Agaricus acutus Cooke 1886

On rotten logs. New Zealand (Colenso 48, 88).
Pileo carnoso, conico-campanulato, acuto umbonato, glabro, laevi, opaco, ochraceo (3-5 mm. lat.); stipite gracili, fistuloso (1 unc. long, 1/2 mm. crass.), adpresse fibrilloso, aequali, albido-flavescente ; lamellis adnatis, subconfertis, lutescenti-cinnamomeis, acie pallidiore.
Allied to Agaricus camerinus and Ag. triscopus.

Hypholoma acutum (Cooke) E. Horak 1971

Examination of the well preserved type collection (COLENSO b 48) shows that this distinct species belongs to Hypholoma (Fr.) Kummer and accordingly the combination Hypholoma acutum (Cooke) comb. nov. is proposed.

Hypholoma fasciculare sensu Massee 1899 [1898]

Hypholoma fasciculare (Fries) (1, 16) Fig. 9 = Hypholoma acutum (Cooke) Horak

All characters of this collection (COLENSO b 408) correspond well with the type of H. acutum, a very common species in the forests of New Zealand.

Massee, G.E. 1899: The fungus flora of New Zealand. Transactions and Proceedings of the New Zealand Institute 31: 282–349.

Hypholoma fasciculare sensu Massee 1899 [1898]

Densely clustered, bitter ; pileus bluntly campanulate, then expanded and somewhat umbonate, glabrous, even, tawny, margin yellowish; 2.5-5 cm. across; flesh thin, yellow; gills adnate, crowded, narrow, pale-yellow, then greenish, clouded with the dark spores, inclined to deliquesce at maturity ; spores elliptical, 7 x 4 µ; stem 6-10 cm. long, 4-6 mm. thick, yellow, fibrillose, hollow, often more or less curved.
Northern Island, New Zealand. Australia, Tasmania, Europe, Ceylon, Natal.
On old stumps, &c.
Distinguished by the densely crowded habit, bitter taste, and greenish gills. Poisonous. Flammula inopoda somewhat resembles the present species, but differs in the long rooting base of the stem and the absence of a bitter taste.

Naucoria acuta (Cooke) Sacc. 1887

Pileus fleshy, conico-campanulate, acutely umbonate, glabrous; even, opaque, ochraceous, 3-5 mm. broad ; gills adnate, somewhat crowded, yellowish, then cinnamon, edge paler; spores amber, elliptical, 7-8 x 5 µ; stem slender, hollow, equal, adpressedly fibrillose, yellowish-white, 2.5 cm. long, 1 mm. thick.
New Zealand.
On rotten logs.
A very beautiful little endemic, species, usually densely clustered or gregarious. Pileus somewhat orange-rusty at times. Apparently not uncommon in New Zealand.
