Marasmius druceae G. Stev. 1964

Description (NZ)

[GS] Pileus 1-4.5 Cm- diam pale testaceous, darker at centre, becoming somewhat striate and grooved at margins, plano-convex to plane with a waved margin, velvety; flesh pinkish, tough. Gills adnexed, moderately distant, pinkish fawn, paler at serrulate margins. Stipe 2-4 cm. X 2-4 mm., pale pinkish-buff, velvety, hollow, moderately tough. Spores8 X 4um non-amyloid, thin-walled (Fig. 2/24, p. 37); print white. Cuticle cellular of a faintly pseudo-amyloid palisade overlying woven pseudo-amyloid hyphae 5-8um, diam. HABITAT: on old Cyathea medullaris stump, Wellington Botanic Garden, 26.4.1949, Stevenson (type); on Nothofagus litter, Silverstream, 21.4.1958, H. Druce. [EH] Cuticle of interwoven, cylindrical, partially gelatinised hyphae with clamp connections. Spores comma-like, hyaline, neither amyloid nor dextrinoid, smooth, 7.5-9 X 3.5-4 um Cystidia none. [JAC] stem is pruinose along entire length, stronger at apex and base. The cap has deposits of spores with a partial dextrinoid reaction and some thick-walled, typical of Rhodocollybia (cf JAC12478) and R. purpurata. The latter we know from sequencing has a broad morphology and I believe that is an earlier name, although it posible this represents one of the undescribed Rhodocollybia species. The synonymy with R. purpurata is also supported by at least one of Horak's collections under the name C. drucei which is R. purpurata although that may be a misidentification. Cap a hyaline cutis. Hyphae appear to have thin extra-cellular zebroid hyaline encrustation. Clamps probably present but not seen clearly. Spores length=6.0–7.8µm (µ=7.0, σ=0.56), width=2.8–4.2µm (µ=3.5, σ=0.38), Q=1.7–2.5µm (µ=1.99, σ=0.21), n=20

Pluteus purpuratus G. Stev. 1962

Description

K(M) 235279, Stevenson 881. The collection has been cooked on drying, like much of Stevenson's material. The spores have a retracted and dextrinoid endospore, fully consistent with my recognition of this taxon as Rhodocollybia purpurata.

Description

Marasmius drucei Stevenson (29 D) Fig. 7 = Collybia drucei (Stevenson) comb. nov. (Basionym: M. drucei Stevenson, Kew Bull. 19: 40, 1964)

Cuticle of interwoven, cylindrical, partially gelatinised hyphae with clamp connections. Spores comma-like, hyaline, neither amyloid nor dextrinoid, smooth, 7.5-9 X 3.5-4 µ. Cystidia none.

Lepiotula purpurata (G. Stev.) E. Horak 1971

Description

Pluteus purpuratus Stevenson (26D) Fig. 22 = Lepiotula purpurata (Stevenson) comb. nov. (Basionym: P. purpuratus Stevenson, Kew Bull. 16: 73, 1962)

Spores dextrinoid, indistinctly spurred, smooth, germ pore none, 5.5-6 X 3.5-4 µ. Cheilo- and pleurocystidia not observed (type material in fragmentary condition). The dimensions of the spores given by Stevenson are based on measurements of alien Psathyrella spores. The free gills were obviously the reason for assigning the fungus to Pluteus.

Collections Examined

Material. - New Zealand: Maungatua, 18. IV. 1953, STEVENSON-CONE, 881 (K, holotype).

Habitat

Habitat. - On soil among litter in forests. - New Zealand.

Illustrations

Illustrations. - STEVENSON (1962:1. c.); HORAK (1971; 1980b).

Notes

Remarks. - The pink and free lamellae are probably the reason why STEVENSON identified this species as a member of Pluteus FR. The spores are, however, distinctly dextrinoid and slightly spurred. The basidia are 4-spored, 16-20x4-5 µm. The type material is in rather bad condition and therefore the structure of the cuticle could not be fully revived. By all means cellular elements are absent, and the cylindric hyphae observed are encrusted with grey (KOH) pigment. Clamp connections not observed.
