DIpIocladium pcnicilUoideSy Sacc, Syll., n. 872 ; Grev., pi. 

 150, lig. b. 



On decaying species of Polifjwruff, Agaricus, and Panus ; 

 along Hyjiomyces aurantiiis, of which it is considered to be the 

 conidial form. 



DIpIocladium melleum. Sacc. (fig. 24, p. 3i;3.) 



Forming minute, honey-culonred tufts ; hypliao branched 

 at tlie ajK'x, branchlets ananged in whorls, acute at the tip ; 

 <()nidia elliptical, base slightly attenuuted, almost colourless, 

 12-14 X o-G fx.

On old specimens of Pohjporus and Stcrcum. 



DIpIocladium tenellum. Mass. 



Tufts white or with a reddish tinge ; hj-phae aggregated, 

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

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

 in clusters of 3-4 at the tips of the branches, 12-13 X 6 /a. 



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



Pactylium 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. 



DIpIocladium m.acrosporum. Mass. 



Sterile hyphae loosely interwoven, white then pale rose- 

 colour ; fertile subverticillately branched at the apex ; 

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

 1-septate, 20-25 x 8-10 a, produced in clusters of 2-3 at the 

 tips of the branchlets. 



Badylium 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 

 species cannot belong to the genus Dactylium, where it was 

 placed by Saccardo.
