112 NOTES AND ADDITIONS TO THE FUNGUS FLOKA, 



Apparently near Hydnangium hrishanensis, diflfer- 

 ing mainly in colour and density of gieba. 



Hydnangium densum, n.s. Globose, pale ochre, 



1 cm. diameter. Peridium very thick and tough. Gleba 

 marbled with black from the small spore cavities which 

 are about 0.3 mm. diameter and densely packed with 

 spores. Spores globose, brown, minutely echinulate, 



Mt. Nelson Range. 



A very curious species. In section the thick peri- 

 dium and black spore cavities and general dense struc- 

 ture differ from other members of the genus. 



Hydnangium alveolatuiii, C. et M. Subglobose, palb 

 ochre, 5-10 cm. diameter. Peridium thin fleshy, gleba 

 dense, cells pale ochre numerous, about 0-2 mm. dia- 

 meter, densei; spores globose, minutely alveolate, 10-12 

 11. diameter. 



Valley at foot of Mt. Wellington. 



Hysterangium atratum, n.s Subglobose, 1.5-2 cm. 

 diameter, dark brown, viscid. Peridium fleshy, tough,, 

 thin; gleba dark brown, canals small but very numer- 

 ous. Spores dark brown, nearly globose 12 x 11 

 fx,^ minutely alveolate. 



Very like H. negJectum, but with very different 

 spores. 



Mt. Nelson Range. 



Hysterangium ohtusum, n.s. Irregularly globose 



2 cm., violet when fresh. Peridium thick violet not 

 easily se.parati;ig from the gleba. Gleba pale slatey 

 olive. Spores oblong, very obtuse, smooth, hyaline, & 

 X 4 /i. 



Differing from thei H . affine in peridium and spores. 

 Mt. Nelson Range. 



Hymenogaster fulvus is described in P. et P. R.S> 

 Tas., 1917, p. 109, as being black. It becomes so when 

 old, but is pale gray when young. 



tSecotium ochraceum, n.s. Underground sub- 

 globose, 1-2 cm. diameter. Pale ochre-brown, sur- 

 face verrucose, peridium very thin, hardly appa,rent; 

 stem short, extending to the upper surface, but not 

 produced laterally on the pileus. Gleba ochraceous, 

 canals bold tortuous, dissepiments thin. Spores elliptic, 

 subacute at both ends, pale-brown, smooth, 16 x 8 ^u. 



Very like forms of S. gunnii, but spores twice as 

 long. 



Cascades, Hobart.
