FUNGU8-BLIGHT8 OP QUEENSLAND. 391 



Under the heading of Parasites will be found enumerated 

 all those kinds which prey upon the vitals of the plants they 

 attack. It is difficult, however, to draw a hard-and-fast rule 

 in the matter, and it is not improbable that some species 

 placed in this section should have been given in the first, 



EPIPHYTES. 



Aktemnaria Robinsonii, Berk, and Mont — This soot- 

 like blight, which we are told infests ferns in the Island of 

 Juan Fernan'dez, was a few years ago very thick on plants 

 of Baccharis lialimifolia in the Brisbane gardens. A. serai- 

 ovata, B. and Br., so common on ferns in England, is often 

 abundant on a variety of garden shrubs. 



AsTERiNA ALSOPHiLiE, Cke. and Mass. — Found on the 

 fronds of a fern tree, Alsophila rehecccB. A. Baileyi, B. and 

 Br. is met with on the foliage of Hakea Inrea and other 

 shrubs; A. epixera, B. and Br., on leaves of Mallotus 

 philippinensis, near Brisbane ; A. pelliculosa. Berk., on the 

 leaves of Trema asjjera in mountain scrubs, Queensland. It 

 is also met with in Cuba, North America, and Ceylon ; A. 

 platystoma, Che. and Mass., very abundant at times on the 

 foliage of the bean-tree, Casta7wspermum aitstrale, near Bris- 

 bane ; A. reptans. Berk, and Curt. — In Cuba this species was 

 found on the leaves of a Piper. In Queensland it was met 

 with at the Russell River on a Eut/enia. 



AsTEROMELLA EPiTREMA, Cooke, infests the foliage of 

 lYema aspera growing in monntsim scrubs. A. homalanthi, 

 C. and M., is injurious to the foliage of Homala7ithus popu- 

 lif alius. 



Capnodiastrum orbiculatum, Cke. and Mass. — This 

 forms black cushion-like heaps on the foliage of the native 

 shrubs in tropical Queensland, near the base of the Bellenden 

 Ker range. So far as at present known this is its only 

 habitat. 



Capnodium AU8TRALE, Mont. — This sooty blight is said to 

 have been first found on the branchlets of Swan River 

 conifers. It is also found on plants of the same order in 

 Europe. In the Brisbane Botanic Gardens a few years ago 

 it might be seen clothing, with its black felt, some large 

 plants of cycas, completely concealing every particle of the 

 green plant. C. elongatum. Berk, and Desm. — This species 

 often makes a rank growth on the twigs of plants, especially 

 an those infested by scaly -bugs. Besides Queensland and
