40 PETCH : 



272.— Rhinotrichum globiferum B. & Br. 



This species was described, from Thwaites 61 as " Aureum : 

 floccis ramosis, parce articulatis ; sporis sparsis globosis." 



The fungus, in the co*fcype in Herb. Peradeniya, forms 

 effused, thin, lax, velvety, rufous-brown patches. The 

 hyphse are irregularly intertwined, flexuose, yellow-brown, 

 and vary from 7 to 12 [ji in diameter. The distance between 

 the septa is usually from 40 to 60 ij,, and the segments may be 

 either strongly inflated or even. The conidia are borne 

 laterally on short persistent pedicels along the terminal 

 segments, the last segment being sometimes inflated into an 

 ovoid head, about 16 X 14 [x, or on, similar pedicels on short, 

 'elongated, ovoid, lateral branches ; they are globose, yellow- 

 brown, smooth, internally granular, 13-16 \x diameter. 



This is a Physospora, and will stand as Phjsospora globifera 

 (B. & Br.). The hyphse and spores are paler, and have thinner 

 walls, than those of the Ceylon species attributed to Physospora 

 spiralis Penz. & Sacc, and the teiminal segments are shorter 

 and differ in shape. The conidia of the latter species, in 

 Ceylon specimens, are always minutely warted.
