'Mushrooms', as defined here, are a phylogenetically diverse
group all sharing the feature of having spores formed on gills on the underside
of a fleshy fruiting body.
Ecologically they are diverse, but most play important roles in nutrient
capture and nutrient flow within ecosystems. Some form mycorrhizas with
vascular plants, other are saprobes, helping to break down complex molecules
into forms more readily available as nutrient to other organisms. A few are
There are a series of 'mushroom' groups. Most genera belong in more than one of
these groups. For example there is a "Mushrooms with Brown Spores" Group which
also belongs in the "Mushrooms on Wood" Group.
