The mushroom life cycle is similar to that of the filamentous Ascomycota in that following monokaryons formation, there is a prolonged dikaryon stage prior to to karyogamy. However, a significant difference is that sexual organs are absent. It is thought that sexual organs of Basidiomycetes were lost during their evolution and that vegetative hyphae have taken over the function of sexual organs. Dikaryon formation begins with the fusion of hyphal cells between compatible monokayons (Fig. 3). The monokaryon stage of the Basidiomycotina is short-lived and fusion with a compatible monokaryon occurs soon after basidiospore germination. The dikaryon is the mycelium that produces the basidiocarp, and as in the Ascomycota, only certain dikaryotic cells will function in basidia and basidiospore formation, e.g. dikaryotic cells in the hymenium (Fig. 4).
Figure 3: Dikaryon formation resulting from fusion of a pair of compatible monokaryons. Clamp connects may or may not be present.Figure 4: Formation of basidiocarp. Hymenial cells (right), in lamella will undergo karyogamy and develop basidia and basidiospores
The terminal cells develop into basida and is where karyogamy will take place to form the zygotes. The zygote is the only diploid stage in the life cycle. The zygote immediately undergoes meiosis to form four haploid nuclei, and the future basidiospores are formed as blown out structures, on the tips of sterigmata, of the basidium. The nuclei migrates into the blown out areas which may then be properly referred to as basidiospores (Fig. 5).

Unlike other life cycles that we have covered, with only some variations, the sequence of events in the mushroom life cycle is truly representative of the class Basidiomycetes.
The cap .

the ring .
the stem . (all together) spore
the volva .
the hypha .
the mycelium .
The main part of a mushroom is underground. It is called the mycelium.
A mushroom has two parts, the mycelium and the fruit. The functions of these parts is to provide food and for the absorption of water.
there are 4 parts
there is the
cap (pileus)
gills (lamellae)
stem (stipe or stalk)
ring (annulus)
Cap,gill and stalk
The longest living mushroom lived up to 2,400 years
A moth has a 4-stage life cycle.
yes because mushrooms are a tybe of plant and all plants are living
Aspergillus is a haploid fungi its life cycle involve both sexual and asexual cycle.
In my class we are starting learning about the life cycle
I Think ....... maybe mushroom is blown by wind but the apple tree is drop down and maybe .....
Conception and death.
The thallus is haploid. It depends on the three basic life cycle of sexually reproducing fungi, in haplobiontic A life cycle, the thallus is haploid, in haplobiontic B life cycle the thallus is diploid and in diplobiontic life cycle, it has two thallus, a sporophytic thallus which is diploid and a gametophytic thallus which is haploid.
