Notes on Fungi. 351 



red and flesh, colour, may be cited because, in the character of 

 the stem, it approaches Gollybia, though the pileus and gills 

 are quite those of the truest Tricholoma, as will be seen by the 

 subjoined figure (Fig. 3). 



Glitocybe, a name derived from kXitos, a sloping, and Kuftr), 

 a head, is the designation of the next subgenus. It is closely 

 allied to Tricholoma, but is distinguished by the gills not being 

 sinuated behind, but regularly attenuated and running down 

 the stem. Few of the species are eaten ; but Agaricus nebularis 

 and geotropus, or, at least, that form of the latter which is 

 figured by Batsch, under the name of A. subinvolutus, of which 

 we give a reduced figure, are excellent (Fig. 4) . We have par- 

 taken of the common form, under the auspices of Dr. Badham, 

 but did not consider it good, though, like several other species 

 of the subgenus, it is wholesome. 



The species are often rather difficult of determination, as 

 the differences are less striking than in most other subgenera. 

 The main divisions consist of — (1), those with an obtuse pileus, 

 like A. nebularis, which at length becomes more or less plane ; 

 (2), species with an irregular, often sub-oblique pileus, with 

 unequally decurrent gills; (3), those which, though at first 

 umbonate, become at length entirely infundibuliform, with long 

 and equally decurrent gills. In all these the pileus is not 

 hygrophanous as in the three following — (4), species with a 

 thin, almost membranous, cup-shaped pileus ; (5), those, on 

 the contrary, which are subcarnose, convex at first, then plane 

 or depressed, with the gills adnate, or only very shortly 

 decurrent; while (6) the last has again a thin pileus, which 

 is often scaly or perfuraceous. 



In the first section, besides A. nebularis already mentioned, 

 which is conspicuous amongst leaves in woods for its pale 

 cinereous, somewhat pruinose pileus and elastic fibrnlose 

 stem, and which is very highly esteemed as an esculent, 

 one of the most remarkable is the greenish A. odorus, not 

 uncommon in woods, which diffuses a strong scent of aniseed. 

 In the second, A. fumosus, which sometimes forms dense tufts, 

 is one of our best known species. In the third, we have A. 

 giganteus and maximus, which acquire a diameter of a foot or 

 more, and the latter of which forms sometimes rings in woods 

 many feet across, besides which there are many allied British 

 species, some of which are extremely common. In the fourth 

 section, one of the most common towards the end of autumn 

 is A. cyathiformis, its brown, cup-shaped, hygrophanous pilei 

 being conspicuous both in woods and pastures ; in the fifth, 

 A. fragrans will obtrude itself on notice by its fragrance, 

 resembling that of A. odorus, though its form and colour are 

 different ; while in the sixth, we have the commonest of all
