394 THE DEUTEROMYCETES (FUNGI IMPERFECTl) 



torily solved. Sampson (1928) properly employed Kabatiella 

 caulivora for the red-clover pathogen previously designated 

 Gloeosporhnn caulivonim. Its conidiophores and conidia and 

 their germination and type of growth in culture are entirely like 

 those of the so-called Protocoro7Wspora nigricans on vetch. The 

 vetch pathogen, therefore, appears properly to belong in Kaba- 

 tiella. 



The conidial stages of the black-spot fungus on roses and the 

 leaf-scorch fungus on strawberries belong in the form Genus 

 Alarssonia. The closely related Marssonina panattojiiana, causing 

 "shot hole" on lettuce grown under glass, is not known, however, 

 to possess an ascigerous stage. 



The twigs of peach throughout Europe and North America 

 may be parasitized by Coryneinn beijerinckii. Acquaintance 

 with Pestalotia (Pestalozzia), characterized by septate conidia 

 that bear three or more hyaline setae, may be gained from the 

 monograph by Guba (1929, 1932). 



Three species of Higginsia (Coccomyces), a discomycetous 

 genus occurring on Prunus, namely, H. hiemalis^ H. pnmophorae, 

 and H. hitescenSj have hyaline, thread-like conidia that belong in 

 Cylindrosporium. The ascigerous stage of all other species of 

 Cylindrosporium remains unknown. 



MONILIALES 



The Moniliales comprise 651 genera and more than 10,000 

 species, according to Bender (1931), and are divided into 4 

 famiHes. In the Moniliaceae there are 204 genera, in the Demati- 

 aceae 206, in the Stilbaceae 89, and in the Tuberculariaceae 152. 



Moniliaceae. Certain members of this family, notably Asper- 

 gillus and Penicillium, are encountered by mycologists, bac- 

 teriologists, and plant pathologists everywhere for the reason 

 that they are ubiquitous in distribution and essentially omnivorous 

 in food habits. A few species of both genera are known to de- 

 velop a perfect stage of the plectomycetous type and were for- 

 merly placed in the Genus Eurotium. Most of them, however, 

 are detached conidial stages. The erect conidiophore in Asper- 

 gillus is apically enlarged, and from the surface of this enlarge- 

 ment short bottle-shaped branches (sterigmata) arise. From each 

 branch a chain of conidia is produced; instead the branch may
