302 Dopcre: LACHNEA WITH A BOTRYOSE CONIDIAL STAGE 
The conidia of Lachnea abundans are smooth at maturity 
while those of Sclerotinia Geranii are rough or warted, otherwise 
their conidial stages are very similar. The connection between 
the apothecial and the conidial stage of L. abundans has been 
established repeatedly by cultures from single conidia and from 
single ascospores, apothecia arising in each case within a week 
or two after showing the spores. 
Fic. 1. Part of a dichotomously branched conidiophore showing the en- 
larged ends of the ultimate branchlets upon which spores will be borne. 
Fic. 2. End branches of a similar stage more highly magnified, spore 
buds arising from two of the globular heads. 
Fic. ortion of an old: conidiophore showing botryose clusters of 
spores, A, developed on about sixteen fertile ends; B, shows the collapsed 
ends of the conidiophore after the spores have been dislodged. 
Fics. 4 and 5. Germinated ascospore becomes a cell in the hypha; F1G. 5 
also shows ungerminated ascospores. 
Ascospores germinate very readily when the inoculated culture
