A basidiospore is a reproductive spore produced by basidiomycete fungi, a grouping that includes mushrooms, shelf fungi, rusts, and smuts. Basidiospores typically each contain one haploid nucleus that is the product of meiosis , and they are produced by specialized fungal cells called basidia .
Armillaria mellea, commonly known as honey fungus, is an edible basidiomycete fungus in the genus Armillaria. It is a plant pathogen and part of a cryptic species complex of closely related and morphologically similar species. It causes Armillaria root rot in many plant species and produces mushrooms around the base of trees it has infected.
When a basidiospore matures, sugars present in the cell wall begin to serve as condensation loci for water vapour in the air. Two separate regions of condensation are critical. At the pointed tip of the spore (the hilum) closest to the supporting basidium, Buller's drop builds up as a large, almost spherical water droplet.
How does someone get Valley fever? Lung infection caused by fungus in soil leads to symptoms including cough and fever. Disease starts when breathing in spores.
These fungi are said to be homothallic, versus the normal heterothallic species with mating types. Others are secondarily homothallic, in that two compatible nuclei following meiosis migrate into each basidiospore, which is then dispersed as a pre-existing dikaryon. Often such species form only two spores per basidium, but that too varies.
The fruitbody is part of the sexual phase of a fungal life cycle, [1] while the rest of the life cycle is characterized by vegetative mycelial growth and asexual spore production. The sporocarp of a basidiomycete is known as a basidiocarp or basidiome , while the fruitbody of an ascomycete is known as an ascocarp .
Symptoms caused by mold allergy are: watery, itchy eyes; a chronic cough; headaches or migraines; difficulty breathing; rashes; tiredness; sinus problems; nasal blockage and frequent sneezing. Molds can also pose a hazard to human and animal health when they are consumed following the growth of certain mold species in stored food.
Basidiobolomycosis is a fungal disease caused by Basidiobolus ranarum. [1] [5] It may appear as one or more painless firm nodules in the skin which becomes purplish with an edge that appears to be slowly growing outwards. [3] [5] A serious but less common type affects the stomach and intestine, which usually presents with abdominal pain, fever ...
