spores, and RcrkdeUa stromaticola (P. Henn) v. Hohnel. which 

 has tliree-septate spores, or are \vc to retain Berkdella for these 

 last-named species, and institute a neA\ genus for Hypomyces 

 stilbiger ? It w ould appear that, in spite of the prior sub- 

 generic application, Saccardo's order of pubhcation leaves no 

 option, and that we must accept Bcrkelella as at present 

 defined, with the t3^e species Berk, caledonica, thus excluding 

 Berkeldla siUhiqera. For the latter species I would propose a 

 new genus Byssostilbe — perithecia Hypomycetis : sporidia 

 fiUfonnia, multiseptata, in articulos globosos dilabentia ; 

 conidiojihora^ Stilbiformes. Ckilostilbe Penz. and Sacc. 

 (Malpigia. XL, p. 508) differs in having the asci polysporous 

 initially. 



In " Icones Fungorum Javanicorum ," tab. XXXIII.. fig. 

 4, p. 48, Penzig and Saccardo described OpMonectria (Ophios- 

 tilbe) TrichicB, which was discovered in Java, parasitic on 

 Trichia iierrncosa Berk. Their specimens were evidently 

 immature, and in all probability had been preserved in alcohol 

 as so many of that collection were ; when allowance is made 

 for those points, it is. I think, clear that their species is identical 

 with Hypomyces stilbiger B. & Br. They describe the peri- 

 thecia as parasitic, superficial, globosoconoid. wliitish, rather 

 villous. 130-140 [L diameter, with a rather long papillate 

 ostiolum : asci cylindric, shortly stalked, apex rounded, 

 70-80 X 4rA-6 [I, eight-spored ; no paraphyses ; spores fili- 

 form, pluriscptate, 60-Go x 7-1 [k hyaline. The coni- 

 (liophore is said to resemble i^tilbu7n tomentosum Schrad. : its 

 stalk is cylindric,*' exquisite papilloso-asperulo." 270-300 x 

 30-35 [J., whitish ; head subglobose, 60-65 [i diameter, 

 conidia not seen. They state that this species |)robably 

 const itulos a n(^w genus, which stands in the same relation to 

 Ophiomctria as Spha>rostilbe to Nectria, antl they suggest the 

 name Oplnodilbe for it. They did not, however, make use of 

 the latUfr name except as a subgeneric distinction. Unfortu- 

 nately, the spores are not filiform when mature, and therefore 

 it is impossililo to Jiccept Penzig and Saccardo's suggestion ; 

 for the prefix Ophio is usually reserved for the names of genera 

 in which the spores are liliform. It may, however, be admitted 

 that verv little is known about the ultimate condition of the
