Latin description. — Conidiis maxime gradatim in apicem acutis, dis- 

 tincte vel saepe insignite pedicellatis, typice magnopere arcuatis, 5-sep- 

 tatis, 49.2x4 (42-54 x 3.6-4.2) n, etiam saepe 3-7-septatis; continuis in 

 aeriis conidiophoris vel minutis mediocribusve (usque ad | mm. diam.) 

 sporodochiis in pseudopionnotes interdum vergentibus; chlamydosporis 

 intercalaribus sed non plurimis, continuis vel tantum minutis uveosis, 

 1-3-septatis; aerio mycelio fere plene mature-, uniformi, primum albo, dein, 

 in substratis parum glucosis, rubello varie tincto, substrato " pome- 

 granate" (R); in Solani tuberosi agare perglucoso, colore Tab. n, figg. 7, 8, 

 exhibito. 



Hab. In tuberibus putridis Solani tuberosi una cum F. anguioide, 

 Castile, New York, Amer. bor. 



Measurements of conidia on different media are as follows: 



On slightly acidified hard potato agar, culture twelve days old; conidia 



from aerial mycelium: 



Conidia: 0- and 1-septate, rare, immature 



3-septate, 17 per cent, 43x3.5 (35-56 x 3^.1)m 

 4-septate, 19 per cent, 49x3.5 (38-59 x 3-4.1 )/x 

 5-septate, 64 per cent, 54 x 3.7 (40-74 x 3-4.4)^ 



On red raspberry cane plug, culture seventy-five days old; conidia from 



aerial mycelium: 



Conidia: 3-septate, 10 per cent, 45 x 3.4 (28-51 x 3^)m 

 4-septate, 30 per cent, 50x3.5 (36-62.X 3-4.3) n 

 5-septate, 60 per cent, 53 x 3.6 (44-62 x 3.5-4) m 



On hard lima-bean agar with 2 per cent glucose, culture seven days old ; 



conidia from aerial mycelium: 



Conidia: 3-septate, 30 per cental (granulation of the protoplasm was too 

 4-septate, 15 per cent J great to clearly distinguish septation) 

 5-septate, 55 per cent, 53x3.8 (45-62 x 3.4-4.4) /* 



On hard lima-bean agar with 2 per cent glucose, culture twenty days 



old; conidia from pseudopionnotes: 



Conidia: 0-septate, rare 

 1-septate, rare 



4-septate, 4 per cent, 47 x 4.2ju (only two measured) 

 5-septate, 95 per cent, 54 x 4 (47-63 x 3.5-4.8) n 

 6-septate, 1 per cent, 52 x 4.1/* (only two measured)
