additions to tlio knowledge of our flora. Collema and Lep- 

 to(jinm, are ujenerally seen as a Lrownisli-green sort of skin on 

 the bark of many scrul) trees ; on these Ohryznm has been 

 found as a parasite at Ipswich, in Queensland ; on tlie c^round 

 will be found Boiuniyces, and sometimes Oladonia, though tho 

 latter will be more common on logs and rocks ; C. Fhvrldana, 

 and C. marcelenta are easily recognised by their numerous 

 r(;d caps, and 0. 7-etipora by its net-like ap])earance ; all the 

 beard mosses, or Vsnea, will need no description ; they hang 

 from the branches of trees, or on dead wood, fences, etc., 

 in a conspicuous manner. 



Mr, Bailey states that Usuea longissima is extensively used 

 in Queensland, entwined round the hat as a protection 

 against the sun. The common Vsnea on our fences is 

 generally TJ. harhafa, var. cornuta, very common on the Blue 

 Mountains, New South Wales. With this is found llamalina. 

 €omplauata around Brisbane, but it is most abundant on the 

 main ravage. The Siictinas are all of large foliaceous habit, 

 but the close damp gullies of the ranges are the places for 

 them on rocks, logs, and trunks of trees. With these also 

 will be found the genus Sticta. The Pyxine of the accom- 

 panying list, I am informed by Mr. Bailey, was taken from a 

 tree on the coast, near Cairns, Trinity Bay. The Physcian 

 are abundant on the fences, scrubs, trees, and rocks, with the 

 exception of P. cJirysopfhahna, which prefers slender twigs. 

 *' To sec a dead branch covered with this delicate and 

 beautiful species is worth a trip to the scrub at any time." — 

 Bailey. I am indebted to the same gentleman for most of 

 the following facts: — ParDtelia is pretty common every- 

 where. P. tinctornni covers the rails of fences ; P. ptcrforata, 

 loves to grow on charcoal, and thus the l^iu-nt stumps of trees 

 are frecpiently covered with it. Pannaria pannosa is a pretty 

 dark-l)ordered Lichen, found on the bark of trees. On rocks 

 everywhere will be noticed several species of Lecanora, the 

 most attractive of which is L. cinnabevina ; it is a handsome 

 red Lichen, adhering closely to the porphyry rocks ; the 

 thallus is bright green, and the apothecia orange-colored. 

 Pertusaria j^apillafa is found on the bark of trees with 

 Leeidea Domingensis. All the Lichens belonging to the genus 

 Leeidea are more or less attractive, because of the contrast 

 between the thallus and the aj^otliecia. This is particularly 

 the case in L. triplmigma. Graphls is a genus which owes 

 its name to the resemblance between its apothecia and 

 written or angular characters and letters. It occurs in 

 Queensland sometimes in very large patches on the bark 

 of trees. 



It may be necessary to state that all the specimens here
