Collybia

But in the case of most species of _Amanita_, certain species of _Lepiota_, _Collybia_, etc., a trowel is necessary to get up the base of the plant in such a way as to preserve essential characters.

The plants are usually smaller, many of them being of small size, the cap is usually bell-shaped, rarely umbilicate, but what is a more important character the margin of the cap in the young stage is straight as it is applied against the stem, and not at first incurved as it is in _Collybia_, when the gills and margin of the pileus lie against the stem.

OMPHALIA Fr. The genus _Omphalia_ is closely related to _Mycena_ and _Collybia_.

= -- This is a much larger and stouter plant than _Collybia radicata_, though it is not so tall as the larger specimens of that species.

In many genera, as _Collybia_, _Mycena_, _Omphalia_, etc., the pileus simply expands without having its margin ever united to the stipe by any special structure, but in other forms, which include by far the greater number of genera of the _Agaricaceæ_ and some _Boleti_, the interval between the stem and pileus is bridged over by threads growing from the margin of the pileus and from the outer layers of the stem.
