A dolipore septum is a cross-wall that contains a central pore around which the septum is swollen to form a barrel-shaped structure. http://purl.obolibrary.org/obo/FAO_0001020 hyphal tip, aseptate hypha in mycelium http://purl.obolibrary.org/obo/FAO_0001021 hyphal tip, aseptate hypha The growing end of a hypha that is part of a mycelium, and whose growing portion contains multiple nuclei but is not divided internally by septa. http://purl.obolibrary.org/obo/FAO_0001021 hyphal tip, aseptate hypha http://purl.obolibrary.org/obo/FAO_0001011 hyphal tip The growing end of a hypha that is not divided internally by septa, or cross-walls. http://purl.obolibrary.org/obo/FAO_0001022 mating cell http://purl.obolibrary.org/obo/FAO_0000018 unicellular structure A cell engaged in or about to engage in the process of mating; exhibits different morphology from a vegetative cell due to the action of mating pheromones. http://purl.obolibrary.org/obo/FAO_0001023 shmoo http://purl.obolibrary.org/obo/FAO_0001022 mating cell An elongated, asymmetric cell formed before mating, in response to mating pheromone, by Saccharomyces species and other fungi with similar life cycles. Named after the Al Capp cartoon character, whose shape it resembles. http://purl.obolibrary.org/obo/FAO_0002005 appressorium http://purl.obolibrary.org/obo/FAO_0001001 hypha A modified hypha that forms a specialized structure used by a fungus to penetrate a target. The appressorium first presses against the substrate, usually with a flattened morphology, and then forms a penetration peg that enters the substrate via turgor pressure. Parasitic and mutualistic fungi use appressoria to enter host cells, and some saprotrophs can form appressoria to penetrate non-living substrates. http://purl.obolibrary.org/obo/FAO_0002006 monokaryotic fruitbody http://purl.obolibrary.org/obo/FAO_0000010 sporophore A spore-producing structure that is formed following same-sex (self) mating. These structures are produced by Cryptococcus species in a manner similar to sexual mating except that the resulting spores are isogenic with the parental strain. http://purl.obolibrary.org/obo/FAO_0002007 conidiophore foot cell http://purl.obolibrary.org/obo/FAO_0000018 unicellular structure A specialized cell with an enlarged cell wall that develops from a hyphal cell in a septate mycelium and swells at the aerial terminus to form a conidiophore vesicle. The aerial portion of the foot cell forms the conidiophore stalk. http://purl.obolibrary.org/obo/FAO_0002008 conidial anastomosis tube http://purl.obolibrary.org/obo/FAO_0000001 fungal structure A short, thin, unbranched tubular structure that emerges from a conidium and grows towards, and then fuses with, a similar tube growing from another conidium or conidial germling. http://purl.obolibrary.org/obo/FAO_0002009 spherule http://purl.obolibrary.org/obo/FAO_0000052 sporangium A large, round, thick-walled structure that contains endospores such as those produced by Coccidioides species within a host. http://purl.obolibrary.org/obo/FAO_0002010 sexual structure http://purl.obolibrary.org/obo/FAO_0000001 fungal structure A fungal structure that develops during mating and contributes to sexual reproduction. http://purl.obolibrary.org/obo/FAO_0002011 mating filament http://purl.obolibrary.org/obo/FAO_0001001 hypha A hypha that emerges from a yeast-form cell upon stimulation by the pheromone of a compatible mating partner. An example is observed in Cryptococcus species. http://purl.obolibrary.org/obo/FAO_0002002 multicellular fungal structure http://purl.obolibrary.org/obo/FAO_0000001 fungal structure A fungal structure that comprises more than one cell. http://purl.obolibrary.org/obo/FAO_0002003 multicellular fungal structure, unicellular organism http://purl.obolibrary.org/obo/FAO_0002002 multicellular fungal structure A multicellular fungal structure composed of two or more cells of a single unicellular organism. http://purl.obolibrary.org/obo/FAO_0002004 multicellular fungal structure, multicellular organism http://purl.obolibrary.org/obo/FAO_0002002 multicellular fungal structure A multicellular fungal structure composed of two or more cells of a single multicellular organism. http://purl.obolibrary.org/obo/NCBITaxon_131567 cellular organisms http://purl.obolibrary.org/obo/NCBITaxon_1 root http://purl.obolibrary.org/obo/NCBITaxon_2759 Eukaryota http://purl.obolibrary.org/obo/NCBITaxon_131567 cellular organisms http://purl.obolibrary.org/obo/NCBITaxon_33154 Opisthokonta http://purl.obolibrary.org/obo/NCBITaxon_2759 Eukaryota http://purl.obolibrary.org/obo/NCBITaxon_4751 Fungi http://purl.obolibrary.org/obo/NCBITaxon_33154 Opisthokonta http://purl.obolibrary.org/obo/FAO_0001026 obsolete mycobiont OBSOLETE.
