Stature types[adopted from Largent, 1986]
There are seven characters that are utilized in determining the stature type of a mushroom.
Free or Finely Adnexed Gills:
The type of stipe differentiates the next two groups of four stature
types each. In the past, size was used to differentiate fibrous from
cartilaginous, but it worked only about 75% of the time. Fibrous stalks
were >4mm diameter.
Fibrous, or fleshy fibrous stipes are generally relatively thick.
When broken it will leave a "ragged edge". A cartilaginous stipe
is usually thinner and "breaks with a firm split when bent in two,
similar to cartilage (Largent, 1986)."
Attached Gills and a Central, Fleshy-Fibrous or Brittle Stalk, no volva
The next four stature types are usually rather small mushrooms with a
cartilaginous stipe and variously attached gills. None have a volva.
They are differentiated mostly by shape of the pileus, nature of the
pileal margin and gill attachment. Only one has an annulus.
The last stature type is completely artificial. All twelve of the
previous stature types have a (more or less) echocentral attachment of
1. Largent must have changed his mind about using the word Anellariod. That stature type appears as Galerinoid on page 63.
