Question 2: Basidiomycota (pronounced /bəˌsidiː.ɵmaɪˈkoʊtə/) is one of two large phyla that, together with the ________, comprise the subkingdom Dikarya (often referred to as the "higher fungi") within the Kingdom Fungi.

Question 3: Previously the entire Basidiomycota were called Basidiomycetes, an invalid class level name coined in 1959 as a counterpart to the ________, when neither of these taxa were recognized as phyla.

Question 4: ________ follows shortly with the production of 4 haploid nuclei that migrate into 4 external, usually apical basidiospores.

Question 5: This stage, numbered "0", produces single-celled, minute spores that ooze out in a sweet liquid and that act as nonmotile ________, and also protruding receptive hyphae.
FertilisationSpermSpermatozoonSexual reproduction

Question 6: Basidia are microscopic but they are often produced on or in multicelled large fructifications called basidiocarps or basidiomes, or fruitbodies), variously called ________, puffballs, etc.
MushroomEdible mushroomAgaricus bisporusYeast

Question 7: ________ and probably other vectors such as rain carry the spermatia from spermagonia to spermagonia, cross inoculating the mating types.

Question 8: The Basidiomycota had traditionally been divided into 2 obsolete classes, the Homobasidiomycetes (including true ________); and the Heterobasidiomycetes (the Jelly, Rust and Smut fungi).
MushroomEdible mushroomYeastAgaricus bisporus

Question 9: For example, the chanterelle genus Craterellus often has 6-spored basidia, while some corticioid Sistotrema species can have 2-, 4-, 6-, or 8-spored basidia, and the cultivated button mushroom, ________.
FungusAgaricus bisporusAgaricus xanthodermusAgaricus campestris

Question 10: This results in the fact that following ________, the resulting haploid basidiospores and resultant monokaryons, have nuclei that are compatible with 50% (if bipolar) or 25% (if tetrapolar) of their sister basidiospores (and their resultant monokaryons) because the mating genes must differ for them to be compatible.
