He added that he had not been able to find the spores of the 

 second species, but assigned it to Aschersonia from its struc- 

 ture and general appearance. Seven figures were given 

 of Aschersonia taitensis. The pycnidia are shown as flask- 

 shaped in section, distinct below, but united by furrows above. 

 The stromata are discoid. The pycnospores in the figure are 

 three-septate, and the illustration of the hymenium does not 

 show any paraph yses. None of the figures shows a hypothal- 

 lus, but in the vertical section the stroma is slightly expanded 

 towards the base. 



The characterization of the genus was erroneoub on two 

 points. There is apparently nothing in the specimens to 

 justify the statement " primitus velo fugaci byssino concolori 

 tectum," though from the description of ^. taitensis one would 

 expect the presence of a hypothallus ; and the spores are 

 not triseptate, but quadriguttulate, as, indeed, Montagne's 

 original drawing shows. 



In Sylloge Generum Specierumque Cryptogamarum (1856) 

 Montague republished his description of the genus with slight 

 verbal alterations. In Saccardo, Sylloge Fungorum, III., 

 p. 619, the description reads : " Stroma carnosum, hemis- 

 phaericum, turbinatum, v. pulvinatum, Isete coloratum, 

 primitus velo fugaci byssino concolori tectum. Peiithecia 

 (seu locuH) stromate subimmersa membranacea, tenuissima, 

 erecta, fibroso cellulosa porisque late apertis (tandem rimose 

 confluentibus) pertusa. Basidia filiformia. Sporulae fusi- 

 formes hyalinae, continuse, subinde 3-4 guttulatse spurieque 

 septat3e.~Fungi phyllogeni, tropici, Hypocreis affines et 

 paralleli, sed ascia carentes."
