“…Our present knowledge of fungal mating systems relies heavily on observations of sexual reproductive behaviour in culture. Species are broadly classified into those which are able to reproduce without the need for cross-fertilisation (homothallic), and those which must be fertilised by a compatible genotype for complete sexual development (heterothallic) (Whitehouse, 1949;Burnett, 1956;Raper, 1966). This classification, while useful as a first step, is wholly inadequate for describing fungal mating systems in a quantitative manner and has two serious drawbacks.…”

The mating system of the ascomycete forest pathogen Crumenulopsis sororia was investigated using naturally occurring isozyme genetic markers and appropriate genetic models. Mating was found to occur exclusively through outcrossing. For 8 of the 25 apothecia scored, more than one mate parent was involved in giving rise to ascogenous hyphae. Substantial subdivision occurs within the population which is composed of genetically differentiated subpopulations occupying discrete lesions on host trees.

“…Perhaps Burnett (1956) has supplied the answer in observing that, "A particularly prolific source of confusion has resulted from attempts to transfer concepts originally applied to flowering plants or animals to the fungi".…”

SUMMARYThe random migration of meiotic products to give binucleate spores in secondarily homothallic basidiomycetes gives frequencies of nuclear association which have not previously been recognised.For a single segregating factor in two-spored species, the probability of a basidiospore receiving unlike nuclei is twice that of it receiving like nuclei.Consequently random spore progenies can be expected to yield genotypic ratios of 1:4: 1 with the heteroallelic class predominating. If eight nuclei are present in the basidia of four-spored species then random migration would favour unlike over like pairing in the proportion 4:3; this would give a genotypic ratio of 3 :8:3. Extrapolations are made for two and n factors, and the expected phenotypic ratios for mating-type factors, auxotrophic markers and sporophore characters are derived. Second division segregation and chromosome mapping are also considered.Random nuclear migration in secondarily homothallic basidiomycetes favours heteroallelism and provides a simple explanation for the regularly observed preponderance of isolates heteroallelic for mating-type.

“…Some new and some old genetic concepts were applied and the mating-type factors were elevated from plain alleles to pseudo-, iso-, and codominant alleles and to supergenes on the structural level and to regulator, master, and switch, genes on the functional level (Lewis, 1954;Raper, 1954;Burnett, 1956;Olive, 1958;Griffiths and DeLange, 1978).…”
