Catinula turgida (Fr.) Desm. 

 On dead branches of Corylus cornuta Marsh. ( C . 

 rostrata Ait.) Newcomb, Essex county. H. D. House, June 

 21, 1923. Also collected at Albany by Doctor Peck, on Corylus 

 americana Walt., and at West Fort Ann, by Burnham, on

Myxosporium Liriodendri Dearness & House, sp. nov. 



Acervuli immersed, thickly and regularly scattered as dark specks 

 on the white, soft shoots of the host, .4-.5 x .275 mm. opening by 

 roundish or slitlike perforations of the cuticle. Conidia hyaline, 

 navicular, binucleate, 6-10x2^-3 /x, mostly 8x2^ /x, on basidia 

 10-15 X 2 /X. 



On dead shoots of the first year's growth of Liriodendron 

 Tulipifera L. Oneida, Madison county. H. D. House, June 

 24, 1922. This appears to be quite different in every respect from 

 Myxosporium coloratum (Peek) Sacc.,*^ on dead 

 limbs of the same host. Myxosporium longisporum 

 Edgerton,*^ described on twigs of the same host species from Pough- 

 keepsie, N. Y.. has conidia 30-48 x 12-15 fx. 



Cylindrosporium fraxinicolum Dearness & House, sp. nov. 



Spots subcircular, not bounded by the veinlets, 3-8 mm in 

 diameter, immarginate but surrounded by a pale border, 2-4 mm 

 wide, dull reddish-yellow above, paler beneath. Small, dark, Pig- 

 gotialike pycnidia hypophyllous on a few of the spots. Acervuli 

 epiphyllous, depressed pulvinate. strictly nervisequent, circular. 80- 

 100 /x, but often linear or interruptedly linear from J4 to 2 mm along 

 a nerve, colorless or concolorous. Conidia hyaline, linear, nearly 

 straight, nucleate, continuous or obscurely one to three septate, 



18-30x2 IX. 



On living leaves of F r a x i n u s americana L. Bolton, 

 Warren county. H. D. House, July 20, 1917. This has been care- 

 fully compared with authentic material of four other species of 

 Cylindrosporium occurring upon Fraxinus. and difiPers from all of 

 them by the circular banded spots, nervisequent acervuli and 

 narrowness of the sporules.
