62 ' 6 [JL long, besides which there are sometimes round curved 

 hairs ; sporidia 12 '5-15 [>. long, 6*25 [l wide." 



Under Nedria flavolanata in Herb. Kew are Thwaites 1103 

 (239 in part) marked by Thwaites, "apparently No. 1102 

 infected with a yellow mould," and another sheet marked " 239 

 Nedria fulvo-lanata B. & Br. Hypoxylon quisquiliarum Mont." 

 The Nedria in the latter case is N. flavolanata. In explanation 

 of these data it must be noted that Thwaites put together 

 several gatherings under the number 239, and subsequently 

 separated them. 2396, which was N. flavolanata, then became ' 

 1103, * while 239a, which was Hypoxylon quisguiliarum, 

 became 1072. The specimen in Herb. Peradeniya is marked 

 1103 (239 part) "apparently 1102 infected with a mould." 

 The Peradeniya specimen is the same as that at Kew. 



In the tjrpe specimen the perithecia are scattered, or 

 aggregated in clusters up to 2 mm. diameter. They are ovoid, 

 0*3 mm. diameter, 0*4 mm. high, ostiolum slightly papillate, 

 sometimes collapsing when dry, rather pale red, darker round 

 the ostiolum, covered with minute yellow flocci, densely 

 below, more sparsely above. In the Peradeniya specimen 

 the yellow, or greenish-yellow, mycelium sometimes spreads 

 over the surrounding bark. The hairs are yellow, flexuose, 

 usually short, up to 90 [i. long, 4-8 ^. diameter, septate, some- 

 times inflated at the tips, minutely spinulose, often encrusted, 

 often arising from the perithecium wall in tufts. There are 

 also shorter, stouter, more rigid, recurved hairs. The wall of 

 the perithecium is composed of thick-walled polygonal ceils 

 about 10 [i. broad, and appears areofated when mounted ; it 

 sometimes bears a few minute warts. Round the ostiolum the 

 cells are tangentiaUy elongated. When mounted, the wall 

 sometimes appears yellow, sometimes red-brown. The asci 

 are eight-spored, with spores usually biseriate, clavate, shortly 

 pedicellate, 50-70 X 8-10 [j,. A few strap-shaped paraphyses 

 are present, but they do not appear to be septate. The 

 spores are narrow-oval to oblong-oval, sometimes slightly 

 fusoid, one-septate, not constricted, wall striate, hyaline, 

 15-17 X 5-7 [i, exceptijanally 13 X 6 [jl, or 16 x 9 [jl. I do 

 not find the conidia described by Berkeley and Broome ; 

 obviously some of them are Fusarium spores.
