On dry birch twigs. 



The Hendersonia referred to this species by Tulasne is referred by Currey 

 to Diatrypelanciforrais, Fr. (See p. 436, ante.) 



Entirely concealed by the cuticle, scattered; perithecia depressed collapsed, 

 dall, as if very minutely palvernlent ; ostiolum minute ; asci clavate, large ; 

 sporidia biseriate, oblong, slightly curved when seen laterally, at first con- 

 sisting of two joints ; these soon acquire seven endochromes, of which four 

 belong to the larger division, at a later period they become much darker, and 

 true septa are formed varying in number from five to six. Till they ac- 

 quire this dark tint they have a thick pellucid gelatinous coat. — B. 4" -Br.

AscoPHORE. — Scattered; perithecia immersed, depresso-glo-

On dead branches of elm. 



Scattered, scarcely visible externally ; asci large, clavate, paraphyses flex- 

 uous ; sporidia large, at first hyaline, consisting of two subconical articula- 

 tions placed base to base, one of these gradually increases in diameter and 

 becomes very obtuse, a septum is then formed at the base of the smaller ar- 

 ticulation, and sometimes, though rarely, there is a third septum in the 

 other c^'lls. In every stage, except in extreme age, when ejected they have a 

 gelatinous coat. Distinguished from M. inquiruuis by the peculiar form of 

 the sporidia, and especially in their mode of formation.— B. q Br.

AscoPHORE. — Scattered; perithecia covered, orbicular, con- 

 centrically striate, black ; orifice when stripped of the epidermis 

 whitish ; papilla yellowish; sporidia oblong, straight, rarely 

 curved, obtuse, divided by a septum into two unequal parts — the 

 upper trilocular, the lower bilocular. — Tul. Carp. ii. p. 225.
