Collections Examined

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!).

Habitat

Habit, habitat and distribution.- Solitary or seldom subcespitose, often in fairy rings, in pastures or lawns. Cosmopolitan, undoubtedly introduced to New Zealand.

Notes

Reported from New Zealand by Birch (1937) and Stevenson (1964). Selected Literature.- Antonin & Noordeloos (1993); Gilliam (1976); Singer (1965, 1976).

Collybia subclusilis G. Stev. 1964

Notes

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.

Notes

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

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.
