loped, althoug S t r 6 m f e 1 1 (]. c.) says tbat the were ma. 

 ture. In the typical form of L. Lenormandi the sporangia 

 often have been found bisporic, but mature sporangia are> 

 according to S t r 6 m f e 1 1, always tetrasporic. At Skorpen 

 I also found a couple of specimens provided with concep- 

 tacles of sporocarps on the same individual bearing sporan- 

 gia, and a specimen forming a transiti on to the typical form 

 only bearing conceptacles of sporocarps. The latter are co- 

 nical, more or less acute, 400— -800 [x in diameter at the 

 base and when mature upwards traversed by a canal. The 

 sporocarpia are large but much varying, pearshaped or pro- 

 bably more often ovate or subglobose, 110 — 210 \k long and 

 75—115 (i thick.

Descr. Harvcyella mirabilis Rke. 1. c. 



This plant has been found in small number on Bhodo- 

 mela sub f us ca at Svinor in the neighbourhood of Lindesnes. 



I brougth home from Kjelmd in East-Finmarken some 

 specimens of a small and somewhat stunted form oiDumon- 

 tia filiformis infested by a parasitic alga much resembling a 

 Choreocolax or Harveyella which I formerly have overlooked. 

 It is, however, steril bo that it cannot be determined with 

 certainty. I sent a specimen to Prof. .Fr. Schmitz, who 

 has had the kindness to communicate to me, that it seems 

 to belong either to Choreocolax PolysipJwniæ or Harveyella 

 mirabilis.

I have not had the opportunity of seing Ruprechfs 

 description of this species. According to Kjellman 1. c. 

 it differs from P. cruenta, to which it is most nearly reia-
