SummaryThe basidia of Coprinus radiatus develop synchronously. Both meiotic divisions happen within 30–40 min. During this time an undifferentiated centriole appears, divides and forms the spindle poles by radiating microtubules. For the nuclear envelope breaks down in the metaphase and restituates during telophase the meiosis is not intranuclear.In meiotic basidia ER is regularly to be seen near the cell wall, it may be compared with the “ascus vesicle”. Moreover an organized ER-complex occurs… 

Intranucleäre Spindeln und Reduktion des Kernvolumens bei der Meiose von Coprinus radiatus (Bolt) Fr.

Throughout both meiotic divisions in Coprinus radiatus the spindle apparatus acts within an intact nuclear envelope. The centriol equivalents penetrate the nuclear membrane and develop to the spindle

Intranucleäre Mitosen in homokaryotischen und dikaryotischen Mycelien der Basidiomyceten

The volume of the premitotic nucleus is reduced by separating the division nucleus from a residual nucleus which is surrounded by a membrane for the nuclear membrane persists throughout the mitosis the spindle apparatus acts intranuclear.

Light and electron microscopic studies of meiosis in the basidia ofPholiota terrestris

The meiotic apparatus in P. terrestris is considered to have the same fundamental features as those of plants and animals and in detail conforms to the pattern described in several light and electron microscopic studies of other Homobasidiomycetes.

Mitosis in the basidiomycete fungusTulasnella araneosa

It is indicated that the spindle pole body (SPB) of T. araneosa is more different from that of Uredinales than it is from representatives of the other four orders ofBasidiomycotina that have been thoroughly studied.

The mitotic apparatus of a zygomycete, Phycomyces blakesleeanus

SummaryA novel type of mitotic apparatus is described in Phycomyces blakesleeanus. Its spindle consists of a pole-to-pole bundle of regularly spaced microtubules which terminally insert in an

MITOSIS IN HETEROBASIDIOMYCETOUS YEASTS

The sequence of chromatin movement into the bud of L. scottii, division inside the bud, and return of one daughter nucleus to the mother cell, is closely comparable to the movements of Chromatin in and out of clamp connexions known to occur in dikaryotic hyphae of Polystictus versicolor.

Septal pore apparatus and nuclear division of Auriscalpium vulgare

Ultrastructure of the septal pore apparatus and nuclear division of Auriscalpium vulgare (Russulales) was examined with freeze substitution andStructural characters may distinguish one or more clades of the Agaricomycotina and provide additional signal in phylogenetic analyses.

A double unit-membrane system surrounds all cell organelles except y-bodies, vacuoles and a few fragments of membranes and there appears to be no connection between the striated rootlets and the mitochondrion.

Feinbau und Carotinoide von Tribonema (Xanthophyceae)

Evidence is presented that a limited area in the space between the plastid envelope and the surrounding ER-cisterna is occupied by a network of smooth ER-tubules, which suggests that the periplastidal network is of widespread occurrence among the Chromophyta.
