Stature types[adopted from Largent, 1986]There are seven characters that are utilized in determining the stature type of a mushroom. They are:
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 the stipe. 1. Largent must have changed his mind about using the word Anellariod. That stature type appears as Galerinoid on page 63. |
