“Onygena pilifera Fr. This curious species occurred on the ejected 
pellet of an owl on Ashwicken Fen, 25th June, 1897. Mr. T. Petch. 
317. Aylaria longipes Nitschke. Stroma erect or variously curved, 
growing on the thicker, fallen, decaying, decorticated branches, general- 
ly single, sometimes 2-3 joined at the base. Ascophore generally simple, 
terete, cylindrical, thick, apex very obtuse, rounded more rarely 
ventricose inflated, oblong, very rarely compressed, entire or bipartite, 
superficially reticulato-rimose, at first clay-coloured then black, ostiola 
small, hemispherical, prominent, nigropunctate. Stem variable in 
length, but always much thinner than the ascophore and attenuated, 
thickened and tuberose at the base, with thick, distinct or interwoven 
and adpressed, reddish black hairs, smooth above, plicato-rugulose, at 
first clay-coloured then brown. Conidiiferous hymenium greyish 
white, soon disappearing, conidia obovate, small 8x 4-5 w on very 
short sterigmata, acrogenous. Perithecia immersed, not prominent, 
small, globose or compressed, crowded but uniseriate. Asci cylindrical, 
stipitate octosporous 80-100 x 7-8 w (sporiferous portion). Sporidia 
obliquely uniseriate, ovate, unequilateral, black 11-14 x 5-6 |.

King’s Lynn, September, 1896. 
This species occurred in considerable abundance and is evidentl 
an autumnal one. It is distinct from all forms of LY. polymorpha by 
reason of its much smaller perithecia. From ¥. corniformis the larger 
size of the sporidia and asci as well as the development of the stem 
and other characters separate it. “The sporidia are binucleate.

318. Xylaria Tulasnei Nitschke. Apex of the club acute. Stroma 
growing from the ground or from rabbit’s dung, simple, black, slender, 
filiform, flexuose or contorted, base variously thickened, sclerotiform, 
often just below the club, but not at the base, covered by an abundance 
_ of dense hairs, variable in length, conidiiferous hymenium grey, conidia 
very minute obovato-globose. Ascophore globose or greatly thickened 
at the base, apex sterile, acute, attenuated to a point. Perithecia pro- 
minent mammillate rather large, asci_ cylindrical, shortly pedicellate, 
Octosporous, with very long, filiform, thin and septate pseudo
