 247, I luentioiied i\ fungus found in J1M)1 hy Mr. C. A. (1. 1)KINS 

 at Nnnspeet on tiie needles of Piniis silxeslris, wliicli fungus, dis- 

 covered in J 840 on the same host near Prague by the botanist 

 A. J. C. CoHDA, was described in vol. IV of his "Icones Fungornni" 

 on page 40, nnder the name of Sphaeronemtr pythlopldlimi ') 



The same fnngns received a |)lace in Saccardo's "S^'lloge b'uu- 

 gorum", vol. Ill (A" 1884), p. 101, this time nnder the name of 

 Phoma jnti/op/u'Ia, whereas on account of a new investigation of 

 fresh specimens I Ihouglit it necessary myself, in the article (pioled 

 above, to change the name Phoma again and to rej^lace it by that 

 of Sclerotiopsis. 



Besides Saccardo, also Allescher, in the 6''' vol. of Winter's 

 Kryptogamen-Flora (1901), page 199, w^q':^ \\\q wamQ Phoma pity o phila 

 for this fnngns, which name is changed into Sclerotiopsis, by way 

 of improvement, in vol. VII, p. 847 of the same work. 



Having been enabled through the kindness of Mr. Beins in January 

 1904, to examine again some fresh specimens of Sclerotiopsis 

 pityopldh, I availed myself of this opjiortunity of testing once more 

 my former exjierience by facts and had the advantage of having at 

 my disposal the drawings l)y Mr. V. J. Koning, chemist ai Bnssum, 

 which accompany this article. I have to thank Mr. Koning for the 

 kindness which he has repeatedly shown m assisting me on former 

 occasions as well as on this. Some particulars snj)plenienting' former 

 communications ma}' be mentioned here. 



The reason that induced Saccardo in 1884 to change the name 

 Sphaeronema into Phoma was that some very characteristic |)roperties 

 of the former genus had been passed over silently by (!orda, viz. 

 that in his paj>er no mention is made either of a beak- oi- brush- 

 sha[)ed prolongation of the peritheciunnvail or of spores which, 

 conglomerated to a l)all, should have been found at the surface of 

 the perithecia. 



The generic name chosen by (!orda could not bo regained aiul so 

 no other name seemed more a|)propriate to the Italian mycologist 

 to rej)lace it than that of Phoma, which jndgnieut has not been 

 doubted by any subsecpient writer.

 has been corrected.
