The preceding species are all similar in many features, but the 

 following is so different in shape and arrangement of the pores that 

 a "new genus" has on two occasions been suggested, but not proposed. 



CYTTARIA HOOKERII (Fig. 996). This little species was 

 named and figured by Berkeley from Cape Horn in 1847. We repro- 

 duce the figure, also a section (Fig. 997). 

 We think the figure is so characteristic, 

 there can be no trouble in recognizing the 

 plant, although his description calls for 

 "cups" and the figure does not show 

 "cups," but cavities. The plant is evident- 

 ly very abundant at Cape Horn and so 

 reported by both Hariot and Spegazzini. 

 The latter states that the "loculi" are first 

 closed then lacerate, dehiscent. He de- 

 scribes the spores as elliptical, 10 x 15 mic. and the color of the fresh 

 plant as yellowish cinnamon. 



Synonyms. Cyttaria Purdiei, figured by Buchanan from Xew Zealand, is surely Cyttaria 

 Gunnii. 



Cyttaria Reichei from Chile, as figured and described by Hennings, was based evidently on 

 a large specimen of Cyttaria Darwinii. 



Cyttaria disciformis, named by Leveille from Chile, is said to be not a Cyttaria, though if any- 

 one knows what it is he has not stated. 



RESUME. We present below photographs of the three species we have in 

 our museum, which show at a glance the difference on which they are based. 



Fig. 998 is Cyttaria Espinosae, Fig. 999 is Cyttaria Gunnii, and Fig. 1000 is 

 Cyttaria Darwinii. The following appear to be the principal facts as to the genus, 

 as far as known. It occurs only in Xew Zealand, Tasmania and southern South 

 America. It grows only on the native beech or Xothofagus as now classed. Two

species, viz., Darwinii and Hookerii, are common at Cape Horn. Berteroi is rare 

 there, and Espinosae is known only from further north (Santiago). Cyttaria Gunnii 

 only occurs in Xew Zealand and Tasmania. 



We hope this article may interest others and lead to additional specimens 

 and information. Simply dry the specimens. It is an unnecessary expense and 

 trouble to send in formalin and in most cases useless, as they usually disintegrate 

 into an amorphous mass before reaching me. Dried specimens can be soaked, and 

 will resume their original size, shape and characters.
