Doliporus

from Wikipedia, the free encyclopedia

As Doliporus (plural: dolipores) refers to a form of pore (pore) in the transverse wall ( septum ) of the hyphae of many stand mushrooms (Basidiomycota) with bilateral, mostly bowls of the protuberances and characteristic. The septum is expanded into a short tube around the porus. The septum pore is usually enclosed by a thickened membrane called a dolium . The dolipores are 0.1 to 0.2 μm in size. On either side of a doliporus there may be membranous caps called parenthosomes . The parenthosomes are a protuberance of the endoplasmic reticulum . Rust fungi (Pucciniales) and smut fungi (Ustilaginomycotina) do not form parenthosomes.

The presence of a dolipores septum is a significant difference between the hyphae of the fungi and the stator Ascomycetes (Ascomycota), which have a simple septum having circular openings.
