- largest phylum of Fungi
- Some species are asexual
- form fruiting bodies around the asci (ascocarps)
- monophyletic group
- Several species are biological model
Ascomycota
1) Cleistothecium
2) Perithecium
3) Apothecium
4) Pseudothecium
This is type of what?
Type of Ascocarps
It is a unicellular fungus whose cell shape may be oval or spherical.
Saccharomyces
- found on the surface of plants and in sugar solutions
- Reproduction by producing endospores, binary fission, and sexual.
- some are grow on food and spoil it
Saccharomyces
yeast fungus multiplies by forming?
internal spore in unfavorable conditions
- found in various climates worldwide.
- defined as a group of conidial fungi, asexual state
- ability to grow where a high osmotic pressure exists
- highly aerobic.
Aspergillus
is a fungal genus within the Ascomycota and one of the more commonly observed species causes peach leaf curl.
Taphrina
- is a genus of fungi in the family Erysiphaceae.
- are plant pathogens which cause powdery mildew
- Symptoms are in the form of spots of white appearance
- sexually by forming spherical, black Cleistothecia, partially embedded in the mycelium
- asexually by forming conidia carriers
Erysiphe
- Ascospores are filamentous or needle shaped.
- causes Ergot disease on grassy
- disease is spread under cold weather
Claviceps
commonly known as the Cellar Cup is a species of Ascomycete fungus.
Peziza
Name means a sort of fungus without a root or stalk.
Peziza
- is obligate Saprophytic.
- upper surface of the fungus has a layer of cylindrical spore producing cells called asci.
Peziza
found growing on dead wood
Xylaria
Why Neurospora is widely used in genetics as a model organism ?
because it is quickly reproducing, is easy to culture and can survive on minimal media
- true morels.
- Is a genus of edible sac fungi closely related to anatomically simpler cup fungi in the order Pezizales.
- distinctive fungi have a honeycomb appearance due to the
network of ridges with pits composing their caps. - species are used to treat indigestion, phlegm, croup, and shortness of breath.
Morchella
- known as desert truffles.
- edible hypogeous fungi (grow in arid and semi-arid areas)
- need plenty of rain to develop.
Terfezia
fungal symbionts in the majority of lichens (loosely termed “ascolichens”) such as Cladonia belong to the Ascomycota.
T/F?
T
- few of them parasitize higher plants
- used as a gut laxative and is a source of vitamin B and some proteins
- used in the bread industry
Saccharomyces
cause diseases of the skin and nervous system of humans.
Torulopsis and Blastomycosis
causes cracks in a woman’s vagina.
Yeast vaginiliism
causing mental impairment in humans.
Cryptococcus neoformans
It affects the mucous membrane of the skin, fingers and lung.
Candida albicans
ability to grow where a high osmotic pressure exists
(Aspergillus)
