Description: Mycena morris-jonesii Stevenson (29 D) Figs 16, 17 = Galactopus morris-jonesii (Stevenson) comb. nov. (Basionym: M. morris-jonesii Stevenson, Kew Bull. 19: 52, 1964)
Spores oval, hyaline, amyloid, smooth, 7.5-9 X 4.5-6 µ. Cheilo- and pleurocystidia fusoid or awl-shaped, thin-walled, coloured with a reddish plasmatic pigment, 50-70 X 10-15 µ.

Article: Segedin, B.P. (1991). Studies in the Agaricales of New Zealand: some Mycena species in sections Longisetae, Polyadelpha, Rubromarginatae, Galactopoda, Lactipedes, and Calodontes. New Zealand Journal of Botany 29(1): 43-62 (http://www.rsnz.org/publish/abstracts.php).
Description: Microscopic characters of the holotype Spores 8-9.5 X 6.5-7.5 (8.6 X 6.8) µm, Q=1.26, 30-35 X 4-8 µm, narrowly fusiform-ventricose to lageniform and often geniculate between the neck and the ventricose portion, forming a fairly dense, tangled layer. Pleurocystidia slightly larger with longer necks than the cheilocystidia. Basidia short and fat with short, fat sterigmata. Trama of more or less parallel hyphae 12-15µm diam., with broad lactifers with yellowish (in KOH) contents, not dextrinoid. Pileipellis of repent hyphae about 3-3.5 µm diam. with short, simple or once-bifurcated, colourless outgrowths. Context of greatly inflated cells (-80 µm diam.) and numerous, conspicuous lactifers with shining, bright golden (in KOH) contents. Subpellis of slightly gelatinised hyphae. Stipe of parallel hyphae, with very conspicuous lactifers with yellow oily contents: the cortical cells are covered with small, simple or once-bifurcated, colourless outgrowths, with occasional terminal cells 10-15 X 2-3 µm, with small protuberances. This is a very tough fungus and sections of the basidiome are very difficult to squash after KOH treatment. The basidiomes are light brown in colour when dried and have a very distinct, small umbo.
Description of basidiome based on information from a further collection
Pileus variable in size from 6-25 mm diam., convex conic with a distinctly pointed umbo, fawn to umber or bay brown at the centre, pellucid striate at the margin, smooth, drying yellow-brown. Lamellae creamy white, drying light yellow-brown, fairly broad, slightly decurrent, in 3 series, margin fimbriate under a lens, not differently coloured. Stipe 20-70 X 2-3 mm, smooth, pale yellow-brown at the top, darker below, even for most of length but slightly expanded at the base. Taste and smell unknown. Basidiome dries light brown with yellowish stipe.
Microscopically PDD 34878 varies little from the type. Spore range, 7-10 X 4.5-7(8.6 X 6.4) µm, Q=1.3, is similar. Some cheilocystidia and pleurocystidia are slightly larger, the pleurocystidia being the larger of the two; both are commonly geniculate at the base of the neck and some at the base of the cystidium. A few very small, slightly diverticulate elements were found on the stipe (Fig. 9,6b).
Habitat: HABITAT: among moss and litter in mixed podocarp-dicotyledonous forest.
Notes: It is unfortunate that no fresh collections of this fungus have been made recently to complement the above description, which is derived from dried material. Stevenson apparently did not see the lactifers in her material and the presence of the many tiny outgrowths from pileipellis and stipe elements persuaded her to classify this fungus in section Rigidipes, subsection Ciliatae. There does not seem any doubt, however, that this fungus should be classified in section Lactipedes.

Article: Stevenson, G. (1964). The Agaricales of New Zealand: V. Kew Bulletin 19(1): 1-59.
Description: Pileus 2-2.5 cm. diam., fawn with brown striations, bay brown at centre, campanulate, umbonate; flesh thin, white to fawn, fragile. Gills sinuately adnexed, creamy white, distant. Stipe 6-7 cm. x 2-3 mm, pale fawn above, bay brown at base, smooth, hollow, fragile. Spores 8 x 6-7 µm, amyloid, thin-walled. Hymenophoral trama and pileus tissue pseudo-amyloid. Cheilo- and pleurocystidia 25-45 x 5-8 µm, more or less awl-shaped; gill margin somewhat gelatinized (Fig. 49).
Habitat: In forest litter, Gollan's Valley. Wellington. 20.5.1949, A. Morris-Jones in Stevenson (type).
