Boudier more fortunate in his endeavours to confirm the views of 

 M.Vorouin (Abhandlungen der Senckenbergischen naturforschenden 

 Gesellschaft, 1805, pp. 333, 334) ; but he saw the organs named 

 "scolecites" by M.Tulasne (Ann. Sci. Nat. ser. 5. vol. vi. p. 211-220). 

 He considers that the fertilization of the Ascoboli is still involved in 

 much obscurity. 



In arranging his materials systematically, he regards the AscohoU 

 as a division of the Pezizce characterized by asci furnished with 

 round or sub triangular opercula projecting above the hymenium 

 when nearly mature, and sporidia clothed with a waxy, coloured 

 cpispore — or hyaline, and then having a membranaceous one, not gra- 

 nular within nor filled ■\\dth oil-globules. He divides the old genus 

 Ascoholus into two principal sections, consisting of the true, and the 

 spurious or pezizoid species, deriving his characters from the organs 

 of fructification : — the genuine, with coloured sporidia and projecting 

 asci ; the spurious, having hyaline sporidia and asci generally little 

 exserted, and consequently an hymeiiial surface only slightly papil- 

 late. These two sections are distributed into six genera, viz. Ange- 

 lina, Ascoholus, Saccoholus, Tliecotheius, Kyparohius, and Ascophanus. 

 The first contains only Ascoholus conglomcratus, Schwein. The last 

 five are distinguished by the shape and position of the paraphyses 

 and asci, and the nature and arrangement of the sporidia. The 

 characters essential to the group M. Boudier considers to be an 

 hymenium papillate with projecting, coloured, or hyaline asci, which 

 oj^en by an apical, round or subtriangular operculum, and sporicha 

 rimose, with a coloured epispore, or with a membranaceous one, and 

 then hyaline, not granular within, with a single nucleus, and with- 

 out oil-globules. The author is thus compelled to exclude certain 

 species, as Ascoholus p^dclierrimus, Cr., Ascohohis Crouani, Cooke, 

 and others. A. Crouani, Cooke, is referred to the section Ilumaria 

 of the Fezizce, on account of the globules present in the sporidia ; 

 but a reference to the figure of the fruit in vol. xxiv. of the ' Lin- 

 nean Transactions,' p. 495, pi. 51, shows that the globules in ques- 

 tion become eventually reticulations, or, at least, that they are not 

 visible in the mature state of the sporidia. Nor is it very evident 

 wherein Ascohohis testaeeus, Wallr., differs from Ascoplianus carneus, 

 Bond. pi. 12. fig. 38. The genus Ascoholus is restricted to those 

 species with much-exscrted asci, conspicuous for their dark tips 

 (from the colour of the sporidia) above the rest of the hymenium, 

 opening by a round and umbonate operculum, and enclosing eight 

 longitudinally rimose, free siwridia, which are either naked or ad- 

 herent laterally to a membrane, or each enclosed separately and 

 then subaggregate or easUy separating, and paraphyses slender and 

 longer than the asci. 



The following species are included : — Ascoholus lir/natilis, A. & S., 

 A. Crouani, Boud. (the name having been given to A. miniatus, Cr., 

 by Mr. Cooke, it adds to the confusion to have it again applied to 

 another species) ; A. denudatus, Fr. ; A. viridis, Currey ; A. furfu- 

 raceus, P. ; A. vinosus, Berk. ; A. cubensis, B. & C. ; A. oirur/ineus, 

 Fr. ; yl. glaher, P. (this species has occurred to us on rabbits' dung
