394 FUNGUS-FLORA. 



BAftLAEA. Sacc. 



Ascophore sessile, more or less flesh}', closed at first, then 



Gradually expanding until almost or quite plane, glabrous; 

 isc often brightly coloured ; cortex parenchymatous ; asci 

 cylindrical, 8-spored ; spores globose, hyaline, epispore often 

 ornamented ; paraphyses present. 



Barlaea, Sacc., Syll., viii. p. 111. 



Peziza, of many authors. 



Closely resembling Humaria in size, habit, and general 

 appearance, but readily distinguished by the perfectly 

 globose spores. 



Growing on the ground. 



* Disc red or orange. 

 f Epispore smooth. 



Barlaea constellatio. Sacc., Syll., n. 417. 



Ascophore 2-3 mm. across, sessile, rather fleshy, concave 

 then almost or quite plane, entirely vermilion with a tinge 

 of carmine, margin quite entire, rather thick, similarly 

 coloured; cells of excipulum large, 12-16 p. diameter, 

 glabrous except for the presence of thick, colourless, septate 

 hyphae near the base of the ascophore ; ascus cylindrical 

 above, narrowed below to a narrow, often oblique base; 

 spores 8, globose, hyaline, not usually guttulate, persistently 

 smooth, 11-13 p. diameter; paraphyses cylindrical, curved 

 at the apex, which contains red granules when fresh, about 

 1 5-2 /x. thick. 



Peziza constellatio, B. & Br., Ann. Nat. Hist., n. 1620, 

 ser. 4, vol. xvii. p. 142; Phil., Brit. Disc., p. 86; Cke., 

 Mycogr., fig. 81. 



On the ground ; gregarious but not crowded. 



So far as I have been ablo to ascertain from an examina- 

 tion of the type and other specimens, the spores remain 

 perfectly smooth at maturity.
