Mushrooms with surface spores.
In my classification this section contains fungi with the spore bearing layer or hymenium on their external surfaces.
They have no gills or pores.
In this group I have included the club and coral fungi, some crusts, jelly fungi, stinkhorns and tooth fungi.
Variations in the hymenium include:
- Smooth hymenium. These are difficult to identify and require microscopy.
- Hydnoid fungi with the spores forming on teeth or spines.
- Merulioid fungi with a wrinkled hymenium.
- Stereoid fungi are crusts that form small caps (effused-reflexed) and most of these are species of Stereum and Steccherinum.
