Basidiomycota Ascomycota Glomeromycota Zygomycota Chytridiomycota phylum glomeromycota Class: Glomeromycetes “Soil Fungi” General Characteristics Newly established phylum Very common, yet rarely seen, group of fungi can be found in majority of plants Produces blastopore (blastoconidia) - large, multinucleated phylum glomeromycota Class: Glomeromycetes General Characteristics general characteristics: habitat and habit Primarily terrestrial Symbiotic relationship general characteristics: morphology Coenocytic Glomeromycetes generally exist as filamentous hyphae general characteristics: morphology Form arbuscules Form Mycorrhizae (fungus root) general characteristics: morphology Mycorrhizae Form associations with roots of trees and herbaceous plants Specifically endomycorrhizal Grow inside the plant root cells Called Arbuscular mycorrhizae form tree-shaped structures general characteristics: morphology Roots supply organic nutrients for fungus Fungus provides mineral nutrients for plant Basidiomycota Ascomycota Glomeromycota Zygomycota Chytridiomycota phylum zygomycota Class: Zygomycetes, Trichomycetes “Zygote fungi” Conjugating fungi General Characteristics They lack flagella They have the capacity for both sexual (zygospores) and asexual (sporangiospores) reproduction Has more than 1000 species phylum zygomycota Class: Zygomycetes Class: Trichomycetes Mucorales - Includes individuals saprophytic (bread belonged to insects molds) (digestive tract) Entemophthorales - insect parasites general characteristics: habitat and habit Primarily terrestrial Parasitic relationship; Symbiotic general characteristics: morphology Coenocytic Long filaments of hyphae general characteristics: morphology Bread Mold - Rhizopus stolonifer Black bread mold Rhizopus consist of two kinds of hyphae, vegetative and reproductive  Rhizopus stolonifer Ecology & Habitat: Common saprophyte, food decomposer Human and animals Pathogenecity: Opportunistics agent; causes Mucormycosis in immunocompromised individuals Plant pathogenecity: Damages ripe fruit phylum ascomycota Class: Ascomycetes Sac fungi, Cup fungi General Characteristics Mycologists have described over 60,000 species of ascomycetes, or sac fungi. Asexual reproduction (conidia); Sexual reproduction (Ascospores - ASCUS) general characteristics: habitat and habit Live in variety of marine, freshwater and terrestrial habitats They can form mycorrhizal relationships with plants; saprothrophs, parasitic general characteristics: morphology Septate and branched hyphae Examples: Ascomycetes include Yeasts Molds Morels Truffles Pathogenecity Plant pathogenecity Fruit decay and rots Root and stem rots Stem and Trunk Cankers Human/Animals Pathogenecity Candida albicans Aspergillus niger
