Kingdom Fungi Lecture Notes

This set of vocabulary flashcards covers the introduction, classification, structure, and reproduction of Kingdom Fungi, along with details on specific phyla and lichens as per the lecture notes.

Kingdom Fungi

A kingdom of heterotrophic, achlorophyllous eukaryotes that include organisms such as molds, chytrids, mildews, mushrooms, puffballs, smuts, and rusts.

Saprobes

Fungi that obtain their food from dead organic matter.

Symbionts

Organisms that exist together in a mutually beneficial relationship.

Chitin

A substance found in the cell walls of both unicellular and multicellular filamentous fungi.

Hyphae

The individual filaments that make up the body of a multicellular fungus.

Mycelium

The mass of individual filaments (hyphae) that forms the body of a fungus.

Fruiting Bodies

Structures produced by fungi that contain non-motile spores for asexual and sexual reproduction.

Phylum Chytridiomycota

Also known as chytrids, this phylum refers to the chytridium structure containing unreleased spores; members are often aquatic and have coenocytic thalli.

Zoospores

Motile spores produced by chytrids that possess flagella.

Phylum Zygomycota

Known as the zygospore fungi, they form spherical spores during sexual reproduction and are typically saprophytic with coenocytic hyphae.

Zygospores

Spherical spores formed during sexual reproduction in the Phylum Zygomycota.

Stolons

Horizontal, non-septate hyphae found in the Phylum Zygomycota, such as in the genus Rhizopus.

Sporangiophores

Erect hyphae that support the sporangia during asexual reproduction in Zygomycota.

Columella

A central sterile structure found within the sporangium of Rhizopus.

Phylum Ascomycota

Known as the sac fungi, they possess a distinct sac-like structure (ascus) that contains non-motile ascospores.

Ascus

A sac-like structure in Ascomycota that houses ascospores.

Budding

The asexual reproduction method observed in unicellular Ascomycota such as Saccharomyces (Yeast).

Conidia

Asexual spores produced by members of Phylum Ascomycota, including the genera Aspergillus and Penicillium.

Ascocarp

The sexual fruiting body of an Ascomycete fungus, such as the one found in the genus Peziza.

Tirmania

A genus of edible white-cream coloured truffles commonly referred to as 'Zubaidi'.

Terfesia

A genus of edible black-dark brown coloured truffles commonly referred to as 'Ikhlasi'.

Phylum Basidiomycota

Known as the club fungi, they reproduce sexually through specialized club-shaped end cells called basidia.

Basidia

Specialized club-shaped end cells in Basidiomycota where basidiospores are produced.

Pileus

The cap part of a mushroom's basidiocarp, found in genera like Agaricus and Coprinus.

Stipe

The stalk or stem-like structure of a mushroom's fruiting body.

Annulus

A ring-like structure found on the stipe of certain mushrooms like Agaricus.

Phylum Deuteromycota

Referred to as the 'imperfect fungi,' this non-natural group includes species that reproduce asexually and are members of Ascomycota or Basidiomycota.

Lichens

Symbiotic associations between a fungus (mycobiont) and an alga or cyanobacteria (phycobiont).

Mycobiont

The fungal partner in a lichen, which is from the Phylum Ascomycota in 98% of cases.

Phycobiont

The algal or cyanobacterial partner in a lichen that produces carbohydrates by photosynthesis.

Crustose

A lichen growth form characterized by a crust-like appearance on surfaces like rocks or tree trunks.

Foliose

A lichen growth form characterized by a leaf-like appearance.

Fruticose

A lichen growth form characterized by a bushy or bush-like appearance.
