It is regarded as poisonous.

Sulphury Mushroom. [Fig. 23.]

(Agaricus [Tricholoma] sulfureus.)55.

In woody places at the south of London this very disagreeable but handsome species now and then puts in an appearance. It has a particularly nasty penetrating smell, which has been compared with “gas-tar.” The stem is firm, as is the whole plant, and sulphur-coloured.

It is probably a very dangerous species, but I have seldom met with it.

Incrusted Mushroom. [Fig. 24.]

(Agaricus [Hebelonia] crustuliniformis.)278.

Growing in woods, this deleterious species is extremely common, and without doubt very dangerous. The dirty pale-umber gills, and its habitat and time of growth—viz. the autumn—at once distinguish it from the delicious A. gambosus, [fig. 19, Edible Sheet]. It has a powerful and highly disagreeable odour, and brown spores, and we believe it is often mistaken by the ignorant for the true mushroom.
