550. F. foeni, n. s. Hypliasmate parco floccis fertilibus bre- 

 vissimis sporis oblongis rectis obtusis 1-2-septatis. On the cut 

 surface of a hay stalky Apethope, Norths., Dec. 1848. 



Orange-red, spreading in wide patches many feet in width. 

 Hyphasma creeping, sparingly articulate. Fertile flocci very 

 short. Spores oblong, obtuse at either extremity, 1-2-septate. 



Agreeing in habit with F. avenaceum, but differing from all 

 other species in the straight obtuse oblong spores. 



*551. Psilonia Arundinis, Desm. Exs. no. 460 = Psilonia Fes- 

 tucce, Jjihevt = Chloridiiim Festucce, Corda. Spye Park, on Carex 

 paniculata, Feb. 1850. It is not uncommon on Ai^undo Phrag- 

 mites. 



We can see no difference between the plant of M. Desmazieres 

 and that of Madame Libert, except that the spores in the latter 

 are rather longer and more curved. The colour and general ap- 

 pearance are exactly the same. 



552. Helvella Ej}hippium,Jjev. Ann. d. Sc. ser.2. vol. xvi. p. 240; 

 Desm. Exs. no. 1414. On the ground in woods and groves, spring 

 and autumn : common. 



This species is very near to H. elastica, and differs principally 

 in its dwarf size and decidedly velvety coat. Schseff. tab. 321 is 

 evidently the same thing. This figure does not seem to be quoted 

 by Fries. 



553. Morchella esculenta, h. conica, Fr. Syst. Myc. vol. ii. p. 7. 

 Woods at Westbury near Bristol. 



This is considered as a distinct species by Persoon and other 

 authors, but it seems to us nothing more than a well-marked 

 variety. 



554. Peziza Babingtonii, n. s. Minor; supra con vexamm-ino- 

 fusca margine affixa, subtus concava pallide aquosa rugosiuscula 

 fibrillis obsoletis. On rotten wood, Grace Dieu Wood, Leicester- 

 shire, Rev. C. Babington. 



Cup half an inch or more broad, contracting greatly in drying, 

 irregular in outline, convex above, mouse-brown, concave be- 

 neath and slightly wrinkled, pale watery brown, fixed by the 

 border. Asci linear, spores broadly elliptic. Paraphyses linear, 

 their apices clavate. 



This curious production has occurred only once, and resembles 

 a Rhizina more than any Peziza, but it has not_ the peculiar 

 roots of that genus. We are unwilling to pass it by altogether, 

 hoping that some one may meet with it and give more perfect 

 information. It should be observed that the spores in B. Icevi- 

 gata are naviculaeform. 



555. P. viridaria, n. s. Media mycelio expanso lanoso albo; 

 cupulis primum globosis demum hemisphsericis sero expansis 

 aquose cinereis. On damp walls of a greenhouse. King's Cliffe,
