aliis cylindricis sporidiis octonis ellipticis utrinque appendi- 

 culatis. 



On dead twigs of holly. Shooter^s Hill, F. Currie, Esq. Near 

 Bath. 



A figure of the asci and sporidia of this curious species will be 

 shortly given in the ' Gardeners^ Chronicle.^ Similar fruit occurs 

 in Nectria Cucurbitula. 



782. Aylographum amplum, n. s. Peritheciis congregatis 

 congestisve subdepressis furcatis ramosisque. On decaying stems 

 of Rubi, Twycross, Rev. A. Bloxam. 



Distinguished by the perithecia being crowded together in the 

 most perfect specimens and by their comparatively large size. 

 Those before us are not so perfect as could be wished, but the 

 species is unrecorded, and the genus new to this country. 



Bloxamia, n. g. 



Peridium deorsum persistens, sursum delicatissimum hyalinum 

 evanescens demum excipuliforme ; sporidia quadrata tubulis 

 arete congestis enata. <.>enus curiosissimum anomalum, 

 Dichosporio proximnm, asci enim ni fallimur non typici, 

 Myxormiam quodammodo in memoriam revocans. 



783. Bloxamia truncata, n. s. On dead Wych elm, Bath- 

 easton, Feb. 1852. 



Perithecia punctiform, often slightly elongated, depressed, 

 with vertical sides, firmer below and persistent, extremely 

 delicate, white and evanescent above. Hymenium consisting of 

 closely packed tubes which produce a row of subquadrate spores, 

 •0001 wide, -000125 long. 



This very curious plant in many respects agrees with Nees von 

 Esenbeck^s Dichosporium, but Dittmar could not have overlooked 

 the tubes in which the spores are generated. We do not regard 

 these tubes as typical asci, but of the same nature as those in 

 Sporoschisma, and, if so, it w ill on the one side be connected with 

 Conoplea of Fries, and on the other with Myrothecium through 

 Myxormia. The spores closely resemble those of Scopinella 

 barbata when the light is indistinct, but under a very superior 

 microscope no division is apparent. 



Plate XVI. fig. 17. a- Plant, natural size; b. magnified; c. mass of 

 tubes ; d. two of the tubes separate ; e. spores. All but the first more or 

 less magnified. 



784. Antennaria semiovata, n. s. Floccis fertilibus erectis brevi- 

 bns ramosis; articulis torulosis laevibus; pycnidiis semiovatis; peri- 

 theciis curvis acuminatis. On the leaves of Filix mas, near Bath, 

 Sept. 1853.
