真菌(fungus)
真核细胞型微生物
主要特征
具有典型的细胞核及完善的细胞器,不含叶绿素(chlorophyll),无根、茎、叶的分化
以寄生或腐生方式生存,进行无性或有性繁殖
大多数为多细胞,少数为单细胞
There are between 100,000 to 200,000 species depending on how they are classified
About 300 species are presently known to be pathogenic for man

Medically important fungi
Includes 4 phyla
ycota(子囊菌门)- Sexual reproduction in a sack called an ascus with the production of ascopspores.
Basidiomycota(担子菌门)-Sexual reproduction in a sack called a basidium with the production of basidiospores.
Zygomycota(接合菌门) - sexual reproduction by gametes and asexual reproduction with the formation of zygospores.
Mitosporic Fungi(Fungi Imperfecti,半知菌门) - no recognizable form of sexual reproduction. Includes most pathogenic fungi.
