title: Ultrastructure of the dolipore-parenthesome septum in Hirschiporus pargamenus (Polyporaceae).
abstract: The septal complex in hyphae of Hirshioporus pargamenus (Fr.) Bond. & Sing. is generally similar to that described for other Homobasidiomycetes. A noteworthy distinction is the presence of imperforate parenthesomes. A dark line is frequently observed in the inner matrix of the parenthesome. We suggest that this line is an image produced by the overlapping of folded, opposing membranes differentiated from the wall endoplasmic reticulum.
