New or Rare Microfungi. A. L. Smith and J. Ramsbottom. 367 



flexuose beak 1050-1200 x 25-30/x; spores ovoid, cylindrical 

 or allantoid, continuous, 3-5-5 x 2-5/a; long, dark brown, septate 

 hairs, 2-3/Lt in diameter, are given off from the base of the pyc- 

 nidia. 



On pine wood, Camberley, Surrey, Aug. 1916. 



The fungus appeared in great quantity on sawn tree stumps, 

 on pine wood and on boxes made from it and not properly dried. 

 The hyphae did not penetrate the wood but the discoloured 

 appearance of the boxes made them unsaleable. 



The description of the fungus given above agrees closely with 

 that by A. Jaczewski in his Monograph of the genus Sphaeronema 

 (Novi Mem. Soc. Imp. Nat. Moscow, xv, p. 330, 1898). Saccardo, 

 Allescher and Diedicke give the spore measurements as included 

 within the limits 3-4 x i-i-5/u,, and the two latter record a 

 smaller size for the pycnidium. In the Camberley specimens 

 spores of this smaller size were obtained several times when the 

 pycnidia were crushed. They always emerged with a mass o : 

 food reserve material: the mature spores escaped through the 

 ostiole.
