Key to Gasteromycetes and Ascomycetes.

Section A. Fungi that have the spores inside the cap. (Stomach fungi or Gasteromycetes.)

Section B. Fungi that have the spores in delicate sacs. (Spore sac fungi or Ascomycetes.)

SECTION A.
1.Fungi covered with a hard rind,Scleroderma.
2. In which the spores when ripe turn to dust,4.
Where spores are at first closed in a cup-like sac that resembles a bird’s-nest,3.
3. Fungi with the outside covering bowl-shaped of one cottony layer, Crucibulum, the Crucible.
Outside covering tubular, trumpet-shaped, of 3 layers, Cyathus, the cup.
Outside covering opening with a torn mouth, Nidularia, bird’s-nest.
4. Outer covering splitting into star-like points, Geaster, earth star.
Outer covering opening by a single mouth at the top, Lycoperdon, puff-ball.
Spores at first borne in an egg-like sac, when ripe elevated on a cap at the top of the stem, no veil, has an odious smell, Phallus, stink-horn fungus.
SECTION B.
1. Where the sacs soon become free, no special covering, mostly fleshy, cup-like fungi, Peziza, cup fungus.
Sacs opening from the first, caps pitted or furrowed,2.
2.Cap lobed, irregular, saddle-shaped, Helvella, yellowish fungus.
Cap oval or conical, upper surface with deep pits formed by long ridges, Morchella or Morel, honey-combed fungus.

(The genera described under Section B. all belong to the order of Discomycetes, fungi that have the spore sacs collected in a flattened disc.)
