58 FUNGUS-FLOKA. 



clavate, not much elongated below the spore-bearing por- 

 tion ; spores 8, irregularly biseriate, elliptic- fusoid, straight 

 or curved, often slightly unaequilateral, eguttulate, hyaline, 

 continuous, 22-35 x 7-10 /*; paraphyses numerous, filiform, 

 about 1 /x thick. 



On leaves of Pinus sylvestris. 



This fungus proves very injurious to the Scotch fir in 

 Finland. So far as I am aware, it is very rare in this 

 country ; readily known by the very large spores, which are 

 somewhat variable in shape. 



Specimen examined from Eoumeguere's Fung. Sel., exs., 

 n. 4331, the specimens being furnished by Karsten. 



Phacidium terrestre. Phil., Grev., xviii. p. 86. 



Gregarious, turbinate then discoid with a short stem-like 

 base, 2-3 mm. across, excipulum parenchymatous, brown, 

 finally splitting from the centre into irregular teeth that 

 remain as a border, and exposing the clear but pale primrose- 

 yellow disc ; asci clavate narrowed downwards into a slender 

 pedicel, 8-spored ; spores irregularly 2-seriate above, 1- 

 seriate below, elliptic-oblong, ends obtuse, hyaline, con- 

 tinuous, sometimes guttulate, smooth, 11-13 X 4-5 /x; para- 

 physes slender, the length of the asci, curved and often 

 branched at the tip. 



Podophacidium terrestre, Niessl, Forh. Nat., Band x. (1871), 

 p. 213, t. V , fig. 50. 



On damp ground among decaying leaves, &c. 



Var. humigenum. Ascophore about 3 mm. across, spores 

 26-28 X 6-7 /* ; paraphyses longer than the asci, otherwise 

 as in the type. 



Phacidium humigenum, Cke. & Mass., Grev., vol. xvi. p. 78. 



On damp decaying twigs and leaves lying on the ground. 



Phacidium phacidioides. Mass. 

 Somewhat gregarious, innate, breaking the epidermis into 

 4-5 somewhat equal acute teeth and exposing the disc, which 

 is pale brown when fresh, but becomes darker when dry, up 

 to ^ mm. across ; asci clavate, with an elongated, narrow 

 pedicel, 8-spored; spores narrowly cylindric- fusoid, con- 

 tinuous, hyalline, smooth, straight or slightly curved, 

 18-25 X 4^5 fjL, usually 2 -guttulate, biseriate ; paraphyses
