152 THE VICTORIAN NATURALIST. 



The antheridege may be found mixed with club-shaped para- 

 physes. The cellulation of the leaves is comparatively open. 



After a little more climbing we came across the little lichen 

 Bceomyces heteromorjjfms on a clayey bank ; it very much 

 resembles a minute mushroom with a rose-pink head. This 

 plant may be easily passed over as a fungus, but it is a true lichen, 

 with minute simple spores, which may be seen by reducing the 

 head to powder on a glass slip with water ; it should then be 

 examined with a ^-inch objective; the spores are beautifully 

 regular, and are about .01 x .006 millimetres in size. The whole 

 plant is not more than a quarter of an inch in height. 



We afterwards collected some good specimens of Hypnoden- 

 dron s'pininervum in fine fruit and about three inches high. 

 This moss is not unlike a miniature palm-tree, but with the fruit 

 rising above the plant on long setee or fruit-stalks. The branches 

 and the fruit are disposed very gracefully, and make beautiful 

 specimens when neatly laid out. The leaves are deeply serrated, 

 both on the margins and on the back, and are consequently 

 easily identified. 



On examining an old log at the top of the Gully we found 

 Camjiylopus intrqflexus in the interstices ; it was in excellent 

 fruit. This moss is specifically named in allusion to the bent 

 fruit-stalk, and there cannot be a more charming object for dark- 

 ground illumination if well mounted in glycerine jelly. The form 

 of the capsule is perfect, and the calyptra (enclosing veil) is 

 exquisitely fringed. Unfortunately no other plant has, I think, 

 so many synonyms as this. 



Another moss, Acanthocladium extenuatum, was also plentiful, 

 with its peculiar pale green shining leaves, each leaf with a long 

 piliferous point as long as the leaf itself. This will always be 

 remembered when once seen. It forms large light green patches 

 on the old logs. 



Many beautiful Hepaticse have been collected in this gully, but 

 the disastrous fire eight or nine years ago appears to have nearly 

 exterminated them. 



In addition to the foregoing we found the following plants : — 



Mosses. — Rhizogonium spiniforme, Macromitrium erosulum, 

 Polytrichum undulatum, Bryum pseudo-pallescens, Hookeria 

 rotundifolia, Porotrichum cochlearifolium, Meteorium flexicaule, 

 Pogonatum tortile, Thuidium furfurosum, Fissidens, sp. 



Hepatics. — Chiloscyphus laxus, Marchantia polymorpha. 



Lichens. — Parmelia tenuirima, Biatoriopsis lutea, Peltigera 

 polydactyla, Stictina crocata, Trypothelium fumosa-cinerea, 

 Thelotrema lepadina. 



On reaching the refreshment-house above the head of the Gully 

 we rested awhile, and then paid a visit to the new look-out tower 

 recently erected by the Government on the summit of One Tree
