     Dear Marco
     I don't have access to the original 1855 description but I will see if 
     I can get hold of it. In the meantime the following might be useful.
     Coprinus colensoi Berkeley, in Hooker, Flora Novae-Zealandiae, vol. 2, 
     p.175, 1855. Also Hooker, Hanbook of the New Zealand Flora, p.604, 
     Massee, G. 1898. The fungus flora of New Zealand. Transactions and 
     Proceedings of the New Zealand Institute 31: 282-349 + plates 
     Page 292 "Coprinus colensoi, Berk., Flora N.Z.  ii., p.175; Hdbk. N.Z. 
     Flora, p.604; Sacc., Syll. v., no.  .
     Pileus cylindrical, obtuse, then companulate, very thin, covered with 
     snow-white scurfy meal, below the meal greyish and slightly striate, 
     1/2-3/4 cm. high; gills narrow, black; spores blackish-brown, 
     elliptic-oblong, 0.7 mu long; stem 1.5-4 cm. long, slender, tomentose, 
     On dung; subfasciculate. Northern Island, New Zealand.
     A pretty little endemic species, allied to Coprinus niveus, bur 
     smaller, and the pileus not so cottony in its covering veil."

     Page 413. "Coprinus colensoi Berkeley. The type specimen (Berkeley 
     5293) is well prreserved. The spores of this small Coprinus, only 1-2 
     cm high, measure 7-8 x 3.5-4 mu and have a broad apical germ-pore. The 
     globular cells of the veil (20-50 mu diam.) on top of the pileus are 
     densely but minutely warted. These peculiarities put C.colensoi into 
     sect. Vestii (Lange) Kuhner and Romagnesi." Fig 4/61, a, b & c, p.414, 
     depict carpophores, spores, cuticle.
     Note "Berkeley 5293" held at Kew.
