Question

Ascomycetes ,phycomycetes,basidiomycetes ,deuteromycetes fungi further classification i

Answer 1

) Phycomycetes (The Lower Fungi)

Rhizopus

Mycelium: A septate, Cenocytic

Asexual reproduction: Zoospores, Aplanospores, Chlamydospores, Sporangiospore

Sexual Reproduction: Isogamy, Oogamy

Fruiting body: Zygospore

Examples: Mucor, Rhizopus

b) Ascomycetes(Sac Fungi)


Pencillium

Mycelium:   branched and Septate

Asexual reproduction: Budding, Conidiospores or Conidia

Sexual Reproduction: Fusion of compatible nuclei. Ascospores formed in ascus


A linear, cylindrical, eight-spored ascus of Sordaria fimicola

Fruiting body: Ascocarp (Cleistothecium, perithecium, apothecium)


YeastScarlet cups

 Examples: Yeast, Penicillium, Neurospora, cup fungi, edible morels

c)Basidiomycetes (Club Fungi) : Advanced group of fungi

Agaricus

Mycelium: Secondary, mycelium, dikaryotic

Asexual reproduction: Basidiospores, Oidia

Sexual Reproduction: Somatogamy, Basidiospores formed on sterigmata.

Fruiting body: Basidiocarp

Puff ball

Shelf Fungi                

Examples: Mushroom, Puff balls, bracket fungi, Agaricus, Polyporus, Puccinia, Ustilago

d)Deuteromycetes (Fungi Imperfecti): In these fungi only asexual method of reproduction  by means of conidia has been observed. Perfect or sexual stages are absent. Hence they are grouped under an artificial group called fungi imperfecti.


Fusarium

Mycelium: Branched, septate mycelium

Asexual reproduction: Conidia

Sexual Reproduction: Absent or not known

Fruiting body: Absent

Examples: Fusarium, Collectotrichum, Pyricularia, Cercospora
