CYTISPORA. 



[ 187 ] 



DACRYMYCES. 



pie, setigerous, but without a tuft or pencil 

 of long filaments ; inferior antennae with one 

 tolerably long, curved and three-jointed fila- 

 ment; feet three pairs, none enclosed within 

 the shell; abdomen short; last four joints 

 of superior antennas with one or two setae at 

 the base, the last terminated by several ra- 

 ther larger hairs ; inferior antennas with five 

 joints ; feet five-jointed, second joint largest, 

 the last terminated by one or two long curved 

 hooks directed forwards. 



Fifteen'British species, all marine but one, 

 viz. 



C. inopinator (PI. 15. fig. 26). Shell ob- 

 long-ovate, nearly of equal size at each end, 

 white, with a slightly orange mark on the 

 upper edge, transparent, smooth and shining, 

 with a few short spinous projections on the 

 lower margin of the posterior extremity; 

 each valve with a gibbous external projection 

 at about the middle; superior antennae 

 five(?)-jointed, and with rather short setae ; 

 size, "very small" ! 



BIBL. Baird, Brit. Entomostraca, p. 163. 



CYTHEREIS, Jones. A genus of Ento- 

 mostraca. 



Char. Animals unknown. Valves of the 

 carapace almost regularly oblong; surface 

 very irregular, being wrinkled, ridged, and 

 beset with tubercles, andcrenulated or strongly 

 toothed on the margins. 



Three British species. Found in sea- 

 sand. 



Do they consist of valves of Entomostraca 

 partially converted into calcareous crystal- 

 loids, or upon which crystalloids are depo- 

 sited ?

CYTISPORA, Ehrenb. A genus of Me- 

 lauconiacei (Coniomycetous Fungi), remark- 

 able for emitting the minute bodies formerly 

 regarded as spores, agglutinated together 

 into a more or less gelatinous mass, in the 

 form of a tendril. The relationship between 

 the forms called Cytispora and various spe- 

 cies of Sphferia has long been noticed, and 

 Fries stated that he had seen C. leucostoma 

 pass into S. leucostoma. C.fugax was stated 

 by Berkeley to be exactly analogous to S. sa~ 

 licina. Recent researches seem to prove 

 that the present genus, with Septoria and 

 others, are really only forms belonging to 

 various Ascomycetous Fungi, and that they 

 bear the same relationship to the latter as 

 the spermagonia of LICHENS do to the the- 

 ciferous fructification. Hence the so-called 

 spores of Cytispora, &c. would in reality be 

 the spermatia or stylospores of the Sphcerice. 



As these questions are not yet clearly worked 

 out, we retain the names of these pseudo- 

 genera and species in the present work. 

 More minute details on the subject are given 

 under SPH^RIA, and the works of Tulasne 

 and Messrs. Berkeley and Broome below 

 cited should be consulted. 



1. Cytispora rubescens, Fr. Disk dirty 

 brown; spores (?) reddish. On Rosaceae.

DACRYMYCES, Fries. A genus of Tre- 

 mellini (Hymenomycetous Fungi), consisting 

 of lobulated gelatinous bodies growing upon 

 wood. D. stillatus, a common species, is 

 yellow or red, turning brown when dried. 

 Tulasne has recently published some curious 

 observations on this genus, showing that the 

 spores produced on the basidia of the exter- 

 nal hymenial layer, are of two kinds, and
