Aleurina 101 



sculptured, 12 14 X 20-25 ix; spore-sculpturing taking the form 

 of reticulations which are often interrupted or broken ; paraphyses 

 enlarged at their apices, where they reach a diameter of 6 /i, 

 filled with orange granules. 



On soil among mosses (especially Polytrichum), apparently 

 growing on the dead leaves and often hidden by the living plants. 



Type locality: Europe. 



Distribution: New Hampshire and New York to Iowa; also 

 in Europe.

Doubtful and Excluded Species 



The genus Aleuria Is here restricted to those species in which the spores 

 become reticulate as used by Fuckel. The genus has been used in a much 

 broader sense by both Gillet and Boudier, so that many of the species treated 

 as Aleuria by those authors will be included in the present work with the 

 genus Peziza and other genera of the tribe Pezizeae.
