The presence of thin coals, lycopsid rhizomorphs
, and greenish-grey mudrocks indicates that, at least locally, mires and clastic swamps persisted long enough to allow for lycopsid growth and limited peat accumulation.
This conviction is reinforced also by the result of rhizomorphs
macrostructure comparison: rhizomorphs
of local ecomorphotypes (see table 1) and representants of A.
Macropleurocystidia, Bars= A: 4 mm, B: 10 mm, C: 11 mm Anatomical characteristics of emanating elements (Fig.4D-F): Rhizomorphs
undifferentiated (Type B, Agerer 1987-2002); margins rather smooth, thick, hyphae compactly arranged and thickly interwoven which are very difficult to separate, cells upto 3.5 um in diameter, septate
Stipe 12-15 x 1-3 (apex) 3-6 mm (base), central, terete, tapered at the apex, pale grey (1B1) to yellowish white (1A2), consistency fleshy, smooth to slightly striated, with white mycelial pad and rhizomorphs
These ectomycorrhizae are characterized morphologically by dichotomously branched ramifications with plectenchymatous inner and outer mantle surfaces, differentiated rhizomorphs
, and emanating hyphae.
8).Basidiomata gregarious pyriforme 3050 mm highA- 1535 mm broad off-white when young brown when mature; rhizomorphs
white encrusted with particles of soil and other debris material.
Volva present at the base of stipe, 14-21 X13 mm, saccate, white (4A1), covered with sand, basal rhizomorphs
Duddrige JA, Malibari A, Read DJ (1980) Structure and function of mycorrhizal rhizomorphs
with special reference to their role in water transport.
"It grows arms called rhizomorphs
, which can extend 25 feet to 40 feet away from the root ball and even penetrate non-cellulosic material, such as plaster, concrete and brick and, after having penetrated that barrier, eat the wood on the other side," he said.
Adaptations to terrestrial habitats displayed by some homobasidiomycetes include rootlike rhizomorphs
that allow the fungi to forage along the forest floor, drought-resistant sclerotia, and tough, perennial fruiting bodies.
Sterile base: Well-developed, up to about 1/3 of the fruiting body, interior dull white with small chambers; base bearing many white mycelial threads (rhizomorphs
"This fungus lives in a below-ground habitat, spreading very slowly outward from tree to tree along roots or by growth through the soil using special shoestringlike structures called rhizomorphs
," says Catherine Parks, a biologist with the Forest Service's research station in Portland.
