Fig. 134. — W. H. Brown's diagram illustrating tiio mode of development of 

 a fruit-body of CUutria scufelltifa. The penultimate cell of tlie archicarp 

 has become swollen to form the ascogonium (ascogenous cell) and has 

 given rise to hyphae which are forming the asci. The vegetative liyphae 

 at tlie base of the archicarp have grown in length, have branched, and 

 have produced the paraphyses, the trama, and the outer covering of the 

 fruit-bod v including the setae. 



taining a few granules, and turning green with iodine.^ The spores 

 (Fig. 135) are colourless, smooth, ovoid-elliptic, furnished within 

 with numerous oleaginous granules which fill them completely,

No one has yet grown Ciliaria scuteUata in artificial cultures.

1 E. Boudier. in his Icoties Mijcologicae (Paris, 1905-1910. T. IV, p. 207), by 

 inadvertence, states that the paraphyses turn blue with iodine, but he correctly 

 illustrates them in his Plate CCCVIII as turning green.
