Main fungal groups

Morphogroups illustrated


1. Basidiomycota

Agarics – have gills and usually fleshy

Chanterelles – have shallow gill folds and are fleshy

Boletes and polypores – fleshy boletes and tough polypores both have tubes (opening by pores)

Tooth Fungi – have downward pointing teeth or spines and vary in texture from fleshy to leathery, with or without a cap

Leathers – are leathery in texture and the spore-bearing surface is smooth or only a little wrinkled

Corals – are fleshy with spores formed on the entire surface of the upper part of a club-like or coral-like fruit-body. The clubs usually grow upwards, but occasionally hang downwards

Jellies – have a jelly-like or gelatinous texture, and come in various shapes such as brain-like. Spores are formed on the outside surface of the fruit-body or on spines under a shelf-like cap. Colours are often bright orange or yellow, but also white.

Rusts – are parasites which grow only on living plants, forming tiny disc-shaped yellow or orange spore masses. They have a special stage in their life-cycle called the cluster cup (aecium) which is a shallowly to deeply cylindrical fruit-body with spores formed at the base of the interior of the cylinder.

Earthstars – have an outer layer to their spore sac that splits into rays and the spores are liberated through the mouth (stoma)

Stalked Puffballs – have a distinct stem supporting the head which contains the spore mass

Stinkhorns – are initially completely covered by a membrane colloquially called an egg. The egg breaks to reveal a fruit-body which is phallic, cage-like or with arms. The spore mass is slimy and often foul-smelling and covers the inner surface of the cage, arms, egg or head when the fruit-body is phallic. In phallic stinkhorns an indusium may hang from the head, like a lacy net.


2. Ascomycota

Beech Oranges – rounded orange fruit-bodies with large pits

Morels – honey-comb-like head on a stem

Cups – a common form of Ascomycota with spores formed on the inside surface of a shallow to deep cup which may have a stem

Clubs – are club-shaped with a stem not much narrower than the head. This group can look very similar to the corals but are not as fleshy as the corals.

Crusts – form thick, thin or lobed fruit-bodies which lie directly on the substrate

Discs – are disc-like with a flat upper surface which is where the spores are formed

Pins – have a pin-shaped fruit-body with a definite head and narrower stem


3.  Myxomycetes – plasmodial or acellular slime moulds

Myxomycetes belong to a different Kingdom from fungi but they are studied by mycologists, are covered by the same nomenclatural code and often appear together.

Dictyostelids – cellular slime moulds

Protostelids

Plasmodial slime moulds – appear on rotting logs, stumps or live vegetation during summer, first as moist, bright yellow amorphous blobs
