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.
