Verticillium epimyces, B. & Br., Ann. Nat. Hist., n. 533, 

 t. vii. f. 15 ; Sacc., Syll., iv. n. 798. 

 On various species of decaying fungi. 



Verticillium buxi. Aners. & Fleisch. 



Forming effused, minutely pulverulent, very pale rose- 

 coloured tufts; sterile hyphae creeping, interlaced; fertile 

 erect, main branches short, in opposite pairs or whorls of 

 three, secondary branchlets similarly arranged ; conidia 

 elliptic-oblong, with a faint rosy tinge when mature, 

 6-10 x 3-4 fji. 



Verticillium buxi, Aners. & Fleisch. in Hedwigia, 18G7, 

 p. 9 ; Sacc., Syll., iv. n. 800. 



Not Penicillium roseum, Cooke, as stated by Saccardo. 



On the under surface of fading and dead box leaves. 



Verticillium lateritium. Berk. 



Forming broadly eifused velvety orange-red or vermilion- 

 coloured patches; sterile hyphae dense, creeping septate, 

 fertile erect, primary and secondary branches in verticils, 

 the whorls becoming smaller upwards, giving the whole a 

 pyramidal outline; conidia, like the hyphae, pale red by 

 transmitted light, elliptic-oblong, 4-6 X 3 /x. 



Verticilli um 'lateritium, Berk., in Cke., Hdbk.,p. 635; Sacc., 

 Syll., iv. n. 808. 



On various decaying vegetable substances. 



[Verticillium Vizei, B. & Br., in Vize, Microfungi, n. 247. 



According to Saccardo, who has examined a specimen in 

 Yize's exs., this is the imperfectly developed mycelium of 

 Oospora perpusilla, Sacc. In the Kew copy there is only 

 mycelium, and that only in small quantity.] 



ACROSTALAGMUS. Corda. (figs. 6, 7, p. 358.) 



Vegetative hyphae creeping, septate ; fertile hyphae erect, 

 septate, primary branches in whorls that become smaller 

 upwards, secondary branches also whorled ; conidia aggre- 

 gated in clusters at the tips of the branchlets and involved 

 in mucus.
