In pseudopionnotal stage F. anguioides is much like F. biforme, but 

 has no sporodochial stage, or rather no macroscopically observable spo- 

 rodochia. 



Latin description. — Conidiis variis typis, interdum arthrosporialibus 

 (brevibus, fusiformibus, terminis plus minusve rotundatis, 0-3-septatis) , 

 interdum typice paulum curvatis vel prope rectis anguiformibusque, 

 1-15-septatis; conidiis primo typo typice 1-vel 3-septatis, 27 x 4.4 

 (20-38 x 3. 9-5.3 )/*; conidiis altera typo: 5-septatis plerumque 51x4.2 

 (47-68x3.9-4.6)/*; 6-7-septatis plerumque 76x4.6 (65-86x4.2-5.2)/*; 

 8-9-septatis plerumque 89x4.86 (80-102 x 4.3-5.8) /*. Conidiis in strato 

 pseudopionnotali, in agari glucoso Solani tuberosi e pallide "pinkish- 

 cinnamon" (R) "cinnamon" (R); saepe conidiis arthrosporialibus in 

 aerio mycelio, sed hoc mycelio saepe — imprimis in alio agari — prope 

 absente, quae cum ita sint tenues sporarum strati, pseudopionnotes, 

 oriuntur cum conidiis typice anguiformibus. 



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

 Castile, New York, Amer. bor. 



Measurements of conidia on different media are as follows: 



On red raspberry cane plug, culture sixty-two days old; conidia from 

 aerial mycelium close to substratum : 

 Conidia: 0-septate, 3 per cent 



1-septate, 19 per cent, 17 x 3 (12-22 x 2.5-4)/* 



2-septate, 9 per cent 



3-septate, 43 per cent, 30 x 3.5 (17-42 x 3^.8) /* 



4-septate, 7 per cent 



5-septate, 18 per cent, 47x4.2 (35-55 x 3-5.2) /*, the thickest 

 50 x 5.9^ 



6-septate, 1 per cent 



7-septate, rare, the longest 75 x 4.8/* 



On hard potato agar, culture eleven days old ; conidia from thin pseudo- 

 pionnotes : 



Conidia: 1-septate, 3 per cent, 18 x 4.3/* (only a few measured) 

 2-septate, 2 per cent 

 3-septate, 20 per cent, 29x4.5 (20-35x4-6.5)/*, the broadest 



34 x 6.5/t 

 4-septate, 10 per cent
