tion before the spores become reticulated, but distinguished by 

 the much larger cells of the excipulum and smaller spores. 



f Epispore rough. 



Barlaea Crouani. Mass. 



Ascophore i 1 cm. across, fleshy, sessile, urceolate then 

 hemispherical, at length almost plane, externally and the 

 disc dark orange-red or scarlet; margin membranaceous, 

 more or less jagged, spreading or reflexed, whitish ; glabrous, 

 the external large cells of the excipulum giving off stout, 

 colourless, septate hyphae near the base of the ascophore ; 

 asci cylindrical above, attenuated below into a narrow 

 base ; spores 8, uniseriate, globose colourless, uniguttulate, 

 16-18 p. diameter, perfectly smooth for a long time, then 

 furnished with rather strong raised ribs that anastomose to 

 foim an irregularly polygonal network, the meshes averag- 

 ing about 2 //, diameter; paraphyses straight, gradually 

 increasing in thickness from near the base to form a clavate 

 apex 34 p thick, septate, sometimes branched.

Barlaea miniata, Sacc., Syll., n. 416. 



On the ground among tufts of moss, and on the top of 

 walls. 



Cooke's type specimen examined. 



Differs from JB. cinnabarina in the straight, clavate 

 paraphyses. 



Barlaea Wrightii. Sacc., Syll., n. 422. 

 Ascophore about 2 mm. across, sessile, rather fleshy, 

 hemispherical then expanding and becoming almost plane, 

 margin entire, rather thick, every part scarlet, becoming 

 paler when dry; externally minutely papillose, especially 

 when dry, due to unequal contraction of the external cells, 

 otherwise glabrous, cells of epithecium in irregularly 

 parallel rows, much elongated in the direction from base to 

 apex; asci cylindrical, narrowed downwards into a slender
