[5] [6] The genus name "Lomentospora" referred to the shape of the apex of the spore-bearing cell, which the authors interpreted to be a rachis resembling a bean pod of the sort constricted at each seed. The species epithet "prolificans" derived from the prolific nature of the mold's sporulation.
The plasmodia abandon their nutrient intake and crawl, attracted by light – a positive phototaxis – towards a dry, light area, to get an optimal spread of the spores. Once the fructification begins, it cannot be stopped. If disturbances occur, malformed spore-bearing fruit bodies are often produced. [11] [19] Woodlouse with myxogastria spores
An ascus (from Ancient Greek ἀσκός (askós) 'skin bag, wineskin'; pl.: asci) [1] is the sexual spore-bearing cell produced in ascomycete fungi. Each ascus usually contains eight ascospores (or octad), produced by meiosis followed, in most species, by a mitotic cell division.
[8] In general, identification to genus can often be accomplished in the field using a local field guide. Identification to species, however, requires more effort. A mushroom develops from a button stage into a mature structure, and only the latter can provide certain characteristics needed for the identification of the species.
The spore-bearing sporangiophores of Phycomyces are very sensitive to different environmental signals including light, gravity, wind, chemicals, and adjacent objects. They exhibit phototropic growth: most Phycomyces research has focused on sporangiophore photobiology , such as phototropism and photomecism ('light growth response').
"We don't recommend cutting mold off of bread, because it's a soft food," Marianne Gravely, a senior technical information specialist for the United States Department of Agriculture, told NPR ...
A cluster of conidiophore s bearing the spore mass, like a cushion. [363] statismospore A spore that is not forcibly discharged, unlike a ballistospore. Seen in the basidiospores of Gastromycetes. From Gr. statis, immobility. [364] stellate Like a star in form, especially spores. [365] sterigma. pl. sterigmata
It is up to 7.5 cm (3 in) broad and 2.5 to 5 cm (1 to 2 in) high, rounded to variously lobed or brain-like in appearance. The fruit body is gelatin-like but tough when wet, and hard when dry. The surface is usually smooth, the lobes translucent, deep yellow or bright yellow-orange, fading to pale yellow, rarely unpigmented and white or colorless.
