Hitherto not found under any native trees (e.g., Eugenia, 

 Eucalyptus) planted or growing in the neighbourhood. This 

 seems to be the same species that, about twenty years ago, 

 grew in great abundance under Pinus insignis at the Parkside 

 Mental Home. It has died out from this situation for many 

 years, in spite of no alteration having occurred in its sur- 

 roundings. Perhaps the soil became exhausted for it, as is 

 the case in some of the fairy-ring species. The plants have 

 a slight resemblance to the common mushroom, accentuated 

 by the gills having a somewhat flesh-coloured tint, and they 

 have been mistaken for this by persons of little observation. 

 The species is obviously an introduced one, as is evidenced by 

 its clinging to the neighbourhood of introduced trees, but it 

 is remarkable that these should be of several species.
