Calothrix synplocoides P. Reinsch. n. sp. 



Laete aeruginea aut amethysline viridis; fila dena usque duodena (in statu vegeto) 

 in fasces erectos singulos congregata, üla distinctius articulata, integerriina aut rarius 

 ramis singulis instructa, cellularum diameter longitudinalis diamelro transversal! aequalis 

 aut paulo longior, cellularum interanea indistinctius granulosa, laete aeruginea. 



Filorum latitudo 0,009 — 0.^012""; 0,004—0,0052'" rhen. 



In scopulo Keuperiano aqua destillante per lotum annum humido („der tropfende 

 Fels") muscos radicesque dependentes arborura acerosarum frondosarumque tomento 

 aerugineo inducens, in sylva . Sebaldiana (Reichsforst alias dict.) in Franconia.

 densius aut dilutius repleto fructus maturi diametro longitudinali duplo 

 longiore supraque cornulum (antheridlum : Pringsheim) simpliciter aut dupliciter con- 

 volutum insidentes ; fructuum maturorum forma irregulariter sphaerico-ellipsoidea, poli 

 bini diametraliler non oppositi, fructus infima ' pars breviter truncata, fructus summa 

 pars lateraliter breviter rostrata, membrana crassa hyalina ; fructus ante maturitatis Stadium 

 penduli (rostellum deorsuni versum), in maturitatis studio sursum versi (rostellum 

 sursum versum).

Hab. in fossis umbrosis profundiorihus per sylvas ductis vere aqua repletis, auc- 

 tumno aqua vacuis sed humidis sylvae Sebaldianae (Reichsforst) in Franconia; illic 

 lerram arenaceam humidam indumento laete smaragdino inducens.
