120 BRITISH FUNGI. 



Peziza (Humaria) vivida. Nyl. 

 Solitary or gregarious, fleshy, stipitate, cups at first clavate,tlien 

 open and cupshaped, disc concave, red, becoming somewhat brown- 

 ish ; externally paler and fibrillose, stem thick, expanding into the 

 cup ; asci clavate. Sporidia elliptical, with 1-2 nuclei, epispore 

 delicately granulated. — Nylander in Flora (1865) ji. 467. Rabh.

Amongst moss. "Wiltshire (C. E. B). Scotland (in herb. Edin.) 



Cups 2-4 lines broad and high. Sporidia -025 X -012 m'.m. 

 This is one of the species which has been confounded with P.poly- 

 trichi and P. leucoloma. In the Edinburgh Herbarium it is referred 

 to the latter by Dr. Mougeot. The fibrillose coating of the cnp 

 and the large granular sporidia are sufficient to distinguish it from 

 any of its immediate allies. It would appear that the true P. 

 Polytrichi, Schum., is a smaller plant, and has smooth subglobose' 

 sporidia. Most probably the Peziza leucoloma of Rabenhurst's 

 " Mycologia," and of Nylander and Karsten are also P. Polytrichi, 

 with sporidia -Oll-'OIS m.m. diameter. The Peziza Polytrichi of 

 Karsten and also of Nylander is Peziza Crouani, C. {Ascobolus 

 Crouani oi the "Handbook"), with reticulated globose sporidia. 

 The specimens published by Fuckel as P. leucoloma, appear to be 

 identical with those which Messrs. Berkeley and .Broome had in 

 view as that species (Ann. Nat. Hist., No. 1156*), with elliptical 

 nucleated sporidia, -02 X -01 m.m. The figure in " Grevillea" 

 {iii.Jig. 73) is from Fuckel's plant. In order to render the cha- 

 racter of the fruit in the three species cleas and distinct, we will 

 summarise our conclusions, thus : — 



P. vivida, Nyl. Sporidia elliptic, granulated, *02.j X "012 m.m. 



P. leucoloma, P. Sporidia elliptic, smooth, -02 X -01 m.m. 



P. Polytrichi, Sch. Sporidia globose, smooth, -Oil — "013 m.m. 



Peziza (Humaxia) exidiifozmis. B. & Br. 



Orbicular, lurid purple ; margin elevated, inflexed, stem incras- 

 sated upwards, hymenium cribrose. Sporidia broadly elliptical, 

 binucleate, paraphyses slightly clavate. — B. ^ Br., Ann. N.H., No. 

 1480. 



On silver sand, and rotten wood. 



Two lines or more broad. Contracting very much when dry. 

 Sporidia (-0007 X -0004 in.; -017 X -01 m.m. 



Peziza (Humazia) fusispora. B. 



Gregarious, here and there crowded, oi-ange- yellow, hemispherical, 

 slightly concave, or quite flat, with a delicate membranous edge, 

 obscurely tomentose, fixed to the soil by a little down. Asci cylin- 

 drical, obtuse, sporidia elliptic, attenuated slightly at either end, 

 and binucleate. Berk, in " Hook. Journ.," 1846. — B'. ^ Br., Ann. 

 N. Hist., No. 1481. ("Grevillea," Hi., fig. 84.)
