THE KINGDOM FUNGI Classification of Fungi

CLASSIFICATION OF FUNGI (KNOW CHART ON PAGE 281) § classified according to their colonial structure and method of sexual reproduction § most common phyla (first three) • Zygomycota • Ascomycota • Basidiomycota • Deuteromycota (imperfect fungi)

PHYLUM ZYGOMYCOTA § representative organism Rhizopus (bread mold) § sexual reproduction zygosporangia § asexual reproduction sporangiophores

SEXUAL REPRODUCTION germinating zygotes zygosporangium different mating types hyphae fusing

ASEXUAL REPRODUCTION sporangia asexual spores rhizoids in bread

PHYLUM ASCOMYCOTA § “sac fungi” § representative organisms • Penicillium • powdery mildews • yeasts § sexual reproduction produce ascospores in an ascus § asexual reproduction conidiophores

SEXUAL REPRODUCTION fruiting body asci different mating types germination released ascospores

ASEXUAL REPRODUCTION conidia germination conidiophore

PHYLUM BASIDIOMYCOTA § “club fungi” § representative organisms • mushrooms • puffballs • rusts • smuts § sexual reproduction produce basidiospores on a basidium § asexual reproduction not as common as other phyla

basidiospores gills basidiocarp basidium

PERFECT FUNGI § “true fungi” § have a known method of sexual reproduction

IMPERFECT FUNGI § have no known method of sexual reproduction § examples • ringworm • athlete’s foot

LICHENS § composed of an alga and a fungus § formed by symbiosis the relationship of two organisms living together § reproduce by soredia § three types § crustose § foliose § fruticose
