Neiiialioii loiigicolle nov. spec. 



Thallus e callo radicali scutato exsurgit, copiose subdichotorne- 

 ramosus, mmis teretibus vel paulum corupressis ad basin non con- 

 strictis. Substantia (in vivo) elastice-gelatinosa, lubrica. Color 

 purpureus, in exsiccatis bene conservatus. 



Cystocarpia singula in mediis fasciculis filorum assimilationis 

 sita. Rami carpogonii terminales, interdum in prolongatione laterali 

 rami principalis nati (Tab. 2). 



This species was growing together with the preceding one 

 which it very much resembled in colour and outer habit. For 

 tliis reason I did not observe when collecting the plant that it was 



different from N. Schrammi 

 and I have therefore unfor- 

 tunately not preserved it in 

 any other form than dried. 

 It was only during the mi- 

 croscopical examination here 

 in Copenhagen that it became 

 clear that my material con- 

 tained two forms and after 

 having arranged them in ac- 

 cordance with the different 

 microscopical characters they 

 also showed quite plainly a 

 difference in the outer habit. 

 Thus the specimens when 

 compared with N. Schrammi 

 were found to be more slender, 

 the thickest branches being 

 5 — 7 mm. thick. They were 

 richly subdichotomously or laterally ramified and the thallus had 

 not the crisp folded surface to be found in N. Schrammi. The 

 colour of the dried specimens was red-brown in contrast to the 

 more dirty yellow-brown in N. Schrammi. 



As to the anatomical structure, this species consists even in 

 the interior of nearly colourless, long-celled, hyphae-like, thick-walled 

 cells running mostly in a vertical direction, interwoven and from 

 3— 14/i thick. Near the periphery they are more richly ramified 

 and bear here the horizontal assimilation-filaments which radiate 

 outwards in small bundles and branch dichotomously (Fig. 4 A). 

 Innermost at the transition from the medullary tissue the cells
