ACEOSTALAGMUS— CLONOSTACHYS, ool 



Eesembling VerticiUium in habit, distinguislied by the 

 cluster of spores involved in mucus at the tip of each 

 branchlet. By some the spores are considered as being 

 enclosed in a cell, as in Mucm; but it has been shown by 

 Berlese that the apparent membrane consists of mucus that 

 disappears at maturity. 



Acrostalagmus cinnabarinus. Corda. (figs. 6, 7, 

 p. 358.) 



Tufts pulverulent, effused, orange-red or vermilion ; vege- 

 tative hyphae branched, septate ; fertile hyphae erect, rigid, 

 septate, primarj' and secondary branches arranged in whorls, 

 clusters of conidia globose, conidia elliptical, very faintly 

 tinged rose, 3-5 x 1-2 p..

On various decaying vegetable substances. 



CLONOSTACHYS. Corda. (fig. 15a, p. 013.) 



Sterile hyphae creeping, continuous ; fertile, erect, simple, 

 continuous below, septate towards the apex and giving off 

 whorls of brancbes, usually in fours, from the septa; 

 branclilets a^so beaiing whorls of branchlets, usually in 

 ■fours ; branchlets subulate, the upper part densely covered 

 with white, continuous conidia, spirally arranged, and 

 resembling a compact spike.

Clonostacliys araucaria. Corda. (fig. Ioa, p. 313.) 

 Forming-minute white, downy tufts 1—2 line broad and 

 \ a line high ; fei-tile branches erect, simple and without 

 septa for some distance- from the base, septate above, and 

 bearing verticils of branches at the septa, branches aLso 

 verticillately arranged, branches and branchlets in fours ; 

 the branches covered for some distance with closelj- crowded, 

 oblong conidia, the whole resembling a spike ; spikes 

 •crowded, iind forming a compact, elliptical head; conidia 

 5-6x2/1.
