16 THE JOl'KNAL OF IJOTAXY 



On (le;i(l leaves, sepals, and petals of llclianthrmHm. Tereeton, 

 Ayrshire (Boyd). Aug. 



Most of th^ pycnidia contained only the spores described above, 

 but here and there, in the same j^yoiidia, were also found many 

 Sepforia spores, cylindric-hliform, egiittulate, 25-(50 X 1-2 ^ ; these 

 could hardly be anything else than Sepforla IIe/i(fnfJiemi {\est.) 

 AUeseh. The pycnidia were exactly as in Yestergren's description, 

 ex(!ept that none were found quite so large,

Spots brown, irregular-roundish, without a definite border. Pyc- 

 nidia as in the type ; spores ellipsoid, somewhat curved, apiculate at 

 base, 7-9 X 2-2^ ^<.

 shire (Boyd). Aug. 



The variety differs from the type (which was found in France) in 

 the size and colour of the spots (brown instead of grey) and in the 

 lono-er, narrower, and curved spores (spores of the type oval, 

 5-7x3ju).

Spots none. Pycnidia scattered, few, chiefly epiphyllous, globose- 

 lens-shaped, minute (about 125 /x), black; texture thin, pale-brown, 

 slightlv darker near the roundish pore. Spores numerous, oblong or 

 cylindrical, rounded at both ends, hyaline, biguttulate, 5-0 xl\ p.

 shire (Boyd). July. 



The spores were much more regular than those described by 

 AUescher, and were never more than 1| ^ wnde ; his specimens \vere on 

 iS. Holostea.

Spots indisthict, brownish. Pycnidia lens-shaped, punctiforni, 

 black, about 70-80 /i diam., pierced by a pore ; texture distinctly 

 parenchvmatous, clear brown, darker round the ])ore. Spores oblong- 

 cylindrical, straight or faintly curved, biguttulate, 4-5 x 1-1^ /<.

 winning, Ayrshire (Boyd). Sept. 



The pycnidia are chiefly situated on the upper side of the rays. 

 The spores are exactly those of Fhyllosticta, but the pycnidial tex- 

 ture approaches that of Fhoma.

vi. 134. 



Spots various, chiefly marginal, wlutish-pallid, with a golden- 

 tawnv border. Pycnidia few, epiphyllous, scattered, lens-shaped, 

 brown, pierced by a pore ; texture very thin and translucent. Spores 

 oval or ovoid, tapering slightly below, about 5 X 2^ ^/.
