Phylum Basiciomycota

Club fungi

Imperfect Fungi

Asexual reproduction only (penicillium and Aspergillus)

Lichens

Symbiotic relationship of a photosynthetic organisms and a fungus

Mycobiont

Fungal component of lichen

Photobiont

photosynthetic component of lichen

Mutualism

relationship where both parties benefit

Crustose

Lichen resembling crust

Foliose

Lichen resembling leaves

Fruticose

Lichen resembling bushes

Gibberellins (GA)

group of plant hormones that stimulate stem __elongation__, __germination__, and __flowering__

Etiolation

stem elongation poor leaf development lack of chlorophyll due to growth in dark

Chitin

Strong and flexible polysaccharides; makes up fungal cell walls

Heterotrophic

Gaining nutrients from organic compounds

Hyphae

Network of tiny connected filaments that allow fungi to branch out and collect nutrients

Mycelium

Collection hyphae, what infiltrates organisms and substances; maximizes surface area to volume ratio

Perfect Fungi

Fungi that reproduce through sexual reproduction

Plasmogamy

first half of syngamy; cell membranes and cytoplasm fuse

Karyogamy

second half of syngamy; nuclei fuse

Ascus

sac-like sporangium

Basidium

Reproductive appendage of Basidiomycetes; located on the gills of the fruiting body

Cap (pileus)

the top part of a mushroom

Stripe (Stalk)

supports the cap and the gills and can be separated from the other parts

Gills (Lamella)

a papery hymenophore rib under the cap of some mushroom species

Ring (annulus)

ring-like or collar-like structure sometimes found on the stipe of some species of mushrooms
