Erionema Penzig 



1898. Erionema Penzig, Die Myx. d. Fl. v. Beutenzorg, p. 36. 



Sporangia plasmodiocarpous but distinct, cylindrical ; capillitium 

 intricate, elastic; nodules few. 



1. Erionema aureum Penzig 



1898. Erionema aureum Penz. /. c. 



Sporangia elongate, clustered, pendulous, yellow or grayish yellow, 

 generally stipitate on long flaccid stalks, or sessile and interlacing: 

 stipes yellow, blending with the hypothallus ; capillitium intricate, 

 expanding at maturity after the manner of Arcyria to several times 

 the sporangial length, the nodules small, yellow ; spores nearly smooth, 

 violaceous-brown, 5-6 /u.. 



This unique form is near the fuligos which it resembles, especially 

 when sessile, in its intricate sporangia. The spores also are those of 

 the common Fuligo septica. The habit is however entirely different. 

 Mr. Fetch describes clusters in Ceylon, hanging free, four to six cm. 

 in length!

Sporangia simple; peridial wall simple, thin, breaking irregularly; 

 capillitium formed of abundant, richly anastomosing tubules, filled 

 throughout their entire length with calcareous granules; the nodes 

 often feebly represented; stipe poorly developed or wanting entirely; 

 columella, except in forms sometimes assigned to the sub-genus 

 Scyphiujn, poorly developed or none; spores frequently adherent in 

 clusters. 



This genus is closely related to Physarum, but differs in having the 



The whole genus calls for careful and protracted study; and the present 

 so-called species are like something new on the world; as full of vagaries as 

 though but just entered upon their phylogenetic race.
