LEOTIA. 471 



continuous or 1-septate, elongated and narrowly elliptical, 

 obliquely 1 2-seriate; paraphyses present. 



Leotia, Hill, Hist. Plant., p. 79 (1751); Phil., Brit. Disc., 

 p. 21 ; Sacc., Syll., viii. p. 609 (in part). 



Distinguished by the pileate, entire receptacle supported 

 on an elongated, central stem, and by the subgelatinous con- 

 sistency of every part. On account of the character last 

 named, the genus is placed in the Bulgaricae by Saccai do ; 

 but the general structure agrees more with the Helvelleae, 

 which includes other species having the same subgelatinous 

 substance, as species of Geoglossum, Vibrissea and Mitrula. 



Growing on the ground, or on decaying wood.
