Anamorph
Sexual form of a fungus
Teleomorph
A cell that produces and extrudes conidia
Annellide
Ability of a fungus to use a specific carbon or nitrogen source for growth
Assimilation
Enlarged, dome-shaped tip of a sporangiophore that extends into the sporangium
Columella
A cell that produces conidia
Conidiogenous cell
Prefix; meaning dark (brownish or blackish)
Pheo-
A subcutaneous or systemic disease caused by a variety of black fungi
Phaeohyphomycosis
Conidia cut off sharply; ending abruptly with a flattened edge
Truncate
Gk: taxis
arrangement
Gk: anomia
method
A specialized hyphal structure that serves as a stalk on which conidia are formed
Conidiophore
An asexual propagule that forms on the side or on the end of the hypha or conidiophore
Conidium
Fungus with cross walls
Septate
Fungus without cross walls
Aseptate
Results from nuclear division within a cell w/o division in the cytoplasm
Coenocytic hyphae
Characterized by multiple projections in a hypha
resembles an OLD COMB hyphae appearance
Pectinate
Hyphae with club-shaped cells;
the layer end of one cell being attached to the smaller end of an adjacent cell
Racquet
Hyphae forming a coiled or CORKSCREW-LIKE turns
Spiral
Terminal hyphae branches that are irregular, broad, and ANTLER-LIKE
Favic chandelier
Round KNOT-LIKE structure by intertwined hyphae
Nodular
produces ROOT-LIKE structures along the vegetative hyphae
Rhizoid
Transparent, clear, and colorless hyphae
Hyaline
Hyphae are brown to black in color,
due to melatonic pigment in the cell walls
Dermaticeous
Forms filamentous (fuzzy) colonies
Apical elongation
Hyphal growth where mycelium is buried down the culture medium for water exchange and nutrient absorption
Vegetative (hyphal growth)
Hyphal growth; projects on the surface of the medium with reproductive structures (spores)
Aerial (hyphal growth)
Types of apical elongation
- Vegetative
2. Aerial
Triggered by stems for the sub-apical accumulation of wall precursors reaching a critical concentration
Lateral elongation
The ability of fungi to grow into 2 forms
Fungal dimorphism
Sex organ, gametes; involves mitosis and meiosis
Gametangium
Developed as a primary nuclear fusion with reduction in chromosome no.
Sexual spores
2-8 ascospores w/in an ascus (sac)
Ascospores
2-4 basidiospores on the surface of basidium
Basidiospores
Product of the sexual fusion bet. 2 sporangiospores to form large thick-walled bodies
Zygospore
Result of the fusion of 2 non-identical hyphae
Oospore
Merging of nuclear material or genes combined
Sporulation, spores
Do not form mycelium;
Produce pasty colonies
Unicellular spores
Form mycelium;
Filamentous colony
Multicellular spores
