XII. THE TRICHOLOMAS. 
The genus T'richoloma is known by its stout, fleshy stem, des- 
titute of a collar, and by its gills being attached to the stem, and 
having a shallow excavation or notch in the edge at or near the 
inner extremity. The species are numerous, and grow in woods 
and in fields or open places. Opportunity has been afforded for 
the trial of only a few of them. The following table may aid in 
finding the description of the species here discussed: 
Cap viscid, 1. 
Cap not viscid, dry or moist, 2. 
1. Cap yellowish, gills yellow, T. equestre 
1. Cap reddish-brown, gills not yellow, T. transmutans 
2. Cap reddish-brown, gills when old more or 
less spotted with dull red, T. wmbricatum 
2. Cap grayish-brown or blackish-brown, cov- 
ered with hairy fibrils or scaly, T. terreum 
2. Cap smooth, commonly grayish-violaceous, 
T. personatum 
The Equestrian tricholoma, T'richoloma equestre, is easily 
recognized by its sticky viscid cap of a yellowish color, and by its 
bright sulphur-colored or canary-yellow gills. The cap is firm 
and smooth, or sometimes with a slightly scaly appearance in the 
centre, where it is also usually tinged with dingy reddish or red- 
dish-brown hues, the yellow being more clear and distinct to- 
ward the margin. The flesh is white, and has a farinaceous 
taste, though no marked odor. The gills are a beautiful pale 
yellow, and on this account they have suggested to an esteemed 
correspondent the name “Canary mushroom,” which he applies 
to this species. They are closely placed side by side, and deeply 
notched or rounded at the extremity next the stem. The stem 
is short, stout and solid, and is either white or yellowish. 
The cap is two to four inches broad and is sometimes irregu- 
lar, the margin being wavy or some parts more elevated than 
others. The stem is commonly one to two inches long and one- 
third to two-thirds of an inch thick. With us it is more often 
white than yellow. The Equestrian mushroom or “Fir-tree 
tricholoma,” as it has been called by one writer, grows in or near 
pine woods and groves. It is especially to be found among
