Laccaria laccata sensu G. Stev. 1964

This usually brick-red species is the commonest toadstool in New Zealand occurring under both native and exotic woody vegetation at all times of the year. Singer (1951) describes the spores as ellipsoid or globose, not more than 10 µm, with spines less than. 1 µm. long. The writer has examined specimens L. laccata in The Kew Herbarium which show the following spore characters:-

(1)     coll. J. E. C. Aberdeen, Queensland, 4.8.1952; spores globose, 8-9 µm diam., spines in, close-set.

(2)     coll. R. W. G. Dennis, Portugal, 16.10.1955; spores ovoid 8-9 x 10-11 µm, spines 0.5 µm.

(3)     Herbarium Berkeley, coll. in Tasmania; spores ovoid 8-9 x 10-11 µm, spines 0.5 µm.

Lange (1935) describes the spores of C. (Laccaria) laccata var. proxima, as ovate-globose, minutely echinulate, 7.5-9 x 6.75-7.5 µm, with spines 1 µm long, but mentions also collections with large globose, spores and comments, probably the form of the spore is not constant; Rea (1922) states that both elliptical and globose spores have been found on the same plant, but this does not seem to have been confirmed and is contrary to the writer's observations.

New Zealand collections which have been examined usually have globose spores, 9-10 µm diam., with well-developed spines, but ovoid spores have also been seen. More information about the distribution of spore forms in relation to macroscopic characters would be interesting.

This mixed description also incorporates L. ohiensis
