“…Membrane fragments also may be present near the SPB that together do not form a distinct cap. SPB caps that are continuous with the nuclear envelope have been reported for those Agaricomycetes in members of the Boletales (Yoon and McLaughlin 1987), Agaricales (Lerbs 1971, Raju and Lu 1973, Wells 1978, and Polyporales (Girbardt 1968). In contrast species in the Auriculariales (Lü and McLaughlin 1994), Cantharellales (Taylor 1985), Hymenochaetales (Setliff et al 1974) and Russulales (Berbee and Wells 1989) lack SPB caps.…”

Ultrastructure of the septal pore apparatus and nuclear division of Auriscalpium vulgare (Russulales) was examined with freeze substitution and is presented for inclusion in the AFTOL Structural and Biochemical Database (http://aftol.umn.edu). Previously unreported septal characters for the Russulales (Agaricomycotina) were observed: Septa of the hymenophore had bell-shaped perforated septal pore caps that may extend along the septum and a zone of organelle exclusion surrounded the septal pore apparatus. Metaphase I of meiosis and metaphase of mitosis were similar. Globular spindle pole bodies with electron-opaque inclusions were set within polar fenestrae of the nuclear envelope. The nuclear envelope was mostly intact with occasional gaps. Fragments of endoplasmic reticulum were present near the spindle pole bodies but did not form a polar cap. Structural characters may distinguish one or more clades of the Agaricomycotina and provide additional signal in phylogenetic analyses.

“…Only a few studies have been made on the fine structure of basidia in the Homobasidiomycetes (Lerbs 1971 ;Lu 1966;Manocha 1965;Volz et al 1968;Wells 1965). However, none of these papers report the presence of a double membrane surrounding pairs of nuclei such as were found in P. Iatemarginata basidia.…”

Percurrent basidial proliferations in Poria latemarginata are described. After basidiospore discharge, the top of the basidium disintegrates and a new basidium develops inside the walls of the previous basidia. The basidium is then delimited at the base by a septal pore apparatus. As many as 11 basidia may develop from one point. Pairs of nuclei in basidia frequently were surrounded by a double membrane. The placement of P latemarginata in the genus Oxyporus will depend in part on whether or not the type specimen (Oxyporus connatus) has repeating basidia.

“…A golgi apparatus has not previously been reported in postmeiotic basidia of Coprinus lagopus sensu Buller (2,5,6), although this organelle, consisting of a single dictyosome, has been convincingly demonstrated in the vegetative stage of a number of Basidiomycetes (3,4). This paper describes a golgi apparatus in the postmeiotic basidium of C. Iagopus which may be involved in basidiospore formation.…”
