260 THE president's address. 



VI. Sjyumatoria longicoUis, Mass & Salm. A member of the 

 Pyrenomycetes, hitherto met with only on dung. 1, 

 Plants, natural size. 2, A single plant, highly magni- 

 fied ; the perithecium or globose portion containing the 

 spores is more or less immersed in the matrix ; the neck, 

 up which the spores have to pass to escape, protrudes. 

 Conidia (3) are first produced ; these when mature 

 pass up the long neck, and being mixed with mucus, 

 form a sticky ball at the apex, being held in position 

 by bristles. Afterwards spores produced in asci develop 

 ill the perithecium, and eventually form a glairy ball 

 at the apex. The masses of conidia and spores are 

 eventually diffiised by rain or eaten by minute animals, 

 mites, podurae, etc.
