378. Cosmarium Cucumis Ralfs ß helveticum Nordst.

nov. var.

Forma minor, semicellulis apieem versus rapidius attenuatis, in latere
interiore membranae dense scrobiculatis. Long. 48—56 f.i ; lat. 26—36
11; crass. 22—26 lat. isthm. 10—12 ¡.i.

Cosm. subquadrato Nordst. (et C. variolato Lund.) valde affinis
in statu viventi accuratius examinanda est, quum cellulas tantum exsicca-
tas vidi et adeo structura niassse chlorophyllacese mihi in conspectum non
satis evidenter venit.

Forma trigona semicellulis e vertice visis trigonis lateribus rectis,
angulis obtuso-rotundatis immixta est.

Helvetiae ad saxa arenosa humida prope Zürich 18 /tl78
