Astrosporina scissa E. Horak 1978 [1977]
New Zealand: "Westcoast, Kopara; 18.1.1968, leg. Horak" (PDD, 27113: holotype; ZT, 68/40: isotype). "Westcoast, Ahaura, Granite Creek; 17.X11.1967, leg. Horak" (ZT, 67/272). "Nelson, Lake Rotoiti; 20.1.1969, leg. Horak" (ZT, 69/1).
Pileus -40 mm diam., conical at first, soon convex to plane with distinct and permanent umbo; straw-yellow, ochraceous or yellow-beige, more intensive at centre; smooth at umbo, fibrillose and rimose towards the margin, conspicuously splitting, crenate (like B. vitellinus), seen from above like spokes of a wheel; viscid when wet, veil remnants absent. Lamellae adnate to almost free, ventricose, crowded (L 18-24, 1 3); whitish, grey later turning brownish beige with white, fimbriate edges. Stipe 20-50 x 3-4 mm, cylindrical, equal, base marginate bulbous; white later turning (yellowish) brownish with pink or reddish tints; pruinate for whole length, sometimes longitudinally striate; dry, veil remnants none. Context yellow beneath cuticle, brownish pink in stipe, Odour not distinctive.
Spores 8-11 x 5.5-8 pm, nodulose, with conspicuous knobs, brown. Basidia 22-32 x 7-8 ^m, 4-spored. Cheilocystidia and pleurocystidia 35-65 x 20-34 µm, broadly inflated-fusoid, pear shaped, metuloid, encrusted, yellowish plasmatic pigment. Caulo-cystidia like cheilocystidia. Cuticle a cutis of cylindrical hyphae (4-10 µm), encrusted with brown-yellow pigment, slightly gelatinised membranes. Clamp connections present.

On soil in Nothofagus forests (N. cliffortioides, N. fusca; rarely under Leptospermum scoparium). New Zealand.
Pileo -40 mm lato, umbonato-convexo, umbonato-plano, stramineo vel ochraceo, fibrilloso, marginem versus rimoso-fissurato, velo nullo. Lamellis ex adnato subliberis. Stipite -50 x -4 mm, cylindraceo, ad basim marginato-bulboso, albido dein carneolo, pruinoso, sicco. 0do:e nullo. Sporis 8-11 X 5.5-8 µm, nodulosis. Cystidiis ovato-inflatis, metuloideis, incrustatis, luteolis. Habitatio ad terram in silvis nothofagineis. Nova Zeiandia. Typus (PDD, 27113).
This spectacular Astrosporina is recognised by the deeply split margin and the metuloid, subglobose cheilo- and pleurocystidia. Macroscopically the New Zealand species resembles I. discissa del. (Cleland 1934) but the cheilocystidia of this species are cylindrical and thin-walled and the context emits a strong spermatic smell.
