MPLOCLADIUM. 335 



imperfect wlioii of 3-4 short, erect brancblets ; com'dia 

 apical, solitary, elliptic-clavate, becoming 1-septate, 12-14 

 X 5fi.. 



Diplocladium penicillioides, Saoc, Syll., n. 872 ; Grev., pi. 

 150, fig. b. 



On decaying species of Polyporus, Agaricus, and Partus ; 

 along Hypomyces aurantius, of wbicb it is considered to be tbe 

 conidial form. 



Diplocladium melleum. Sacc (fig. 24, p. 313.) 



Forming minute, honey-coloured tufts ; hj-phae branched 

 at the apex, branchlets arjanged in whorls^ acute at the tip ; 

 conidia elliptical, base slightly attenuated, almost colourless, 

 12-14 X 5-6 fjL. 



Diplocladium melleum, Sacc, Syll., n. 874. 



Dactylimn melleum, B. & Br., Ann. Nat. Hist., n. 1382 

 t. 8, f. 6. 



On old specimens of Polyporus and Stereum. 



Diplocladium tenellum. Mass. 



Tnfts white or with a reddish tinge ; hyphae aggregated, 

 fertile, short, slender, erect, septate, branchlets short, sub- 

 verticillate ; conidia slightly obovate, colourless, 1-septate, 

 in clusters of 3-4 at the ti]ps of the branches, 12-13 x 6 /t. 



Mucrosporium tenellum, Sacc, Syll., n. 924. 



Dactylium tenellum. Fries, Syst. Myc, iii. p. 413. 



An examination of authentic specimens shows the spores 

 to be constantly 1-septate, hence the species cannot be a 

 Mucrosporium, as placed by Saccardo. 



Diplocladium macrosporum. Mass. 



Sterile hyphae loosely interwoven, white then pale rose- 

 colour ; fertile subverticillately branched at the apex ; 

 conidia elliptic-oblong, apioulate at the base, colourless, 

 1-septate, 20-25 x 8-10 u, produced in cluster-s of 2-3 at the 

 lips of the branchlets. 



Dactylium macrosporum, Fries, Syst. Myc, iii. p. 414; Sacc 

 Syll., iv. n. 918. 



On bark, moss, &c. 



The spores are constantly 1-septate, hence the present 

 Rpecies cannot belong to the genus Dactylium, where it was 

 placed by Saccardo.
