as the peritliecia ai'e indicated by the Httle dimples in the trun- 

 cate apex. 



591. Hypocrea myrmecophila, Cesati, Rab. Exa. no. 1033. 

 " Ochroleuca, stipite filiformi tenacello ; clavula ovoidea ad 

 basin sterili, superue costata acutiuscula e peritheciorum summo 

 ostiolo gibberulosa." Leigh Wood, Somerset, INIay, on some 

 species of Ichneumon. 



A single specimen only of this pretty species occurred at Leigh 

 Wood, exactly according with the individuals published by Raben- 

 horst and others gathered at Breschia by Cesati, communicated 

 by De Notaris. 



592. H. farinosa, n. s. Late expansa Candida, peritheciis con- 

 fertis hyalinis farinosis. On fallen branches, Milton, Norths., Mr. 

 Henderson ; King's Cliffe. A more downy form occurred at B&ch 

 Hall, Chester, on decayed Stereum, July 1848. 



Spi'eading for some inches over decayed wood, on which it 

 forms a thin white coat. Peritliecia minute, subglobose, hyaline, 

 nearly collapsed in the centre when dry, growing from a white 

 mealy subiculum ; at tirst delicately cottony. Asci filiform, con- 

 taining sixteen elliptic sporidia. 



A very pretty little species resembling H. hyalina, but far less 

 compact. The older individuals acquire a dull yellowish tinge. 



593. H.floccosa, Fr. Summa, p. 564. On. Agaricus torminosus, 

 King's Cliffe. 



594. H. luteovirens, Fr. /. c. On Boletus edulis, Laxton, 

 Norths. 



595. Sphceria marginata, Schwein. Joum. of Ac. tab. 3. fig. 8. 

 On wood in the great stove at Chatsworth, Mr. R. Scott. 



The wood on which this species was developed had merely 

 been placed in the stove, and was not of foreign growth. The 

 perithecia agree precisely with those of the American species, 

 except that they are somewhat smaller, as are also the sporidia. 

 We have however no doubt about the species, which is veiy va- 

 riable, and the sporidia are known to vary in different indivi- 

 duals of Sphceria which have been grown under different cir- 

 cumstances. The sporidia are sometimes separated by a globose 

 cell like the connecting cells in Anabaina. This structure occurs 

 in other species occasionally. 



596. Sph. coprophila, Fr. in Kz. Myc. Heft 2. p. 38. S. incana, 

 Stephens in Ann. of Nat. Hist. Ser.l.vol.iv. p.252. On cow-dung 

 in dense patches, Stapleton Wood, Bristol, H. 0. Stephens, Esq. 



A very pretty species, much smaller, but resembling S. con- 

 fluens, Tode. Asci clavate ; sporidia filiform, flexuous, containing 

 a row of nuclei. 



597. S. confluens, Tode, Fung. Meek. t. 10. fig. 87. On 

 decayed wood, as oak, willow, &c., near Bristol.
