habitu F. incurvi, sed foliis semilimbatis foliisque minutissime areolatis 
jam toto ccelo diversus. Calyptram non vidi, ex operculi forma autem 
dimidiata erit.”—C. Müll. l. c.

This species, very well figured by La Pylaie as above quoted, 
is, however, incorrectly referred to in his description as being 
figured in pl. 36, in which his Skitophyllum gracile is represented, 
and the references in Bridel and in C. Müller's ‘Synopsis’ are 
both incorrect. Schwegrichen describes the species as his own, 
without any reference to Bridel or to La Pylaie, who had pre- 
ceded him.
