1890.] FAIRMAN FUNGI OF WESTERN NEW YORK. 45 



species, Diplodia, 8, Sphccropsis 5, Phyllosticta 4. Pestalozzia is repre- 

 sented by one species, the rare Pestalozzia insidens of Zabriskie, found 

 on elms, which from the beauty and perfection of its spores has been 

 called the " Prince of Pestalozzias " (Plate 4, fig. 9). We find a Septoria 

 on common chickweed — Septoria Stellarice, R. and D., and Phyllosticta 

 Cirsii, Desm., on Canada thistle, new to the United States, until 

 discovered at Lyndonville. Haplosporella Nerii which grows on 

 oleander stems, Phoma capyrena on bittersweet branches, and Phyllos tic la 

 filipendulina on cultivated spiraea are forms which are new to New York 

 State. 



The Hyphomycetes are represented in the collection by a number 

 of species (also distributed among many genera) including Cercospora, 

 Pusicladium, Ovularia and Ramularia, parasitic on living plants, and 

 Botrytis and Verticillium on dead or decaying substances. While not 

 exerting as destructive action upon vegetation as some other fungi, this 

 group affords many delicate microscopic forms. Two members of this 

 group, viz: Pusicladium dendriticum or apple-peel fungus, and Ramularia 

 Pragarice or the strawberry leaf blight, have been found with us, 

 seriously injuring their respective hosts. 



The Hymenomycetes comprize nearly one-fourth the collection, and 

 our flora will be found quite rich in these forms. In the Agaricus 

 family we find many genera present with us, headed by Agaricus proper 

 with 22 species, and including members of such genera as Pussula, 

 Lactarius, Marasmius, Coprinus, etc. The striking feature is that no 

 specimens of the large genus Cortinarius, have, as yet, been found, 

 although looked for with assiduity. Elsewhere in the eastern portion of 

 New York State Cortinarii have been plentifully gathered. The family 

 Polyporei is represented by a number of genera and species. A few Boleti 

 have been found, in the months of July and August, in our locality, but 

 Polyporus has the larger number of species to its credit (about 20). 



It may be noted in passing that it has long been known to students 

 of fungi, that Polyporus applanatus often attains a large size and that its 

 pores are ferruginous, with a white orifice, which causes the inferior 

 surface of the plant to appear as if white-washed. It has also been 

 known that these whitened surfaces when bruised or scratched show 

 quickly the brown underlying color. I have seen this property made 

 use of in a decorative sort of way, which I have nowhere seen 

 mentioned. Pictures of trees, houses and various objects are drawn 

 upon the white inferior surface of the fungus and are permanent. In 

 many country houses these prepared objects are found plentifully 

 adorning mantels and bric-a-brac receptacles.
