FUNGI- EUKARYOTES

Rozellomyceta

INCLUDES:

rozellomycota

• univellular might not be true funig

microsporidiomycota

• microsporidia

• spore-forming, unicellular parasites

CHYTRIDIOMYCOTA AND BLASTOCLADIOMYCOTA—Eumycota- fungi

Both groups are unique among eumycots for possessing motile zoospores

• led to them ebing classified as protists

• molecular DNA studies recover them as fungi

ZYgomycota- eumycota

• Parphyletic grouping including zoopagomyceta and mucoromyceta

• coenocyte-single cells contain multiple nuclei

• ex: black bread mold (rhizopud)

• — Like other fungi, reproduction involves spores

• Asexual and sexual reproduction

FUNGI: EUMYCOTA: Dikarya- ASCOMYCOTA

• Sac fungi: truffles, yeasts, morals, etc

• Hyphae are partioned into individual cylindrical cells 

• have asexual and sexual reproduction

ERGOT: TYPE OF ASCOMYCOTA

Ergot is a fungus that parasitizes rye

• it rarely seriously damages the rye, but when ingested by humans, it causes a disease calle ergotism

— can cause hysteria, convulsions, and sometimes death

— a common problem in the middle ages 

PENICILLIUM: TYPE OF ASCOMYCOTA

• FUNGUS THAT PRODUCES PENICILLIN

• PENICILLIN FIRST DISCOVERED IN 1929 BUT NOT UNDERSTOOD AND APPLIED UNTIL WORLD WAR II

EUMYCOTA: DIKARYA: BASIDIOMYCOTA

• CLUB FUNGI: mushrooms, stinkhorns, puffballs, msuts, shelf fungi, etc

• they produce spores at the tips of swollen hyphae called basidia

Basidiomycota diversity

• shelf fungi

• puffballs

• smut

INGESTING MUSHROOMS

• Some musrooms are deadly to humans

• some cause hallucinations

• most muschrooms have little nutritional value

• - exception: shiitake mushroom

MYCORRHIZAL FUNGI

• symbiotic interation between fungi and the roots of plants

• the plant provides food for the fungus via photosynthesis

• the fungus helps the plant take in water and nutrients from the soil especially phosphorus

• most plants have this mycorrhizal

LICHEN

A symbiotic relaitonship between algae and lichen

• algae supplies food

• fungus protextsm produces a substance that accelerates photosynthesis and absorbs and retains water and minerals

Able to live in hostile envionrments

3 growth forms:

• crutose

• foliose

• fructiose

mainy reproduce asexually

Crutose-lichen

attached/embedded over whole surface

foliose

leaf-like thalli with crinkly edges

Fruticose

hang down from branches
