TL;DR: Strains from different fruit bodies were somatically compatible when paired on 2% malt agar if sampled from the same ring, but incompatible if from different rings, resulting in mutual antagonism and formation of a persistent demarcation zone.
Abstract: summary
The extension rates of Clitocybe nebularis (Batsch ex Fr.) Kummer strains on 2% malt agar were only 30–40%, of those, up to 3.4 mm d−1, observed in woodland at equivalent exponential mean temperatures. Extension of mature field systems was accomplished by mycelial annuli or arcs 30-40 cm wide, differentiated into a leading edge of mycelial cords followed by a zone of dense, diffuse mycelium which bleached litter components, and a trailing edge of greyish, Used mycelium. Disruption of mature annuli by natural obstacles or experimental re-orientation within the mycelial band resulted in regression of the affected segment of mycelium. Localized lysis following encounter with an obstacle by immature patches of mycelium with a diameter of 30–50 cm, led to polarized development of the residual mycelium.
Strains from different fruit bodies were somatically compatible when paired on 2% malt agar if sampled from the same ring, but incompatible if from different rings, resulting in mutual antagonism and formation of a persistent demarcation zone. By contrast, collision between adjacent systems in woodland culminated in mutual obliteration of the interaction fronts. C nebularis was non-combative when paired against other decomposer basidiomycetes on 2% malt agar, being either replaced or deadlocked but not replacing mycelia of these fungi.
The implications of these observations are discussed in terms of emerging concepts of ecological strategies, foraging theory and polarity in mycelial collectives.

TL;DR: Questions: Does the fairy ring fungus Agaricus campestris affects spatial distribution of co-existing plant species?
Abstract: Questions: Does the fairy ring fungus Agaricus campestris affects spatial distribution of co-existing plant species? Is ring development related to changes of soil physical, chemical, enzymatic and microbiological properties? What are the causes of weakening and subsequent luxuriance of vegetation during fairy ring dynamics in the soil?

TL;DR: In coniferous forests in Japan, especially forests which contain Pinus densiflora, the edible mushroom “matsutake” (T. matsutake) forms fairy rings of fruiting bodies on the ground, which follows the mycorrhizal development of pine rootlets and grows outwards 10–15 cm every year.
Abstract: IN coniferous forests in Japan, especially forests which contain Pinus densiflora, the edible mushroom “matsutake” (T. matsutake) forms fairy rings of fruiting bodies on the ground. The ring follows the mycorrhizal development of pine rootlets and grows outwards 10–15 cm every year. On the inner area of the fairy ring where the mycorrhizas have been decomposed, fruit bodies are seldom formed1,2.

TL;DR: An experimental field with grass had 48 squares which were treated with combinations of NPK fertilizers and a total of 40 species were noted: 36 agarics and 4 gasteromycetes, 5 of which were recorded as fairy ring formers.
Abstract: An experimental field with grass had 48 squares which were treated with combinations of NPK fertilizers. The fungus flora was studied 1978–1980 by numerous yearly observations. A total of 40 species were noted: 36 agarics and 4 gasteromycetes. 24 species were confined to squares where nitrate was applied. 5 of these species were recorded as fairy ring formers. The fairy rings developed exclusively in the +N squares. Some common species grew in both +N and –N squares, while a few species were confined to –N squares. None of the latter group was found in abundance. The squares were divided in parcels sown with 4 species of lawn grasses. Several fungi showed preference for one or two grass species. The field consists of two parts, sown in 1977 and 1972 respectively. The immigration pattern into the new field is described.
