lias kindly forwarded us dried specimens of H. appendicu- 

 latum (-FL. candolleanum), from London. The spores of 

 these are distinctly smaller than those of our plants, being 

 6 to 7 x 3'5 to 4 /a, whilst our plants in the dry state have 

 less pale caps and a warm brownish tinge in the gills. The 

 spores of plants identified as H. candolleanum by G. H. 

 Robinson, and given to us by Mr. C. Brittlebank, of Mel- 

 bourne, are distinctly much darker microscopically than 

 those of our plants or Miss Wakefield's. The description and 

 figures given by Peck of H. fragile seem to fit exactly our 

 species. We quote here Peck's description: — "Pileus thin, 

 fragile, conic or subcampanulate, becoming convex, obtuse or 

 subumbonate, floccose-squamulose when young, with the 

 margin slightly appendiculate with fragments of the veil, 

 glabrous when mature, yellowish, greyish or suboehraceous, 

 the centre sometimes a little darker; lamellae thin, narrow, 

 close, adnate, whitish or pallid becoming purplish-brown ; 

 stem slender, stuffed or hollow, glabrous or minutely floccose, 

 white; spores 8 to 10 x 4 to 5 ft." 



Our species (pi. xi., fig. 5) is common in the neighbour- 

 hood of Sydney and at Milson Island, Hawkesbury River, 

 occurring in gardens or on rich soil, sometimes singly and 

 sometimes in large patches. The presence of appendiculate 

 remains of the veil round the edge of the pileus is marked 

 in some specimens, but as a rule is very evanescent. When 

 very young, the plants are convex, pale fawn, margin slightly 

 incurved, showing appendiculate remains of the veil, the 

 surface being covered occasionally with scattered whitish 

 friable warts, also due to the remains of the universal veil. 

 The cap soon expands, remaining somewhat convex and 

 slightly umbonate or being wavy, still showing in some oases 

 scattered punctate granules, and reaches a diameter of 1 to 

 If inches. The centre is brownish-fawn or pallid clay colour, 

 the edge pale fawn, striate. Gills moderately crowded, 

 adnate, whitish then purplish-brown. Stem U to 2 inches 

 high, rather fragile, slender, pure white, silky striate, 

 perhaps slightly mealy above, hollow. Spores purplish-brown, 

 oval, slightly oblique, 6'8 to 9 x 4 to 5'4 /x.

 Hawkesbury River, February to May, November; Hill Top
