Fungus Tissue

1. Plectenchyma (Gr. Plekein = tp weave + enchyma = infusion). During certain stages of fungal development, the mycelium becomes organized into loosely or compact woven tissues, as against the loose hyphae ordinarily found in the mycelium. The organized fungal tissues are called Plectenchyma.

The Plectenchyma is of two Types:

a. Prosenchyma
b. Pseudoparenchyma.
a. Prosenchyma:

The lossely woven tissue in which are closely packed, in the form of more or less parallel to one another is called Prosenchyma.

b. Pseudoparenchyma:

The fungal tissues which are closely packed, in the form of more or less isodiametric or oval cells resembling the parenchyma cells of higher plants are celled Pseudoparenchyma. Both Prosenchyma and Pseudoparenchyma compose various types of vegetative and reproductive structures. Stroma is usually made up of Prosenchyma while scelrotium is made up of pseudoparenchymatous tissue. Both stromata and sclerotia are somatic structure of fungi.
