Deuteromycota (Fungi Imperfecti): Characteristics and Examples

📚 Quick Study Guide

• 🍄 Deuteromycota, also known as Fungi Imperfecti, are fungi that do not fit into the commonly established taxonomic classifications of fungi due to their lack of a known sexual reproductive cycle.
• 🔬 Reproduction is primarily asexual, occurring through conidia (asexual spores).
• 🧬 Because many are only known in their asexual form, placing them in a specific phylum is challenging.
• 🌱 Many are plant pathogens, causing diseases in crops and other plants.
• 👨‍⚕️ Some species can also be pathogenic to humans, causing various infections.
• 🧪 Identification is often based on morphological characteristics of the conidia and conidiophores (specialized structures bearing conidia).
• 🍁 Examples include *Aspergillus*, *Penicillium*, and *Alternaria*.
