NOTES. 
A NEW GENUS OP TUBERCULAHIEAE. — Hobsonia, Berk., 
in herb. Sporodochia verruciformia, superficialia ; conidia muco iniiio 
immersa, cylindracea, hyalina, in tubum spiraliter laxe convoluta, 
pluriarticulata. 
The present genus was never described by Berkeley, but with the 
above MS. name located in his herbarium amongst the Tremellini, 
with which it agrees superficially in the subgelatinous consistency 
when moist, becoming cartilaginous when dry. The genus, however, 
belongs to the Hyphomycetes, Fam. Tubercularieae, Sect. Helico- 
sporae, and is distinguished by the multiseptate conidia being 
arranged in a lax spiral forming a cylindrical or conical body. Of 
the two genera previously included in the section, Everhartia has 
the conidia multiseptate and spirally wound in one plane, whereas 
in Troposporium the conidia are aseptate and compactly spirally 
wound, forming a cylindrical or fusiform body. 
Named by the late Rev. M. J. Berkeley in honour of Colonel 
Hobson.
