Study Notes
Diagnostic Character of Basidiomycota
- Characterized by producing basidiospores on basidia, a specialized reproductive structure.
- Typically contains clamp connections, aiding in dikaryotic cell formation during sexual reproduction.
- Includes various forms, such as mushrooms, puffballs, and shelf fungi, illustrating diverse morphologies.
Dispersal of Basidiospores
- Basidiospores are primarily dispersed by wind, relying on air currents to spread over distances.
- Some species utilize water for dispersal, with spores released during rainfall.
- Dispersal strategies can include the use of animal vectors, although less common.
Difference Between Basidiospores and Ascospores
- Basidiospores are formed on basidia and typically released in groups, while ascospores are formed inside asci of Ascomycota.
- Basidiospores are usually produced via external processes, contrasting with the internal production of ascospores.
- Morphologically, basidiospores are often more varied in shape compared to the usually uniform ascospores.
Approximate Number of Species
- The phylum Basidiomycota comprises around 30,000 species.
- This number includes a wide range of fungi, indicating significant diversity within the group.
Cells Bearing Basidiospores
- The cells that produce and bear basidiospores are called basidia.
- Each basidium typically produces four basidiospores, which are crucial for sexual reproduction in Basidiomycota.
