T. mucronatam nostram cum C. ripario comparantes, videre 

 etenim possumus omni respectu diversos esse hos muscos. Ab 

 hoc illa, si quidem differentias jam antea datas praetereamus, 

 differt inflorescentia feminea semper acrogena; colore obscuro, 

 viridi; ramis paucis fastigiatis; foliis (eisdera T. muralis et forma 

 et strußtufa valde similibus) minoribus, sublaxis, statu sicco tortis, 

 e basi cequali linguceformibus, apice rotundato-obtusis , interdum 

 subemarginatis , distincte carinatis, nervo crassiore et teretiore, 

 dorso magis prominente, ut mucrone breve excedente, margine in/ra 

 valde revoluto et divergente, supra adpresso et minus revoluto, a 

 duobus stratis cellularum incrassato, cellulis baseos maximis, laxis, 

 rectangularibus, hyalino-pellucidis , haad incrassatis, superioribus 

 minimis, valde indistinctis , quadratis, dorso papillosis, eisdem 

 marginalibus ceteris simillimis; celhdis operculi elongate rectangu- 

 laribus, omnibus in seriebus dextrorsum spiraliter tortis dispositis. 

 ■ — ■ Notae distinctivae C. ripaiii, cujus forma T. mucronata in 

 Bryol. eur. false dicitur, sunt: inflorescentia feminea et clado- 

 et acrogena; color luridus, nigrescens, inferne nitidus; caulis sub- 

 dichotomus, folia majora, sicca stricta et aclpressa, e basi angusti- 

 ore oblong o-lanceolata, obtasiuscula, fere omnino plana, margo planus, 

 toto ambitu e duobus stratis, a Iribus vel quatuor seriebus cellu- 

 larum formatis, incrassatus, nervus tenuior et dorso minus promi- 

 nens, in summo apice dissolutus, cellulw (eisdem C. aquatici et 

 minoris simillimse) basilares paullo majores, subquadratce, distincte 

 incrassato}, vix hyalince, saperiores rotundatce, quadri — sexangidce, 

 omnino leeves, parietibus evidentissime incrassatis et hyalino-pellu- 

 cidis, ecedem marginales majores, magis chlor ophyllif er m et incras- 

 sato, inferiores rectangulares, superi ores quadratce; cellulce operculi 

 elongate rectangidares, basilares in spiram dextram parum nutantem
