195] PARASITIC FUNGI— STEVENS 29 



states that the fungus is questionably capnodiaceous; it appears, however, 

 to me to be perisporiaceous, and I so place it. 

 Haraea Sacc and Syd. 

 Ann. Myc, 11:312, 1913. 



38. Haraea mauritiae Stevens n. sp. 



[Figures 71-76] 



Mycelium superficial, smooth, brown, 3.5/i thick, freely anastomosing, 

 bearing pseudohyphopodia either axillary to the branches or laterally. 

 Perithecia globose, densely setose, astomate, 123 to 154ju in diameter. Per- 

 ithecial setae 54 to 154;u long, otuse, tapering, 7ju thick at the base, 3fi at 

 apex. Asci 92 to 123ju, ovate, stipitate. Spores 50 to 61 x 10 to 1 1;^, hyaline 

 and 1-septate when young, constricted and readily separating, cyHndrical, 

 straight or slightly curved, ends rounded, usually slightly unequally di- 

 vided, 3-septate and brown when mature. 



On Mauritia sp. 



Trinidad: Guanapo, August 16, 1922, 908. 



The pseudohyphopodia are peculiar consisting of a stalk cell either 

 short (to sessile) or long (10-25ju) and a head usually about 27x14^ consist- 

 ing of a tangle of cells (Figure 76). The function of these is unknown. 

 Parodiopsis Maub. 



Bui. Soc. Myc. de France, 31:3, 1915. 



This genus was established on the species Parodiella melioloides Wint. 

 because this species possesses an abundant superficial mycelium which 

 properly is not found in Parodiella. The genus is regarded by Theissen 

 and Sydow'" (1917) as belonging to the Perisporiaceae. Arnaud" places 

 the genus in his tribe Parodiopsidees in his family Parodiellinacees and 

 unites with Parodiopsis the following genera: Chrysomyces Theiss and 

 Syd., Schistodes Theiss., Hypoplegma Theiss and Syd. Perisporiopsis P. 

 Henn. and Piline Theiss. Theissen and Sydow regard only one species of 

 the genus as tenable while Arnaud recognizes five species as well estab- 

 lished and six others tentatively so. Three of the tentative species of 

 Arnaud have been placed by the other mycologists in other genera viz 

 Chrysomyces, Perisporiopsis and Piline. In the following species deter- 

 minations the conceptions of Arnaud as to the specific characters and 

 limitations are followed. 



39. Parodiopsis melioloides (Wint.) Arn. 

 On Alchornea cordala. 



British Guiana: Tumatumari, July 10, 1922, 75i; July 8, 1922, (5J. 

 This specimen agrees perfectly with the original description but the 

 perithecia are not found in concentric rows as is so common on many other 

 hosts.
