Adapted to liquids• unicellular - most
reproduction is asexual and takes
• place by cell fission or budding• ferment carbohydrates -
produce ethanol as byproduct

• Rapidly growth• Asexual spores• Many human importances
– Food spoilage– Food products– Antibiotics, etc.

Reproduction of fungi
• Unicell fungi: a. asexual : division, buding, asexual sporeb. sexual : sexual spore
• Multicell fungi :a. asexual : - fragmentation
- zoospora - konidia
b. sexual : - conjugation - sexual spore

Fungal Ecology
• Heterotrophic (decomposer, parasite, symbiotic)
• Saprobes– Decomposers
– Mostly of plants, some animals
• Parasites– Harm host
– Mostly on plants, some animals
• Mutualists– Lichens symbiosis fungus + alga or cyanobacteria
– Mycorrhizas symbiosis fungus + root plant

Chytridiomycota – “chytrids”
• Simple fungi
• Produce motile spores
• Mostly saprobes and parasites in aquatic habitats
• Could just as well be Protists

Zygomycota – “zygote fungi”
• Hyphae has no partition (aseptate)• 3 types of hyphae :
a. rhizoid b. stolon c. sporangiofor have
sporangium • Reproduction:
a. sexual : conjugation zygospora (diploid)
b. asexual : sporangiofor

Ascomycota
• Hypha is partitioned (septate)• Haploid nucleus• Reproduction :sexual : ascospore that formed by ascus, a group of ascus forming fruiting body
(askokarp)
• The ascocarp carries asci within cupsasexual :
Multicell fungus : conidia/ conidiospore produced by konidiofor,,Unicell fungus : buding (blastospora)• Some have mutualistic relationships with cyanophyte to
form Lichenes

Basidiomycota
They are multiple cell organisms. Their myceliums are at their substrate of live. They have segmented hypha with one or two nuclei. Each of them performs a fruit bag that is called basidiocarps, which are the places for basidium. Production. Each basidium has 4 basidiosphores.
Try to compare the differences between ascus and basidium. The fruit bag size is large with many kinds of shapes.
They have vegetative reproduction by means of conidia or fragmentation and generative reproduction by creating basidiosphores.

Eatable BasidiomycotaVolvariella volvaceae have umbrella – like fruit bag shapes. They grow at cellulose medium, such as dry rice – straw. They are often called rice – straw mushroom. Auricularia polytricha (yellow mushroom), they have fruit bag shapes like the ones on ear mushroom. They grow at died stems. Lentinus endodes (shitake) that being grew widely on China and Japan. They grow at wood stem lump Pleuroteswith fan – like shape fruit bag. They grow on ligneous and cellulous substrate, such as saw grain.

They are multiple cell organism with segmented hypha. It is rarely that they have fruit bag. Their vegetative reproductions are by means of conidia, and their generative ones are not known yet. They are called as imperfect fungi. Some kinds of Deuteromycota are:
• Epydermophyton floocossum, athlete feet disease initiates• Microsporum and Trighophyton, ringworm disease initiates.• Sclerothium rolfsie, rotten disease of cultivation crops initiates• Candida albicans, look like yeast and live parasitically. They can
cause infection on the vagina.• Chladosporium• Curvularia• Monilia sitophyla (oncom fungi). Formerly, they are grouped as
Deuteromycota, but after finding their sexual reproduction that is by ascuis, they are then grouped at Ascmocota by name of Neurospora crassa.

Type of fungi symbiosis
Myccorrhiza Mycorrhiza is a kind of symbiosis type of fungi and plant root. • EctomycorrhizaEctomycorrhiza is a kind of mycorrhiza symbiosis procces, with fungi hypha perforation do not reach cortex, but reach epidermis only.For examples, pines and belinjo tree symbiosis with a certain fungi of Basidiomycota division.• EndomycorrhizaEndomycorrhiza is a kind mycorrhiza symbiosis process, with fungi hypha perforation capable of reaching the cortex part of plant.For examples, vegetables plants, such as cabbage, symbiosis with a certain fungi of Zygomycota division.

Lichens Lichens are kinds of symbiosis of algae and fungi. The fungi obtain food from the alga photosynthesis products. The algae obtain water and mineral from the fungi.•Parmelia sp.They live at stem skin, look like a grey crust.•Graphis sp.They are also called as line lichens, with a shaper of smaal sketches.They live epiphytically at plant stem skin.•Usnea sp.They are also called as beard lichens. The ends of their bodies are like hanging thread on the air. They stick on the plant stem, especially on mountainous plants. They produce antibiotics, usnin acid and bioticum tuberculoses, so they are used as drugs.
