30 ILLINOIS BIOLOGICAL MONOGRAPHS [196 



On unknown host. 



British Guiana: Demerara-Essiquibo R. R., July 15, 1922, 331. 



The material of this collection is scant but generic agreement seems 

 certain. The asci measure 126x43//, spores 32 to 36 x 14 to IS/j. The spores 

 when mature are dark. Though the spores measure somewhat less than 

 as given in the description this collection is provisionally referred to P. 

 melioloides. 



40. Parodiopsis viridescens (Rehm) Arn. 



Notes Myc, p. 23, 1915. 



On Banisteria ciliata. 



British Guiana: Coverden, July 8, 1922, 772. 



Two species of Parodiopsis are listed by Arnaud as on Malpighiaceae. 

 Our specimen agrees most nearly with the above named species, which 

 was made the type of a new genus, Hypoplegma, by Theissen and Sydow, 

 which however is rejected by Arnaud. The type of the species is on an 

 undetermined species of the Malpighiaceae collected in Brazil (Ule No. 

 1378) with spore measurements given by the author as 35 to 40 x 10 to 11/i, 

 by Theissen and Sydow as 45-55 x 10-1 2/i. The spores of our specimen 

 measure 32 to 36 x \\n. 



41. Parodiopsis ingarum (P. Henn.) Arn. 



Les Asterinees Ann. d. 1' ecole nat. d. Agr., Montpellier, 1918. 

 Parodiella viridescens Rehm. var. ingarum P. Henn. 



On Inga sp. 



British Guiana: Coverden, August 8, 1922, 78Z, 802. 



Our specimens agree well with the descriptions, especially so as to the 

 color of the perithecia and the shape and size of the spores. The species 

 of the Inga has not been determined but it is an unusual one with leaflets 

 long and narrow, usually about 80 x 13 mm. 



Arnaud mentions the presence of numerous setae resembling in their 

 tips geniculate conidiophores though no conidia were found. My speci- 

 men shows numerous, erect hyphae also resembling geniculate conidio- 

 phores. A Heliminthosporium parasitic on the Parodiopsis is also present 

 and is described elsewhere. 



Examination of the microtome sections shows tissue to considerable 

 depth under parts of the colonies to be heavily occupied and killed by 

 internal mycelium. 



42. Parodiopsis sp. ind. 

 On Apocynaceae (?). 



Trinidad: Guanapo, August 16, 1922, 976. 

 The specimens are clearly of Parodiopsis aspect and bear the perithecia 

 in concentric rows but no asci could be found. Large dead spots are pro- 

 duced in the leaf.
