Fischer succeeded in obtaining stalked ascocarps from -ck-rotia 

 <>f one and two years old. They resembled mo>t do-dy those 

 of .xV 7. vacdnii, their stalk being provided with numerous ihix- 

 oids. The asd contain eight similar spore-, which -ermiiMte 

 directly on ejaculation. They develop a niyeeliuni and, lal 

 chains of chlamydospores which separate by means of disjunct. .1-. 

 The little conidia found by \\'or.>nin on I '///////////// are never 

 produced. The paraphyses are generally unbranched and con-e- 

 sjiniid in length to the asci. 



The mummified fruits are easiest found after the healthy 

 capsules have dehisced, then the diseased ones remain elo> t -d. 

 In winter the healthy capsules remain attached to the plant 

 the di-ea-ed fall off. Seeds of diseased capsules are completdv 

 overgrown by hypha.-. 



Wahrlich 1 found sclerotia in capsules of lUt<l. dnlmrii ///// 

 from Silieria. They u'ave off a selerotial ascocarp with a -talk 

 devoid of rhi/oids. The mummitied fruits resemble closely tho-e 

 of Scl. /'/nil/in// //!///. 



Scl. heteroica Wor. et Xaw. = Scl. ledi Xaw.' J occurs on 

 I.'iluni fining,;- in K'ussia and Finland. It is very similar to 

 ,sW. rlimlnil, in/i-i. Imt is distinguished ly the paraphyses l>eini: 

 -wolleii and freipiently forked at the end. In nutritive -datine 

 a copious mycelium is developed, and produce- chain> of ripe 

 conidia with tiny disjunctors. Woronin found that these conidia 

 are produced only on Vaccinium uln/i/mxnm, never on /,"/*'///: 

 hut the conidia 80 ioimed can siicco-tully infect the ovary of 

 L'llnin. \\'.- have here the first known case of lieteroeci-m 

 on i side i lie I r.-dineae. 



Scl. sclerotiorum Uh. ; (I'.ritain and I'.S. America). The 

 sclerotia of this fun-us ai.- found in many various plants. 

 They fail to the -round with the dead plants, hibernate under 

 -now, and on the arrival of warmer weather in spiinu -ive 

 n-c to M-vefal .-talked a]iothecia. The aSCOSpOreS are ejacidat.-d 

 from the asci, 'jcrminale. and produce a par.i-itic mycelium.
