Article: Horak, E. (1973). Fungi Agaricini Novazelandiae I-V. Beihefte zur Nova Hedwigia 43: 200 p. Description: Pileus
3-7 mm diam., obtusely convex becoming plane at the centre and subumbilicate,
striate near the margin, not recurved, deep yellow, glabrous, dry, hygrophanous.
Lamellae (L 8-12,13) broadly adnate to subdecurrent, yellow when young, turning
yellowish-pink, gill edge concolorous, not fimbriate. Stipe 12-25 x 1 mm, cylindrical,
slender, deep yellow, glabrous, dry, stuffed-hollow, solitary. Context yellow.
Odor and taste not distinctive.
Spores
8.5-10 x 6-7 µm, 5-6-angled. Basidia 26-35 x 9 µm, 4-spored. Cheilocystidia
25-50 x 7-9 µm, formed by cylindrical or clavate cells with thin-walled membrane,
sometimes encrusted by pigment, sterile zone at gill edge not conspicuous. Pleuro-
and caulocystidia absent. Cuticle a cutis of repent, cylindrical hyphae (8-12
µm diam.), membrane not gelatinized, encrusted by yellowish pigment. Clamp connections
lacking. Habitat: On soil
under shrubs in forests. New Zealand. Notes: The
small, slender fruitbodies and large spores readily separate this species from
E. sulphureum Hk. Neither has green or olive colours and they are thus
even macroscopically distinguishable from E. chloroxanthum Stev., which
is rather common, whereas the two other species are rare.
Article: Horak, E. (1980). Entoloma (Agaricales) in Indomalaya and Australasia. Beihefte zur Nova Hedwigia 65: 352 p. Habitat: Habitat. - On soil in forests. - New Zealand. Notes: The small (pileus -7 mm diam.) and fragile carpophores and the deep yellow colours are
distinctive for this New Zealand species. The lamellae bear clavate cheilocystidia and the
clampless cuticular hyphae are encrusted with the yellowish pigment. For further
discussion see Horak (1973:61).
