General characteristics

* The fruiting bodies mostly have a central stipe. Some are medium-sized and there are also smaller species. The caps range in colour from yellow/brown to brick red. * The spore colour is dark brown to black. * The cap is smooth. * The developing mushroom is enveloped in a veil, but in ''Hypholoma'' this can be seen only in very young examples. This means that there is no well-defined ring, and nor are there distinctive flakes on the cap, but there may be cottony ring zones on the stipe, sometimes coloured by the dark spores. * The genus is widespread throughout the world and its best known representatives grow on dead wood, whilst some others grow in moss, sometimes on
moors The term Moor, derived from the ancient Mauri, is an exonym first used by Christian Europeans to designate the Muslim inhabitants of the Maghreb, the Iberian Peninsula, Sicily and Malta during the Middle Ages. Moors are not a distinct or ...
