pore at the apex, the disc expanding by degrees. Phillips 

 says the spores become 2-3-pseudoseptate ; true septa, 

 however, are not present in the specimens that I have 

 examined from Phillips. 



MoUisia chrysostigma. Mass. 



Grregarious, sessile but attached by a very short, narrovred, 

 stem-like base, pale clear primrose-yellow, sometimes almost 

 white, ^1 mm. across, almost closed at first, then becoming 

 nearly plane, often with a slight trace of down near the 

 margin when expanding, soon quite glabrous ; excipulum 

 parenchymatous, cells irregularly polygonal, running out at 

 the surface and margin into crowded, parallel, obtuse, 

 septate hyphae, yellow at the tip ; asci cylindric-clavate, 

 apex rounded, 8-spored; spores obliquely 1-seriate, cylin- 

 dric-fusiform, hyaline, continuous, smooth, straight or 

 slightly curved, 8-11 x 1'5/i; paraphyses very slender, 

 scarcely thickened at the tips.

Very minute, soft and membranaceous when moist, more 

 or less contracted when dry. 



Cooke's type specimen of P. flaveola examined, also 

 specimens in Cooke, Brit. Fung., ed. ii. n. 550 ; Phil.,

MoUisia versicolor. Phil., Brit. Disc, p. 195. 

 Ascophores scattered, sessile, very minute, rarely exceed- 

 ing ^- mm. across, thin and very delicate, globose, then 

 expanding, glabrous, margin very minutely irregular, white 

 and hyaline, tinged with yellow when dry ; excipulum 

 parenchymatous, cells small and polygonal at the base, 

 becoming elongated upwards, and running out into thin 

 hyphae of variable length to form the irregular margin ; 

 asci clavate, apex rounded, 8-spored ; spores irregularly 

 2-seriate, hyaline, continuous, narrowly elliptic-fusiform, 

 7-10 X 1 • 5 yu, ; paraphyses slender, hyaline.
