PILEUS: 2-5.5 cm diam., hemispherical when young, convex to plano-convex at maturity, hygrophanous, non-viscid, faintly pellucid-striate at margins when young and wet, not so at maturity and when dry, subglabrous to finely furfuraceous particularly near centre, brick red to reddish brown, drying pallid fawn to buff. Cuticle composed of unspecialised, repent, parallel or slightly interwoven, thin-walled, clamped hyphae 5.5-14 µm diam. LAMELLAE: adnexed to adnate, distant, thick, intermixed, to 1.5 cm deep, flesh pink, glaucous. STIPE: 3-9 cm long, ± equal or slightly tapering apically, 3-6 mm diam., dry, hollow, often contorted, coarsely longitudinally fibrillose giving stipe a silky sheen, reddish brown; flesh concolorous, basal mycelium white. SPORES: spore print white when fresh; spores broadly elliptical, rarely subglobose, often slightly depressed on one side, apiculate, hyaline, inamyloid, finely echinulate, 8-10.5-(12) X 7.5-9.5 µm including spines, spines to 0.7-(l) µm long. HYMENIUM: basidia subclavate to clavate, 32-5 X 8-11 µm, 4-spored, sterigmata to 8 µm long; paraphyses numerous, simple, cylindrical to subclavate or irregular, to 4.5 µm diam., often projecting to base of sterigmata. HYMENOPHORAL TRAMA: regular, composed of tinted, ± parallel, long-celled hyphae; clamp connections present. CONTEXT OF PILEUS: thin, reddish brown. SMELL AND TASTE: not distinctive. CHEMICAL CHARACTERS : FeSO4 on pileus and context—rapidly dark grey; KOH and NH4OH on pileus and context—n.r.
Gregarious to caespitose under introduced conifers.

The epithet proxima has usually been applied to a species closely resembling Laccaria laccata but of larger stature, with mainly elliptical spores less than 10 µm in longest dimension, and with spines to 1 µm long. However, Singer (1967) published a different interpretation of L. proxima based on a collection from the French Jura. He regards it as a species with rather coarsely echinulate, elliptical spores (10)-l 1-12.8 X 7.5-9.5 µm including spines, spines (1.2)-1.5-(2) µm long, and possessing numerous filamentous or subclavate paraphyses. Singer's interpretation of L. proxima agrees closely with the protologue in macroscopic characters, but it should be noted that Boudier described the spores of his fungus as finely and shortly echinulate. The fungus with smaller, finely echinulate spores, usually described under L. proxima, was regarded by Singer (1967) as possibly a large form of L. laccata var. laccata. New Zealand collections agree closely with Singer's interpretation of L. proxima, except that the spore ornamentation is slightly shorter.

L. proxima is an introduced species and has been found only in association with exotic conifers. It is characterised by the large stature, reddish brown pileus and stipe, and broadly elliptical spores. The species has not previously been recorded from New Zealand.

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
