LX. CRYPTONEMIA gen. nov. 



Frous cellulis interioribus subfiliformibus tenuissimis versus 

 peripheriam in cellulas rotundatas abeuntibus constituta. Fruc- 

 tus duplex? Favellidia intra stratum externmn pustuliformiter 

 inflatum hemisphaericurn , donique apice apertum , in plexu 

 filorum moniliformium anastomosantium nidulantia, glonieru- 

 lum sporarum obovalarum intra perisporium hyalinum foven- 

 tia. Sphcerosporce... Algae a slipite teretiusculo piano* membrana- 

 ceae, ex roseo purpurascentes, saepe proliferae; 



In foliolis exterioribus oriuntur distentione membranaruin 

 epidermidis spatia quasi iridata, superflciem velut pustulis ob- 

 sitam reddentia. Ccllulae filiformes strati medullaris, antea bre- 

 viores, elongantiir, laxiores Hunt, et spatia antea subvacua reti- 

 culo filorum moniliformium anastomosantium implent. In plexu 

 horum filorum et infra epidermidem oritur glomerulus spora- 

 rum, externe filis ambientibus moniliformibus tectus , versus 

 internum, ni fallor. frondis stratum initio spectans , denique 

 poro in superficie frondis orto elabens. Ita conformationem 

 fructus in Cr. lactuca observavi- a structura Phyllophorce ut 

 apparet longc diversam. Cum Kallymenia meo judicio proxime 

 convenit, sed cellulae medullares arctius stipatae et granuloso 

 contentu cellularum illius carent. Favellidia insuper semipro- 

 minenlia, poro aperta, et fila moniliformia anastomosantia inter 

 qua^ uidulantur, genericam distinctionem satis probant. Sub- 

 sLuitia carnosa Kallyinenice , ehartaceo-membranaeea Crypto- 

 neinice.
