According to Massee ('Brit. Fung. Flora, ii., p. 232, 1893), 

 though "the genus Locellinia, Gillet, founded for the recep- 

 tion of a rusty-spored species having a universal veil that 

 remains at the base of the stem as a volva, differs from Aceta- 

 bularia, Berk., in having a secondary veil and adnate gills, 

 nevertheless Saccardo has made the mistake of sinking 

 Berkeley's genus, and placing the species in Looellinia." 

 Cooke, in his Handbook of Australian Fungi, 1892, follows 

 Saccardo, as does Hennings in Engler and Prantl's Die 

 Naturlichen Pflanzenfamilien. On the other hand, the latter 

 author, under the genus Rozites, Karst., defines this as 

 having a ring on the stem and with the young plant enveloped 

 in a universal veil, which Later on remains as fragments on 

 the surface of the cap and as a sheath at the base of the 

 stem. The Australian plant we have found has when young 

 such a universal veil, rupturing in the way indicated, a 

 marked secondary veil forming later ragged fragments of a 

 ring, and adnate and later nearly free gills. It is obviously 

 Rozites as denned by Hennings, but' also, we take it, the 

 Locellinia of Gillet referred to by Massee. At present we 

 adopt Rozites as being less liable to cause confusion. 



1. Rozites australiensis, n. sp. — The young plant with a 

 subglobose or pear-shaped head up to 3 inches across, on a 

 broad stem 3 inches high and 2| inches broad, which con- 

 tracts into a conical root; adherent to the upper part of the 

 stem and separated from the cap are large ragged fragments 

 •of a universal veil ( = volva) disclosing beneath the secondary 

 veil; viscid when moist; pure white or with a slight brownish 

 tint. When adult, pileus up to 11 inches across, exnanding 

 to convex and then nearly plane and usually broadly gib- 

 bous, sometimes with a depression in the umbo, smooth, white 

 with a slight brownish tint, sometimes cracking, with frag- 

 ments of the veil at the edge. Gills when very young pale
