pseudoparenchymatous

The fruit body has the same pseudoparenchymatous cellular morphology.

This ring-shaped swelling is made of remnants from a tissue called the pseudoparenchymatous layer.

The pseudoparenchymatous layer is built up by bladder-like, thin-walled hyphae of varying size.

The order includes families with pseudoparenchymatous (Splachnidiaceae) or true parenchymatous (Scytosiphonaceae) tissue.

The stalk is visible when the pseudoparenchymatous layer has dried up, and is short but distinct, measuring 1-2.5 mm tall.

The ascomata lack paraphyses; the ostiolar canal is formed when pseudoparenchymatous cells in the center of the neck dissolve or tear apart.

The latter species lacks vertical striations on the basal portions of the endoperidium, and does not have a pseudoparenchymatous collar around the stem.

Aside from filamentous forms, there are two main types of tissue organization in the brown algae: pseudoparenchymatous (haplostichous) and parenchymatous (polystichous).

The receptacle consists of thick-walled, roughly spherical pseudoparenchymatous cells 5-15.5 μm thick, that contain intracellular pigment.

The pseudoparenchymatous layer when fresh is about 1-2 mm thick, initially whitish, later turning beige to brownish (sometimes over reddish tints), and dark brown when old.

The fornicate exoperidium (outer peridium) has the upper, arched part (fibrous and pseudoparenchymatous layers) split to about the half-way point or more into 4-7 rays.

When fresh, the pseudoparenchymatous layer is whitish in color, thick and fleshy; it dries to become brown to dark brown while shrinking and often splitting and peeling.

The pseudoparenchymatous layer (a layer of thin-walled, usually angular, randomly arranged cells that are tightly packed) is initially beige, later brownish, in age dark brown, cracked and if moist reddish-brown.

Also present in this outer layer are thick-walled pseudoparenchymatous cells (angular, randomly arranged, and tightly packed) that are 7-50 μm thick, spherical or nearly so, and yellowish-brown to pale brown.

It has a pseudoparenchymatous structure (compactly interwoven short-celled filaments that resemble the parenchyma of higher plants) made of spherical cells that are 12-45 μm diameter that contain intracellular pigment.

In newly expanded specimens this layer is covered with a thin layer of crystals and hyphae, sometimes forming a pseudoparenchymatous cup or collar that often peels off in patches, when dry shrunken and hard.

The inner side, when free from pseudoparenchymatous remnants, is almost white, in age becoming dirty grayish-white and sometimes greenish due to algae; the outer side is initially whitish, somewhat glossy, but in age becomes grayish-white and dull.

The sclerotium is made of hyphae that have yellow pigment in their walls that appear in cross-section to be pseudoparenchymatous (compactly interwoven short-celled hyphae that resemble parenchyma of higher plants), and measure 5-10 μm in diameter.

The surface spines are made of chains of pseudoparenchymatous hyphae (resembling the parenchyma of higher plants), in which the individual hyphal cells are spherical to elliptical in shape, thick-walled (up to 1 μm), and measure 13-40 by 9-35 μm.

The inner pseudoparenchymatous layer (so named for the resemblance to the tightly packed cells of plant parenchyma) is fleshy and thick when fresh, and initially pale beige but darkening to yellow or brown as it matures, often cracking and peeling off in the process.
