but paler than in Perichaena austvajlis, whose chestnut-coloured 

 sporangia and intense golden spore-mass distinguish it from 

 the present species.

Perichaena australis, Berl. 



Sporangia often circinnate, angular, central ones .orbicular, 

 at first yellow, passing through chestnut to brown, smooth, lid 

 plane ; capillitium yellow ; spores sub-globose, granular within, 

 opaque, yellow.

Perichaena ? pseudaecidium, Speg. 



Sporangia cylindrical, conical, or calyciform, 1 1*5 mm. long, 

 by 0*5 1 mm. broad, sessile or shortly stipitate, wall very thin, 

 cartilagineo-membranaceous, base even or minutely rugulose, 

 dehiscing at the apex in an irregularly laciniate or fimbriate 

 manner, chestnut or brownish; mass of spores and capillitium 

 citrin or yellowish ; capillitium threads very slender, 1 ju, thick, 

 sparingly branched, here and there with solitary conical or elon- 

 gated branch-like spines, yellowish, hyaline; spores globose, 6 7 //, 

 diameter, often irregularly angular from mutual pressure, per- 

 fectly smooth, pale vinous with yellow tinge.

 Tillandsia muscoides.

A very beautiful but paradoxical species exactly resembling 

 a folicolous Aecidium, will probably form the type of a new
