NEW LABOULBENIALES FROM CHILE ANTD NEW ZEALAND.

During a stay of several months in Chile, which extended from 

 November, 1905 to March, 1906, the writer paid but scant attention 

 to the collection of Laboulbeniales; since, in the absence of any very 

 considerable number of insect hosts, his time and attention was largely 

 occupied with the very rich cryptogamic flora of this region, large 

 collections of which were made. The comparative rarity of hosts, 

 especially in the heavily forested area about Corral, was surprising; 

 and, with few exceptions, the parasites which occurred on them were 

 not characterized by any unusual peculiarities. Less than fifty spe- 

 cies were obtained, many of which were familiar. Among the latter 

 may be mentioned Herpomyces Ectohiae, Laboulbenia diversipes, L. 

 granulosa, L. sigmoidea, L. pedicillata, L. polyphaga, L. Pterosticki, 

 L. Tachyis, L. variabilis, L. vulgaris, Corethromyces Stilici, Acomp- 

 somyccs brunneolus, Ecteinomyces Trichopterophilus, Ceratomyces 

 viirabilis, C. filiformis, and Coreomyces Corisae. A small number of 

 forms were also found which, although new, were not in sufficiently 

 good condition for description. These include two species each of 

 Rhachomyces, Mimcomyces and Corethromyces, as well as several 

 species of Laboulbenia, a genus now in some confusion. Stigmatomyces 

 Chilensis, described in These Proceedings, 52, p. 685, should also be 

 added to the list of forms obtained. 



The flora of southern Chile and New Zealand being similar in many 

 respects, I have ventured to include in the present enumeration five 

 species which were found in a small lot of beetles very kindly collected 

 for me by Messrs. Eames and Sinnott at Aukland, in 1910. I am 

 further indebted to Mr. Gilbert J. Arrow of the British Museum for 

 several determinations.
