The specimens appear to be Dothichloe, and resemble D. atra- 

 mcntosa.

The stroma is about 3 inches long, parasitic on bamboo. It is 

 apparently Balansia. 



Hypocrella semen Bres., in Henning.s. Fungi Brasilienses, 

 II., p. 524. ; Hypocrella Glaziovii P. Henu., Fungi Brasilienses, 

 II., p. 524. 



These two species Were described from Glaziou 18,069. The 

 type of Hypocrella semen is in Herb. Berlin ; the packet contains 

 a MSS. description by Hennings, under the name of Hypocrea 

 foliicola, and is marked by Hennings " et Helotiella Glaziovii.''' 

 The type of Hypocrella Olaziovii, also in Herb. Berlin, is part of the 

 same collection. 



Bresadola states that the asci of Hypocrella semen are 220-270 

 X 8-9 [J,, with filiform jnultiseptate spores. Hennings gives the 

 asci of Hypocrea Joliicola as 180-230 x 7-8 ^., with bicellular 

 spores, soon dividing into subglobose loculi, 5-6 [>, diam., and 

 those of Hypocrella Glaziovii as 40-50 x 10-15 [jl, with pluri- 

 He'ptsite filiform spores, 35-45 x 3-4 [x whicli divide into part 

 spores 5-8 x 3-4 [l. 



The fungus is circular, about 1 mm. diameter, flattened pul- 

 vinate, black-brown, on a slight brownish- white Weft of mycelium. 

 In section it is brownish-white at the base, above Mhich is a dark 

 brown convex stroma, sunrounted by a paler brown peripheral 

 zone. The lower layers consist of interwoven thin-walled hyphse, 

 which become parallel in the dark brown zone, aiid bear an upper 

 layer of asci and paraphyses about 0-2 mm. thick. The basal 

 layer ascends slightly up the sides. The asci are 6-8 [x diameter, 

 4-spored, with a rounded, not thickened apex. The spores are 

 120-160 X 3-4 [jL, septate, with divisions 3-5 ^ long, but do not 

 show anj^ signs of separation. The paraphyses are filifonn, and 

 fused above into an epithecium. This is evidently a Discomycete. 



Hypocrella marginalis P. Henn., Engl. Bot. Jahrb. (1903), 

 p. 49. 



Tlie type in Herb. Berlin, from East Africa, is a discomycete, 

 co-generic with the foregoing ; the spores, as far as observed, are 

 1*5 [t. diameter, with septa about 2 (j, apart, but they appear to 

 be immature. With the type is included a speehnen from Rio 

 Jurua (det. Hennings) which is identical with " Hypocrella 

 sefnen.'"
