68 FUNGUS-FLORA. 



LAQUEARIA. Fries, (figs. 36-38, p. 12.) 



Ascophore innate, flask-shaped, base plane, prolonged 

 upwards into a short neck, which pierces the bark, composed 

 of dark-coloured parenchymatous tissue ; asci clavate, spores 

 8, continuous, hyaline (paraphyses absent ?) 



Laquearia, Fries, Summa Veg. Scand., p. 366 ; Phil., Disc. 

 Brit., p. 372 ; Sacc., Syll., viii. p. 586. 



An imperfectly known genus. I have not seen a British 

 specimen, and have drawn up the characters, generic and 

 specific, from the specimen in Fuckel's Fung. Ehen., exs. 

 n. 2066. I fail to find in the dry specimens that the 

 hypothecium is absent; there appears to be a flask-shaped 

 continuous excipulum perfectly flat at the base owing to 

 being seated on the wood, which is not penetrated, the 

 upper portion elongates into a short thick neck which 

 pierces the bark. When the bark is removed the fungus is 

 carried along with it. 



Laqueria sphaeralis. Fries, Summa Veg. Scand., 

 p. 366 ; Phil. Brit. Disc., p. 372, pi. xi. f. 72 ; Sacc., Syll., 

 n. 2429. (figs. 36-38, p. 12.) 



Ascophore flask-shaped, mouth contracted, entire, blackish- 

 brown, about ^ mm. diameter, asci somewhat clavate, small, 

 spores 8, irregularly biseriate, elliptical, smooth, hyaline, 

 4 x 2 /A ; paraphyses very slender. 



On dry ash branches. Gregarious ; developed under the 

 bark, which is pierced by the narrowed upper portion of the 

 ascophore. 



SCHIZOXYLON. Persoon. (figs. 24-27, p. 22). 



Ascophore subimmersed, spherical at first, apex plane, 

 black, then expanding and exposing the dingy disc ; often pale 

 and furfuraceous or pulverulent outside ; asci cylindrical ; 

 spores 8 filiform, arranged in a parallel fascicle in the ascus, 

 elongated, becoming multi-septate and breaking up into joints 

 at the septa ; paraphyses present.
