44. ! P. (D.) ancilis Pers. (Grevillea XVII., 1888, p. 44). 



"On marshy soil full of sawdust, April ! Substipitate, fragile, externally 

 white, with thick branching veins below ; hymenium at first concave, 

 becoming nearly plain and wrinkled, greyish or purplish brown ; asci 

 cylindrical, narrowed below ; sporidia 8, broadly fusiform, with an 

 apiculus at each end, 3-guttulate, brownish, 25-29 by 10-12; para- 

 physes stout, a little enlarged at the brownish summits, indistinctly 

 septate. 



Cups 25 75 mm. broad, 10-35 mrn « high." 



Bee (Tyrebagger Hill, near Aberdeen, April, 18S8 ! ) 



45. P. (D.) umbrina Boud. (Phillips in Grevillea, XVII., p. 44). 



On charred wood, September, 1888. 

 " Caespitose, sessile, large, at first hemispherical, then expanded, 

 margin persistently incurved, externally pruinose, or granulose, pale 

 brown ; hymenium umber brown ; asci cylindrical, narrowed near 

 the base ; sporidia 8, elliptic, asperate, hyaline, (18-20 by 9, Cooke), 

 I 3" I 5 by 7 ; paraphyses filiform, a little enlarged at the summits. 

 Cups 2 to 3 inches broad. The exterior in the specimens from Scotland 

 was granulose rather than pruinose, and the sporidia were rather 

 smaller than Dr. Cooke's measurements, but I have no doubt it is 

 Boudier's species.
