Anastomosis is the connection or opening between two things, in this case the mycelium. Mycelium is the vegetative part of the fungus that consists of hyphae. If the two monokaryons are sexually compatible they form a clamp connection. This results in a mycelium consisting of dikaryotic cells. The dikaryon cells predominate in the vegetative phase.
For parasitic fungi, they can help spread infection by growing from established clusters to uninfected parts. The cords of some wood-rotting fungi (like Serpula lacrymans) may be capable of penetrating masonry. The mechanism of the cord formation is not yet precisely understood.
Fairy rings are detectable by sporocarps (fungal spore pods) in rings or arcs, as well as by a necrotic zone (dead grass), or a ring of dark green grass. Fungus mycelium is present in the ring or arc underneath. The rings may grow to over 10 metres (33 ft) in diameter, and they become stable over time as the fungus grows and seeks food underground.
A ring can be seen on the stem of this Gymnopilus junonius mushroom. An annulus is the ring-like or collar-like structure sometimes found on the stipe of some species of mushrooms . The annulus represents the remnants of the partial veil , after it has ruptured to expose the gills or other spore-producing surface .
White threads of fungal mycelium are sometimes visible underneath leaf litter in a forest floor. A mycorrhizal network (also known as a common mycorrhizal network or CMN ) is an underground network found in forests and other plant communities, created by the hyphae of mycorrhizal fungi joining with plant roots.
Mycelium is an important food source for many soil invertebrates. They are vital to agriculture and are important to almost all species of plants, many species co-evolving with the fungi. Mycelium is a primary factor in some plants' health, nutrient intake and growth, with mycelium being a major factor to plant fitness.
This fungus, like most parasitic fungi, reproduces sexually. The fungi begin life as spores, released into the environment by a mature mushroom. Armillaria ostoyae has a white spore print. There are two mating types for spores (not male and female but similar in effect).
[39] [40] Another devastating fungal pathogen is Sarocladium oryzae, which is a type of sheath rot fungus prevalent in India and is a great threat to rice cultivation. [41] Historically, one of the more well-known cases of plant-fungal pandemics was the potato blight of Ireland, which was caused by a water mold known as Phytophthora infestans .
