including both the conidial and the sclerotial stages, which he assumed 

 belonged to the same species. His description is as follows: 



Botrytis parasitica nov. sp. Hyphis cinereis sparsis, erectis, articulo basali inflato; gonidiis 

 ovatis, magnis, breviter pedicellatis, in ramulis minutis, capitatis, umbellatim dispositis; 

 hyalinis vel dilute cinereis, 16-20 x 10-13 M. 



Forma scleroziale. 



Sclerotium Tulipae Lib. Haemisphaericum, vel oblongum, nigrum, vix rugosum, super- 

 ficiale vel immersum, intus albidum §— 1 mm. latum. 



Hab. Ad folia, caules, petala, et capsulas Tulipae Gesnerianae in Horto botanico ticinensi. 



Cavara (1888:432) justifies his description of this species as a new one 

 on the basis of morphological differences and also because of its strong 

 parasitic action. In his discussion of nomenclature, he says that Sclerotium 

 Tulipae Terry, which infects tulips in the south of France, according to 

 Saccardo (1888-89,) is probably a synonym of Sclerotium cepivorum var. 

 Tulipae Desm., and perhaps is the same as Scl. cepae Desm. Cavara was 

 not able to compare specimens of Scl. Tulipae Terry with Scl. Tulipae Lib. 

 The writer, however, had an opportunity to examine a specimen of the 

 former at the herbarium of the New York Botanical Garden. This specimen 

 consists of three or four sclerotia with no adhering plant material. The 

 sclerotia are large, however, and are not those of Botrytis Tulipae (Lib.) 

 comb. nov. At the same place the author was able to see some of the 

 collection of Cavara designated Botrytis parasitica Cav., and found it to 

 be identical with his own collections. 



Massee (1899:383) describes the organism as Sclerotinia parasitica. 

 This description was not based on a perfect stage and in Massee's key 

 is placed under " Conodial form only known." Since there is no evidence 

 that the species under consideration is a Sclerotinia, this name is not 

 valid. Massee's description is as follows: 



Sclerotinia parasitica, Massee; Botrytis parasitica, Cavara. Conidiophores grey, scattered, 

 erect, basal joint inflated; conidia obovate, large, shortly pedicellate, on short umbellately 

 arranged branchlets, hyaline or tinged grey, 16-21 x 10-13 M; sclerotia formed in the paren- 

 chyma of the host, globose-depressed, smooth, greyish, then black, 2-3 mm. diam., sometimes 

 numerous, and forming black crusts. 



Botrytis on leaves, stem, and flowers of cultivated tulips; sclerotia more especially on 

 the bulbs. 



Distr. Holland, Britain. 



A consideration of these facts has led to the following designation of 

 the species:
