Pseudoparenchyma

A pseudoparenchyma (Greek), which is also known as sham tissue, is a tissue-like cell structure. It occurs when cell threads or hyphae are very tightly intertwined and interwoven so that the cell structure appears like a real tissue ( parenchyma ) under the microscope . Pseudoparenchyma occur mainly in (some) red algae , higher fungi and lichens . In contrast to a real parenchyma, the cell threads or hyphae (in fungi) subsequently grow together, often with gelatinous dissolution of the cell wall. The term plectenchyma (plaiting materials) is often used interchangeably. Strictly speaking, however, the cell threads in a plectenchyma are only closely interwoven, whereas in a pseudoparenchyma they subsequently grow together. It goes without saying that both cell structures merge seamlessly and are often difficult to tell apart.
