Sclerotinia Candolleana Sclerotium pustula de Cand. 



— echinophila 



— ficariae 



— tuberosa 



— sclerotiorum — varium etc., (Sphacelia see Appel &. 



BruckO?^'^). 



— Fuckeliana — echinatum Fuck. 



— trifoliorum 



— subularis. 



I must consider it quite inadmissible to use the name of Sphacelia 

 which has been applied to a conidial form of a Pyronomycet, also 

 for a conidial form of a Discomycet even if they are morphologically 

 alike. 



Although it has already been stated quite correctly by de Bary 

 (66^°^) that Sclerotinia sclerotiorum only produces ascomata and no 

 Botrytis, several subsequent mycologists (for instance Schroeter 08^^, 

 Frank 96"'°) maintain that Botrytis cinerea forms the conidial stage 

 of Sclerotinia sclerotiorum as well as of Sclerot. Fuckeliana. In later 

 years it has, however, been agreed that Sclerotinia sclerotiorum does 

 not correspond to any form of Botrytis (see for instance R 02 a^"^). 

 But in most systematic papers there prevails a great confusion as to 

 Sclerotinia Fuckeliana of which most mycologists say that it is fur- 

 nished with ascomata and Botrytis as well. Therefore I must point 

 out — although this is no new thing — that Sclerotinia Fuckeliana 

 (= Sclerotium echinatum) is a true Sclerotinia, which rather seldom is 

 to be found on leaves of Vitis vinifera. Botrytis cinerea (= Sclerotium 

 durum) is a common Hyphomycet which has no relation whatever 

 to any known Sclerotinia nor is any species of Sclerotinia related to 

 any Botrytis. The mistake originates in the fact that Sclerotium durum 

 and Sclerotium echinatum are often found in the same substrate and 

 that the mycelium of Botrytis is like that of Sclerotinia sclerotiorum 

 (see Syll. VIII, Brefeld Heft. X^'\ Ralph Smith in Botanical Gazette 

 vol. 29 1900).
