NEW OR NOTEWORTHY FUNGI 47 



intermixed in the same pycnidimn, and so there can be little doubt 

 that Phyllosticta carpathica All. & Syd. in Hedwig. xxxvi. p. (157) 

 is merely the younger condition of this fungus.

 Sacc. Syll. xi. 523. Allesch. vi. 637. 



Spots epiphyllous, fuscous, unbordered, at first small, at length 

 Sj)reading over the leaf. Pycnidia epijihyllous, punctiform, 60-75 ^ 

 diam., very pale brown, translucent. Spores subcylindrical, straiglit 

 or rarely bent, hardly constricted, colourless, with 2 or 4 guttules, 

 10-12 X 3-4 yu, : sporophores very short.

 Syll. xi. 525. Allesch. vi. 661. Died. Pilz. Brand, p. 393. 



Spots scattered, circular or nearly so, very minute, scarcely \ mm. 

 diam., pale-oehraceous, thickened at the edge, surrounded by a much 

 broader purple-brown border. Pycnidia epiphyllous, few, rather 

 crowded (but sometimes only one on each spot), about 100 /x diam., 

 subglobose, black, piercing the epidermis and at length becoming 

 somewhat superficial ; texture thin, pale-brownish. Spores oblong- 

 cylindrical, obtuse at both ends, often bent or Hexuose, with a septum 

 which is sometimes median, sometimes above the middle, slightly 

 constricted, 15-20 (or even 30) x 4-6 ^, cloudy and furnished with 

 2, 4, or more guttules. (Fig. 6.) 



On dead pinnules and petiolules of Uteris aqiiilina, lying in damp 

 places. West Kilbride, A3'rshire (Boyd). July. 



According to German accounts, the fungus appears first on the 

 living leaves ; when it occupies the j)etiolules, the 23art of the leaf 

 above that place dies and becomes brown, by which means the 

 presence of the fungus can be recognised at some distance. 



337. AscocHYTA Stellarle Fautr. in Kev. Mycol. 1896, p. 68. 

 Sacc. Syll. xiv. 943. Allesch. vi. 665. 



Spots none or indefinite. Pycnidia more or less aggregated in 

 patches on the dead leaf, immersed, hardly prominent, 150-200 fj. 

 diam., globose-lens-shaped, honey-fuscous, pierced by a pore ; texture 

 very thin, membranaceous, pale, excejDt for a narrow dark circle round 

 the faintly projecting pore. Spores irregular, oblong, rounded at both 

 ends, colourless, very clouded and multiguttulate within, eseptate, 

 slightly curved at times and bent as if about to become 1 -septate, 

 but not constricted, 23-30 X 6-7 /x. (Fig. 2.) 



On fading or dead leaves of Stellaria uliginosa. West Kilbride, 

 Ayrshire (Boyd). May. 



The spores of these specimens, being irregular in form, sometimes 

 clavate or even pyriform, have a very unusual look for an Ascochyta, 

 ,and have more the appearance of going to be a Sfayonospora. J3ut 

 there was no septum visible, although there were the usual signs that 

 one or more were going to be formed. The texture of the pycnidium, 

 however, was truly Ascochyta-\\kQ\ the narrow black line around 

 the pore is conspicuous even with a lens.
