Leocarpus fragilis – Slime mould

adnate –refers to fills/pores/wrinkles/teeth, broadly attached to top of stem

adnexed– refers to gills/pores/wrinkles/teeth, partially attached to top of stem

Agaric– the word often used synonymously with ‘mushroom’ – a fungus that produces spores on gills.

anastomosing – cross connections between gills

annulus-a remnant of the partial veil left as the mushroom matures. It often leaves a ring of membranous tissue around the stem (stipe)

Ascomycota – funga with sexual spores borne in a flask-shaped structure called an ascus

ascus –microscopic flask-like structure containing sexual spores of Ascomycota

basal disc – disc-like structure at the base of the stem, as in Pixie’s Parasol

Basidiomycota– fungi with sexual spores borne on the outside of a special club-shaped structure called a basidium

basidium microscopic club-like structure with prongs on which are sexual spores.

bifid – divided into two

Bolete– soft textured fungi which generally have pores instead of gills

bracket – pored fungus with a bracket-shaped sporing-body on trees or dead wood. A similar shaped sporing-body without pores is referred to as either a shelf or a fan

bryophyte – a collective name for mosses, liverworts and hornworts

bulbous– a bulb-like swelling at the base of the stem (stipe), often underground

button –immature specimen

caespitose – with fruit-bodies growing in a dense clump

cap– pileus which is the umbrella or bell-like ‘hat’ of the mushroom. The pileus holds the spores in either gills or pores, wrinkles or teeth

carpophore –complete fruit body of the fungus (ie. cap, stem, gills, etc). Sporophore and sporocarp are other names also used

clavate – club-shaped

close – refers to gill spacing; neither crowded nor distant

cluster cup – cylindrical fruit-body of one of the stages in the live cycle of rusts

concentric – with circular or arc-like zones or bands having a common centre

convex – of caps, rounded or domed

convoluted – wrinkled, brain-like, intricately folded

coprophilous – growing on dung

cortina – cobweb-like partial veil

crowded – refers to gill spacing, very close together

decurrent – refers to gills/pores/wrinkles/teeth whose attachment to the stem extends down for some distance

cup –description given to the saucer shape of the Ascomycetes group

deliquescent – liquefying at maturity, common among Ink-caps

depressed – of caps, sunk in the centre like a saucer

distant – refers to gills, widely spaced

downy – with soft, fluffy hairs

egg – initial egg-shaped stage of some fungi which have a universal veil covering the developing cap and stem (stinkhorns, amanitas, puffballs)

endoperidium – inner layer of a multilayered perineum, covering the spore mass

exoperidium – typically of earthstars and stalked puffballs, outer layer of a multilayered peridium

face –side of a gill

family – a group of closely related genera, the name ending in -aceae

fan – a bracket-shaped sporing body with gills on the underside of the cap

fertile surface – surface bearing spores such as the surface covering gills or spines

fetid – foul-smelling

fibrillose – covered with fine, silky fibres which are usually appressed, i.e. pressed flat to the surface

forked – usually refers to gills, divided or pronged like a fork

free – refers to gills/pores/wrinkles/teeth, not attached to stem

fruit-body or sporing body – the visible, reproductive structure of any fungus

fungus (pl. funga) – a member of the Kingdom Funga; organisms which typically are composed of hyphae, reproduce by spores and possess nuclei, and which lack roots, leaves and chlorophyll (to carry out photosynthesis)

gelatinous – jelly-like

genus (pl. genera) – a group of closely related species

gill (lamina) – blade-like or leaf-like plate on which spores are produced, beneath the cap of an agaric

genus –taxonomic term meaning a group of similar species. Genera that are closely related are placed into families

gill– spore-bearing structure of mushrooms

gleba – see spore mass

globe–the spore mass inside a puffball

gluten – clear, jelly-like, sticky liquid exuded by some fungi

gregarious – with many fruit-bodies growing close to one another

habit – manner of growth of fruit-body, whether single, gregarious or clustered (caespitose)

habitat – the vegetation, soil and any other distinctive components of the place where the fungus naturally occurs

head – refers to fungi without caps, the part of the fruit-body supported on a stem

hygrophanous – changing colour upon drying

hygroscopic – sensitive to moisture

hypha (pl. hyphae) – microscopic, tubular filamentous units of a fungus

hypha –a microscopic fibre making up the fungal body.

incurved – of cap margin, turned under towards stem

indusium – in some stinkhorns, net-like veil which hangs down like a skirt

ink cap– common name of the Coprinus genus– the caps turn to an inky mess when picked and before you can dry them!

inrolled – of cap margin, turned under towards stem

inturned – of cap margin, slightly incurved

lamella (pl. lamellae) – see gill

lateral – of stems, attached at side of cap

lobed – with rounded projections

look-alikes – species that look superficially similar to the species being described

luminescent – glowing in the dark

margin– typically of cap or fills, outer edge

membranous – typically of ring, like a membrane or skin

mesoperidium – typically of stalked puffballs, the middle layer of a three-layered peridium

milk– a liquid exuded from certain species such as Lactarius deliciosus

mouth – opening through which spores are discharged

mushroom – fungus with gills on the underside of the cap, usually with a stem; generally refers to an agaric

mycelial disc – disc-like structure found at base of stem, consisting of a compact mass of mycelium

mycelium– vegetative part of the fungus which grows in the host or soil and produces the fruit body; the mycelium is like a mass of often microscopic fibres

mycorrhiza– the association between the mycelium of a fungus and the rootlets of plants. Little is known of the associations between fungi and plants in Australia; hence, the important questions on habitat and nearest tree/plant in the mapping scheme

odour– smell of the sporing-body

partial veil– covering of the gills while very young that breaks open, often leaving remnants on the stem (stipe)

Polypores common name of tough-textured funga with pores

pileus– cap

species– group of individuals with certain common characteristics

spore– microscopic part of the fungus, which can germinate to reproduce the fungus

spore print– spore material left on paper when the cap is left for a period of time — the colour can be an important identifying characteristic

stipe– stalk or stem of the fruiting body of the fungus

universal veil– material, which completely covers the young immature mushroom

volva – the remnant of the universal veil which is sometimes left at the base of the stipe
