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').
[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.
Type of spore-bearing surface: gills, pores, et cetera. Descriptor of the general shape of the cap. Descriptor of how the hymenium attaches to the stem. Applies even to ridged, toothed and pored species, despite parameter name. Indicates if a universal or partial veil is present. Color of the spore print. Indicates how the mushroom obtains ...
The spores of Myxogastria are haploid, mainly round and measure between 5 μm and 20 μm, rarely up to 24 μm in diameter. Their surface is generally reticular, sharp, warty or spiky and very rarely smooth. The typical colour of the spore mass becomes visible through the structure, since the spores themselves are not pigmented.
[10] Mycena galericulata produces a white spore print. The spores are ellipsoid, 8–10 by 5.5–7 μm, and amyloid—which means they will turn blue-black to black when stained with Melzer's reagent. The basidia (spore-bearing cells) have stout sterigmata, and measure 34–40 by 7–9 μm. They may be either two-spored or four-spored.
The spore-bearing cells, the basidia, are thin-walled, club-shaped to roughly cylindrical, and measure 2–25 by 5–7 μm. They bear either two or four spores. They bear either two or four spores. The pleurocystidia ( cystidia that are found on the face of a gill) are roughly cylindrical with rounded ends, thin-walled, and 40–55 by 5–8 μm.
Mature sclerotia will produce spore-bearing structures known as clavula, where basidia and basidiospores can form. During the winter, the sclerotia begin to germinate and produce mycelium under a snow cover. The mycelium eventually spreads, produces infection cushions, and penetrates plant tissue.
Spores have a germ pore, a flattened area in the center of the spore surface through which a germ tube may emerge. [23] The spore-bearing cells (the basidia) are four-spored, club-shaped, and measure 10–15 by 4–7 μm. [27] Studies have shown that the basidia develop in four discrete generations.
