27
how do we classify fungi
based on their mode of sexual reproduction
28
Ascomycotina (classification of fungi)
higher fungi, septate, ascospores
29
Basidiomycotina
higher fungi, septate, basidiospores
30
Chytridiomycotina
lower fungi, a septate, Oospores, water mold
31
Zygomycotina
lower fungi and aseptate, zygospores (bread molds)
