hypocrklla and aschersonta. 263 



Species Dubi^. 



Hypocrella? Gardeniae P. Henn., Hedwigia (1893), p. 223.— 

 " Stromata hypophyila pulviiiata, pallide brunnca, carnulosa, 

 1 mm. diam., .subiculo pallido insidentia : asci non visi : 

 spoiidia in articulos hyalines fusoideis, 8-10 X 3 \x, dilabentia. 

 In foliis Gardeniae fioridse in horto Bogor, Java." 



The note of interrogation is Hemiings's. After the description 

 Hennings wrote that, although he had inade several examinations 

 of the fungus, he had not succeeded in finding asci. On the other 

 hand, he found spores in abundance. He was of opinion that the 

 fungus belonged to Hypocrella, judging from the character of the 

 stroma, which was exactly the same as that of Hypocrella semen 

 Bres., though the spores appeared to be produced in a different 

 manner. 



ThetypespecimenisnotinHerb. Berlin. Hypocrella semeni&not 

 a Hypocrella, but a Discomycete, and if the supposed Hypocrella 

 (Jardeniae resembled it, it may doubtless be rejected. But it would 

 seem possible that the specimen may hav e been Aschersonia Cojfese. 



Hypocrella Engleriana Koord., Bot. Untersuch. (1907), 

 p. 177. — " Stromatibus carnosis, pulvinatis, basi constrictis, 

 extusfuscis, • 5-1 mm. cr., hypophyllis : peritheciis immersis ; 

 ascis cylindraceis, 60-65 [x longLs, 4-5 ^. latis, 8-sporis ; 

 sporidiis filiformibus asci longitudinem subsequantibus, 1 ;j. 

 latis, dense minute septulatis ac guttiilatis, tarde in articulos 

 seeedentibus. In foliis emortuis Mangiferse indicse Java." 



The type specimen in Herb. Berlin bears a note which states 

 tliat the fitictifications are entii'ely immersed ; that may, however, 

 refer to the perithecia. The leaf bears two minute, black, car- 

 bonaceous bodies, piolvinate, not constricted below ; it is possible 

 that these may be effete Hypocrella, but they are too old for 

 determination. There is nothing now which corresponds to 

 Koorder's figures. 



Hypocrella Tamoneae Earle, Mycologia, II,, p. 87. — " Stro- 

 mata scattered, hypophyllous, 1-1*5 mm. in diameter, black 

 (at least in aged specimens), suborbicular, crust-like, super- 

 licial ; perithecia crowded, prominent, finally collapsing, 

 200-250 ^- diameter ; ostiola perforate, large, somewhat 

 irregular : asci cylindrical, short -stipitate, 80-100 x 7-8 ^ ; 

 spores thread-like, very slender, equalling in length the ascus, 

 spirally coiled, about 80 x • 75 [ji, : paraphyses numerous. 

 On living leaves of Tamonea sp., Porto Rico." 



In its collapsible perithecia, and in the presence of paraphyses 

 in the perithecium, this species differs from every Hypocrella 

 known. Its reference to Hypocrella appears very doubtful.
