3. Agaricus Classification/
Systematic Position - Justification
SubDiv: Eumycetes
• True fungi with cell wall
Class: Basidiomycetes
• They produce a unique type of sporangium called
Basidium
• Definite number of spores called Basidiospores
• Usually 4 basidiospores are produced on basidium
• Rarely produce 2 or 3
• In addition to the basidiospores other type of spores
are also produced

4. Sub Class: Homobasidiomycetes
• Basidia not septate or deeply divided (They produce
holobasidia which are entire)
Series: Hymenomycetes
• Hymenium exposed before the basidiospore formed
Order: Agaricales
• All are saprophytic and with definite basidiocarp
• Show clamp connection
• Primary mycelium forms secondary mycelium by
Plasmogamy(also called as Somatogamy)

5. Family: Agaricaceae
Genus: Agaricus
