alveolate condition of the hymenium occurs in Mitrula Rehtnii and 
M. muscicola.

(without a diagnosis); Sacc., Syll. viii, n. 139, 1889; Rehm , Krypt.- 
Flora, n. 5869, 1896. 
Very small, clavate, black, 3-4 mm. long; spores terete-fusoid, 
rounded at both ends, almost straight, 45-50 xio/i, 3-septate, dusky; 
paraphyses moniliform at the apex. 
Hab.—~ Among moss. 
Distr. — Mutters, Tirol. 
Remarkable for the very small size of the ascophore, and the 3-sep- 
tate, thick spores. The above is the diagnosis given by Saccardo 
(Syll. viii, n. 139). 
Spathularxa, Persoon. 
Erect, stipitate ; ascigerous portion obovate, spathulate, or elliptical, 
more or less hollow, laterally compressed, glabrous, decurrent down 
opposite sides of the stem, from which it is sharply differentiated. 
Asci clavate, apex narrowed ; spores 8, arranged in a parallel fascicle 
in the ascus, elongated filiform-clavate, hyaline, multiguttulate then 
multiseptate ; paraphyses present.

Clavaria , Elvella , Mitrula , and Leptoglossum in part, of authors. 
Closely resembling the genus Mitrula in general appearance and 
habit, but in the last-named the spores are much shorter and broader, 
and 2 -seriate in the ascus. The only other genus having very long, 
linear spores arranged in a parallel fascicle in the ascus is Vibrissea , 
but here the ascigerous portion is pileate or horizontal, the margin 
free and incurved ; the upper surface covered with the hymenium, the 
under surface sterile. In Spathularia the ascigerous portion is 
adnate to the stem throughout, and every part is covered with the 
hymenium.
