the Fusarium pustules after a few days, only however 

 in the light. If of two cultures whîch had been started at 

 the same time, one was put into the light, and the other 

 wrapped up in black paper, no Fusarium but only Spicaria 

 was formed in the latter. When the black-paper was 

 rcmoved, Fusarium developed in a few days in the culture 

 which had previously been darkened. 



In several ways I tried to obtain a higher fructification ; 

 I made cultures in large flasks and dishes on sterilized 

 bark, wood, bread or liquida; I let some grow very old, 

 put others into the light or kept them in the dark but 

 without any success. In old cultures on cacao-bark I 

 sometimes did flnd small hollow bodies, from which, when 

 pressed, numerous oildrops escaped. As several species of 

 Nectria possess two kinds of conidia: microconidia and a 

 Fusarium, I do not think it unlikely, that in this case 

 too, the higher fructification will prove to be a Nectria, 

 of which the little globules perhaps form the first deve- 

 lopment. 



I hâve named the species Spicaria culoruns, the diagnosis 

 follows hère: 



Spicaria colorans, n. sp. 



Mycélium hyaline, septate, anastomosing; conidiophores 

 hyaline, septate, tapering towards the ends, where the 

 conidia are produced, branched. The branching is irregular, 

 or dichotomous or repeatedly trichotomous. Conidia 

 hyaline, smooth, oval 6 — 10,5 x 4 — 5 /«, formed in long 

 chains at the ends of the conidiophores. The fungus im- 

 parts a violet-red colour to an alkaline médium and partly 

 takes up the colour itself. It often produces a Fusarium. 

 In living cacao bark and wood.
