Mushroom spawn is a substrate that already has mycelium growing on it. [1] [2] Mycelium, or actively growing mushroom culture, is placed on growth substrate to seed or introduce mushrooms to grow on a substrate. This is also known as inoculation, spawning or adding spawn.
The termites eat spherules [note 1] and old combs. [12] The fungus forms mushrooms for spreading spores. For most species, the fungus grows long pseudorhizas to the surface of the ground, where mushrooms are formed. [13] For T. microcarpus, the mushrooms grow from fragments of fungus garden that are carried outside the nest by worker termites. [14]
Instead of seeds, mushrooms reproduce through spores. Spores can be contaminated with airborne microorganisms , which will interfere with mushroom growth and prevent a healthy crop. Mycelium , or actively growing mushroom culture, is placed on a substrate—usually sterilized grains such as rye or millet—and induced to grow into those grains.
The short stipe measures 5–17 cm (2– 6 + 3 ⁄ 4 in) high by 1–2 cm in diameter, [5] is grey in colour, and lacks a ring. In young groups, the stems may be obscured by the caps. [6] The spore print is black, [7] [8] and the almond-shaped spores measure 8–11 by 5–6 μm. [9] The flesh is thin and pale grey in colour. [3]
The fruiting bodies of many larger fungi such as the chanterelle and the cep are collected as edible mushrooms. [5] [6] Some, such as truffles, are esteemed as costly delicacies. [7] A few species such as Agaricus bisporus and oyster mushrooms (Pleurotus spp.) are cultivated. [8] Mould fungi produce foods like tempeh, savoury Javanese fermented ...
Amanita verna, commonly known as the fool's mushroom or the spring destroying angel (see destroying angel), [2] is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Occurring in Europe in spring, A. verna associates with various deciduous and coniferous trees.
A mycorrhiza is a symbiotic association between a green plant and a fungus. The plant makes organic molecules by photosynthesis and supplies them to the fungus in the form of sugars or lipids, while the fungus supplies the plant with water and mineral nutrients, such as phosphorus, taken from the soil.
In macrocyclic and demicyclic life cycles, the rust may be either host alternating (heteroecious) (i.e., the aecial stage is on one kind of plant but the telial stage on a different and unrelated plant), or single-host (i.e., the aecial and telial states on the same plant host). [3]
