a vertical section of the unruptured sporangium they may be seen in 

 position, imbedded in the mass of spores. The colored scales upon 

 the surface of the sporangium vary considerably in size in different 



specimens. 



CALICIOPSIS, Gen. nov. 



Receptacle oblong-urceolate or subcylindrical, at first closed, then 

 open and pulverulent at the apex, stipitate. 



A small Caltcmm-Yikfd fungus, which does not well agree with the 

 characters of any genus known to me, has fallen into my hands, and 

 the present genus has been founded upon it. It partakes to some 

 extent of the characters of some of the small substipitate species of 

 Cenaiigium^^ but its more slender habit, long stem and urceolate or 

 subcylindrical receptacle, which soon becomes pulverulent above, 

 separate it from that genus. These same characters and its less 

 tough or corneous substance forbid its reference to the genus 

 Tympanis. 



Caliciopsis pinea. — Scattered or caespitose, about one line high, 

 glabrous, shimng, black; stem slender, straight or curved, slightly 

 thickened at the base, often growing from a cluster of black sphaeri- 

 form perithecia which contain spermatoid bodies; receptacle nar- 

 rowly urceolate, sometimes a little curved or inclined to one side, 

 slightly exceeding the stem in diameter, soon brownish-pulverulent 

 at the apex; asci oval or subeUiptical, long-pedicellate, eight-spored; 



spores crowded, simple, elliptical, colored, .0002-00025 of an inch 

 long.

The pecular form of the receptacle is suggestive of the dry cap- 

 sules of some mosses, particularly of some species of Hypnwn. 

 The sphaeriform bodies and their spermatoid contents are probably 

 only another condition of this fungus. The young stems are at 

 first pointed, but as they increase in length they become more obtuse 

 and finally the apex develops into the receptacle. Although the 

 plant resembles some species of Calicium it is wholly destitute of 

 any thalline crust and gonidial cells, and must be deemed a fungus. 

 The genus should be placed among the Patellariei near Cenangium.
