Fungi Structures
Term | Definition |
---|---|
Perithecium | A globular or flask-shaped ascocarp having an opening or pore (Diaporthe, Gibberella) |
Cleistothecium | A globular ascocarp that is entirely closed (Powdery mildew) |
Pycnidia | An asexual, spherical or flask-shaped fruiting body lined with conidiophores and that produce conidia (Diplodia, Septoria) |
Acervulus | a subepidermal, saucer-shaped, asexual fruiting body producing conidia on short conidiophores (Colletotrichum) |
Sporodochium | An asexual fruiting structure consisting of a cluster of conidiophores woven together on a mass of hyphae (Fusarium). Compact mass of hyphae that erupts with conidia |
Sclerotia | A compact mass of hyphae with or without host tissue, usually with a dark rind, and capable of surviving unfavorable environmental conditions |
Conidiophores | A specialized hyphen branch on which one or more conidia are produces. A conidium is an asexual spore of one or more cells (Botrytis, Alternaria) |
Ascostromata | An ascocarp that bears asci within cavities called locules (Botryosphaeria) |
Conks | A woody basidiocarp of wood-rotting fungi that has pores on the lower surface in which basidiospore are formed (Gandoderma) |
Uredinia | The subepidermal fruiting structure of the rust fungi in which urediniospores are formed (Puccini) |
Rhizoctonia | Right angle hyphae |
Oospores | a thick-walled, sexual spore produced by union of oogonium and antheridium |
Gymnothecia | (naked) a loose, open network of woven hyphae containing globes or pear-shaped asci |
Apothecia | (cup) fruiting body in which the asci form a definite hymenium layer on its upper surface and remains exposed |
Ascus | a saclike structure produced by fungi of the phylum Ascomycota (sac fungi) in which sexually produced spores (ascospores), usually four or eight in number, are formed. Produced in a fruiting body |
Synnema | A long, branched structured containing many spore-bearing structures (conidiophores) |
Free conidia | Produced directly from conidiophores derived from hyphae |
