TLDR
All newly established dikaryons from reciprocal crosses between compatible monokaryons carrying different mtDNA RFLP phenotypes retained mtDNA genotypes from one of the monokARYons, suggesting that mitochondrial inheritance is principally uniparental.Abstract:
By using mitochondrial DNA (mtDNA) restriction fragment length polymorphisms (RFLPs) as genetic markers, the modes of mitochondrial inheritance in sexual crosses and protoplast cell fusions of the higher basidiomycete Lentinula edodes were examined. All newly established dikaryons from reciprocal crosses between compatible monokaryons carrying different mtDNA RFLP phenotypes retained mtDNA genotypes from one of the monokaryons, suggesting that mitochondrial inheritance is principally uniparental. In contrast, it was shown that recombinant mtDNA genomes arose in some dikaryons obtained after protoplast cell fusion. Based on these results, a possible mechanism for mitochondrial inheritance in L. edodes is discussed.read more

Uniparental inheritance of mitochondrial and chloroplast genes: mechanisms and evolution.
TL;DR: In nearly all eukaryotes, at least some individuals inherit mitochondrial and chloroplast genes from only one parent; consequently, their inheritance is asexual.

Having sex, yes, but with whom? Inferences from fungi on the evolution of anisogamy and mating types.

TL;DR: It is argued that fungi represent highly suitable models to help resolve issues related to the evolution of distinct gamete classes, because the number of mating types vary from zero to thousands across taxa, anisogamy is present or not, and because there are frequent transitions between these conditions.

mtDNA recombination in a natural population
TL;DR: The genotypic structure of mtDNA in a natural population of the basidiomycete fungus Armillaria gallica is inconsistent with purely clonal mtDNA evolution and is fully consistent with mtDNA recombination.

TL;DR: Restriction fragment length polymorphism in the large ribosomal RNA region of the mitochondrial DNA (mtDNA) was developed as a genetic marker for investigating mitochondrial transmission in sexual crosses of the human pathogenic basidiomycetous yeast Cryptococcus neoformans.

Genetic exchange and recombination in populations of the root‐infecting fungus Armillaria gallica
TL;DR: The apparent linkage equilibrium between some pairs of loci and the high level of phylogenetic inconsistency among all four loci suggest the occurrence heteroplasmy and recombination among mtDNAs of A. gallica in nature.

TL;DR: It is reported here, however, that the mitochondrial (mt) DNAs of cybrids are different from those of the parents and from the mixture of the two.

A Case of “Maternal” Inheritance in Neurospora Crassa
TL;DR: The inheritance of mutant characters of Neurospora has not previously been found to be influenced by the way in which crosses were made, but the inheritance of a slow-growth character, which has been designated as poky, appears to be dependent upon its being carried by the protoperithecial parent.

TL;DR: Interestingly, it was found that mating asymmetry, caused by nonreciprocal nuclear migration, may be an important part of the reproductive biology of C. cinereus.
