only — a habitat not recorded by M. Boudier ; his plant seems never- 

 theless to be identical with our own. Unfortixiiately, M. Boudier 

 does not give measurements of the sporidia, neglecting Dr. Nylander's 

 adx-ice in his treatise on the Peziza:! of Finmark, and thus depri\-ing 

 botanists of one valuable means of identification) ; A. LfveiUei, 

 Boud. ; A. pnrp1njroiii>orus, Fr. (is this .species really distinct from 

 A. immersus, P. ? The description by Fries accords in many re- 

 spects witli that of A. macrosporus, Cr., or A. immersus, P.). 



The genus Saccohohis has an hymenium dotted with black gra- 

 nules — the tips of the asci, which are less exserted than in AscohoJus. 

 The paraphyses are equal in length to the asci. -iVsci short, sub- 

 quadrate above and subcuneate below ; operculum subtriangular, 

 without an umbo. Sporidia eight, ha%-ing a smooth or slightly and 

 transversely rimosc epispore, enclosed in a common membrane. 

 The following species are included : — Sacfoholus Kerverni, Boud. ; 

 S. viohtscetts, Boud. ; S. neyJectus, Boud. (this species is very near if 

 not identical with Ascobohis depauperatus, B. & Br., Ann. Nat. Hist, 

 ser. 3. vol. xv. p. 448, t. 14. fig. 6) ; S. fjlohulifer, Boud. 



The following AscoboU of various authors are not incorporated in 

 M.Boudier's genera, from want of clearness in their characters : — 

 A. S2)h(rricus, Preuss. ; A. Daldinianiis, De Not.; A. rufo-pallidu!!, 

 Karst. ; A. Japponicxis, Karst. The AscoboU spurii of M. Boudier 

 follow. Thecotheius, having an erumpent hymenium, rough with 

 crystalline prominences (the tips of the much-exserted asci), filled 

 with hyaline sporidia ; Thecotheius Pelletieri, Boud., the only species. 

 Ryparohitis has a very minute receptacle, few paraphyses, and large 

 many-spored asci, opening by a large convex operculum not much 

 exserted: Ryparobius brunneus, Boud., R. Cookei, Boud., R. fe- 

 liniis, Boud., R. duhius, Boud., and R. myriosponis, Boud., consti- 

 tute the species of this genus. The genus Ascophcoius follows, with 

 an hymenium papillate with crystals from the slightly exserted asci, 

 equalling the paraphyses in length, and enclosing eight, or in one 

 species sixteen, ovate-oblong, hyaline sporidia. The species are : — 

 Ascophanits minutissiiiuis, Boud. ; A. C'oemansii, Boud., which seems 

 not to differ from Ascobohis microsporus, B. & Br. 7. c. p. 449, except 

 in the colour of the mature sporidia; (we may observe that Ascobolus 

 pihstis, Bond., or A. ciUatus of some writers, has sporidia of a dark 

 violet-colour when mature, which 3J. Boudier does not appear to 

 have noticed, as it would exclude it from his genus Ascophamis ;) 

 A. gramdiformis, Boud. ; A. argenteiis, Boud. ; A. vicinus, Boud. ; 

 A. ochraceus, Boud. ; A. sexdecemsporus, Boud. ; A. aurora, Boud. ; 

 A. cinereus, Boud. ; A. cnmeus, Boud., which comes very near to 

 Ascobolus testaceus, Wall. ; A. saccharimis, Boud. ; A. difformis, 

 Boud., synonymous with Ascobolus tcstaceus, Karst., and possibly 

 identical, M. Boudier thinks, with Ascobolus saccharinus, Currey ; 

 A. papilhitus, Boud. ; A. ciliatus, Boud. ; and A. pilosus, Boud. 

 Among spurious and doubtful AscoboU is placed A. miniattis, 

 Preuss. And excluded species foUow, viz. : — A. pulcheri-imus, Ct., 

 doubtfully referred to Peziza subhirsuta or P. stercorea ; A. insignis, 

 Cr., referred to the same group of Pezizae; A. Persoonii, Cr., re-
