Characteristics of the Major Classes of Fungi Flashcards
Chapter 2
Acervulus
A subepidermal, saucer-shaped,asexual fruting body producing conidia on short conidiophores.
Ascomycetes
Asexual
Apothecium
An open cup- or saucer-shaped ascocarp.
Ascomycetes
Sexual
Ascospores
A sexually produced spore borne in an ascus.
Ascomycetes
Ascus
A scalike cell of hypha in which meiosis occurs and which contains the ascospores (usually 8)
Ascomycetes
Aseptate
Having no cross walls; lacking septa.
Basidiospore
Haploid (1N) sexual spore produced on a basidium.
Basidiomycetes
Chlamydospore
Thick walled or double walled asexual resting spore formed from hyphal cells (terminal or intercalary) or by transformation of conidial cell that can function as an overwintering stage.
Deuteromycetes
Coenocytic
Having multiple nuclei embedded in cytoplasm without cross walls.
Conidiophore
Simple or branched hypha on which conidia are produced.
Ascomycetes, Basidiomycetes, & Deuteromycetes
Asexual
Synnema
-or-
Coremium
A headlike cluster formed by compact or fused, genereally upright condiophores, with branches and spores.
Mushroom
Fleshy fruiting body of a fungus.
Basidiomycetes
Non-septate
Lacking cross walls; septa are absent from hyphae.
Oospore
Thick walled, sexually produced resting spore.
Oomycetes
Perithecium
Flask-shaped, thin-walled fungus fruting body (ascocarp) containing asci and ascospores; spores are expelled through a pore (ostiole) at the apex.
Ascomycetes
Asexual
Plasmodium
Exposed, multinucleate mass of protoplasm moving and feeding in amoeboid fashion.
Myxomycetes & Plasmodiophoromycetes
Pycnidium
Asexual, globose or flask-shaped fruting body containing conidia.
Sclerotium
A vegetative resting body of a fungus, composed of a compact mass of hyphae with or without host tissue, ususally with a darkened rind.
Sporangiophore
Sporangium-bearing body of a fungus.
Sporangiospore
Nonmotile, asexual spore that is borne in a sporangium.
Sporangium
Saclike fungal structure in which the entire contents are converted into an indefinite number of asexual spores.
Sporodochium
Superficial, cushion-shaped asexual fruiting body consisting of a cluster of conidiophores.
Stroma
Compact mass of mycelium that supports fruiting bodies or in which fruiting bodies are embedded.
Zoospore
Spore with flagella, capable of locomotion in water.
Zygospore
Sexual resting spore formed from the union of gametangia.
Zygomycetes
