Descriptions
Marasmius oreades (Bolton) Fr. 1836
Material examined- - NEW ZEALAND: South Island, Prov. Nelson, Nelson, D. Read, 19 IV 1956 (K).- North Island, Prov. Wellington, Wellington, Karori, Stevenson, 15 X 1948 (Holotype of Collybia subclusilis, K!).
Habit, habitat and distribution.- Solitary or seldom subcespitose, often in fairy rings, in pastures or lawns. Cosmopolitan, undoubtedly introduced to New Zealand.
Reported from New Zealand by Birch (1937) and Stevenson (1964). Selected Literature.- Antonin & Noordeloos (1993); Gilliam (1976); Singer (1965, 1976).
Collybia subclusilis Stevenson (29 D) Fig. 25 = Marasmius oreades (Fries) Earle
Spores almond-shaped to sublimoniform, hyaline, neither amyloid nor dextrinoid, smooth, 8-11.5 X 4.5-5.5 µ. This species was probably introduced with seeds (see habitat) and has to be regarded as a synonym of M. oreades.
Marasmius oreades (Bolton) Fr. 1836
We have observed this fungus several times. It has obviously been introduced with seeds, straw or other media. See Collybia subclusilis Stevenson (no. 308).
[Notes from Kew Type specimen, PRJ 2010] Kew images.
Pileus 3-3.5 µm diam., ochraceous buff, hygrophanous, indistinctly striate at margin, matt; flesh concolorous. Gills adnexed to adnate, seceding, creamy, rather distant. Stipe 4-5 cm x 4-5 mm, ochraceous buff, velvety, hollow, tough, equal, rooting at base. Spores 10-11 x 5 µm, non-amyloid, thin-walled, hyaline (Fig. 19). Cuticle of hyphae of large diam., closely woven.
In rough grass, Karori, 15.10.1948, Stevenson (type).
Pileus 3-3.5 µm diam., ochraceo-bubalinus, hygrophanus, margine indistincte striatus, haud lucens; carne concolori. Lamellae adnexae usque adnatae, secendentes, cremeae, subdistantes. Stipes 4-3 cm x 4-5 mm, ochraceo-bubalinus, velutinus, cavus, tenax, aequalis, basi radicante. Sporae 10-11 x 5 µm, haud amyloideae, parietibus tenuibus, hyalinae. Cuticula ex hyphis diametro magnis arcte intertextis sistens.
Typus: Stevenson 459
Marasmius oreades (Bolton) Fr. 1836
This buff-coloured 'fairy-ring' toadstool fairly commonly forms conspicuous rings in pasture. It appears to be parasitic on grass roots and leaves an area of weak grass inside the ring. Nelson, 19.4.1956, D. Read; Hope, 22.4.1956, D. Read; Nelson, 20.4.1957, E. B. Kidson, etc.
