Lec7 Flashcards
Agaricus is a genus of mushrooms containing only edible species.
T/F?
F, both edible and poisonous species.
Mushrooms are rich in the antioxidant called
selenium
edible if collected early, before fertile layers are formed.
Coprinus comatus
not toxic but considered non-edible due to their fibrous texture
Geastrum
Why Pucciniomycotina called Lower Basidiomycetes?
because they do not produce Basidiocarps.
All individuals are mono-parasitizing
In Pucciniomycotina
is a microscopic sporangium (or sporeproducing structure) found on the hymenophore of fruiting bodies of basidiomycete fungi which are also called tertiary mycelium
Basidium
- are dioecious host, with wheat being the primary host while barberry plant is the secondary host.
- long-cycle ( 5 stages ).
- stem black, and cereal rusts.
Puccinia graminis tritici
- Some are only known from their anamorphs.
- are plant pathogens.
- rust fungi.
- mono-parasitizing.
Pucciniomycotina
- from the genus Hapalopilus have
caused poisoning in several people. - poroid fungi.
- Most are edible or at least nontoxic.
polyporus
- not toxic but considered non-edible.
- outer layer of the fruiting body splits
into segments. - known commonly as earthstars.
Geastrum
- Most species are edible
- smaller species ( pear-shaped )
Lycoperdon
- edible if collected early.
- short-lived, growing on straw, woody substrates and dung.
- Ink Caps.
Coprinus
Economic importance of the mushroom?
- antioxidants help protect the body from damaging free radicals that can cause conditions like heart disease and cancer.
- used for cancer, type 2 diabetes, high
cholesterol. - rich in Vitamin C and B complex.
greenish light at a wavelength of 520–530 nm. light emission is continuous and occurs only in living cells.
Bioluminescent fungi
universal veil ruptures and may remain as a cup, or volva, at the base of the stalk, or as warts or volval patches on the cap.

Delineation between edible and poisonous fungi is not clear-cut.
in which fungi?
mushrooms
“mushroom” have been derived from what?
the French word mousseron in reference to moss (mousse).
many small fingers like projection
Teeth
short, blunt elevated lines on stem and under cap
Ridges
many sma tubes ending in a spongy surface
pores
wide and thin sheet like plates radiating from stem
Gills
- Are filamentous fungi composed of hyphae.
- Some are obligate asexual reproducers.
Basidiomycota
specialized club-shaped end cells
basidia
