Cooke III. plate 
161, lower fig., is from Berkeley’s original sketch. Bresadola’s A4Zycena 
calorhiza, t. 5 fig. 1, is the same plant. 
This last named plate is grotesquely over-coloured, an error into 
which those who paint fungi with water colours do not generally 
fall. ‘his mistake is usually in the opposite direction—not getting 
the tint dark enough. There are two pink-spored species which it 
is hardly possible to depict in sufficiently brilliant colours, viz., 
Pluteus leoninus Schaef. and Leptonia euchroa Pers. The figures 
in the “Illustrations” (421 and 334) convey but a very inadequate 
idea of the brightness of the colouration, either of the orange or 
of the blue; and if you try to figure them yourselves you will find 
that your colour box does not contain pigments of sufficient 
brightness.
