NEW OR NOTEWORTHY FUNGI.— Part Y. 



By W. B. Grove, M.A. 



(Plates 542, 543.) 



This Notice of New or Noteworthy Fungi is a continuation of 

 Part iv, wdiich appeared in the Journal of Botany in January and 

 and February, 1912. I have to thank Dr. J. W. ElHs, of Liver- 

 pool, for kindly sending me several new species wdiich he has met 

 with, as also specimens of others which have not hitherto been 

 found in this country. The Birmingham Natural History Society 

 has kindly made a grant, from the Endowment of Research 

 Fund, towards defraying the cost of the plates illustrating this 

 paper. 



213. Sordaria coronifera sp. n. 



Peritheciis oblongo-conicis, plus minus immersis, |-1 mm. 

 altis, atris, rugulosis, ssepius ostiolo majuscule nitido conico in- 

 structis, tandem glabro apice umbilicatis, at sub apice pilis 5-15 

 atris acutis curvulis divergentibus, ex hyphis fasciculatis com- 

 positis, coronatis. Ascis clavatis, ca. 200 x 40 /x (part, sporifer.) ; 

 sporidiis ellipticis v. subamygdaloideis, albidis, dein fuscis, denique 

 opacis, atris, parte super, distichis, 32-40 x 18-23 /x, prime caudis 

 duabus hyalinis curvulis (inferiore longiore) pra}ditis, appendiculo 

 superiore tandem parvo hemisphserico, inferiore curvulo cylindrico, 

 ca. 15-20 X 4 /x. (Tab. 542, fig. 2.) 



Hah. in stercore equino, Earlswood, prope Birmingham, Oct. 



The appendages of the perithecia are as much as 350 /x long, 

 and point in all possible directions ; they are composed of many 

 fasciculated hyphae, but taper to an acute point. The texture of 

 the perithecium is soft, translucent-brown. This species is very 

 similar to the varieties coronata and aloides of S. curvula De By. 

 (Sacc. Syll. i, 234), but the appendages are more elaborate ; it is, 

 in fact, a further advance on them in complexity.

 D. imnctostoma Ellis in Amer. Nat. 1883, p. 316. 



Stroma elevated, tubercular, |-f mm. diam., formed from the 

 unchanged cortex, each enclosing 3-8 circinating perithecia, which 

 are monostichous and just pierce the dark-olivaceous disc by the 

 round ostiole. Asci clavate-cylindrical, obtuse and bifoveolate at 

 the apex, 55-60 x 8-9 /x (part, sporif.). Spores biseriate, except 

 above and below, oblong-elHpsoid, often somewhat attenuated 

 at one end, hyaline, 1-septate, 3-4-guttulate, faintly constricted, 

 12-14 X 4-41 /x. (Tab. 542, fig. 3.) 



On twigs of Apple, originally prepared for grafting, Bristol, 

 October, 1915 (comm. A. D. Cotton). The stromata occurred 

 mainly at the base of the twigs and w^ere accompanied on the 

 other parts by a large quantity of the pycnidial stage, Cijtospora 

 stictostoma Grove (see no. 227) and also by a curious minute 

 staurosporous Hyphomycete W'hose position could not be traced.
