206 FUNGI. [Peziza. 



On SplacJinum mnioides, Mr. Arnoti.^Pkmt ^— f of a line high. 

 " Cup at first ovate, closed, then urceolate, of a soft waxy consistence, 

 margin quite entire ; when <\vy scarlet, j)ersistent." Kl. MSS. In 

 the two last points the present plant differs from the description of 

 Fries, who says that when dry it acquires a brownish tinge and is sub- 

 evanescent. 



92. p, xantJiostigma, Fr. [golden-dot Peziza) ; sessile minute 

 submembranaceous smooth concave orbicular golden yellow. 

 Fr. Ohs. I, p. 166. Si/st. Myc. v. 2. p, 146. 



On rotting fir-wood. Captain Carmichael — Distinguished from 

 P. chri/socoma by its more hollow thinner cup, and less tender con- 

 sistence. I have however gatiiered, on soft decorticated oak-branches, 

 a species equally minute, but of a more tawny yellow and less excavated, 

 almost exactly intermediate. P. vinosa, Purt. ! 3ISS., as far I can 

 judge from very imperfect specimens, appears to be a form of the 

 present species. 



93. P. leucostigma, Fr. (ivliite-dot Peziza); sessile minute 

 submembranaceous smootli nearly plane white, disc with a 

 slight cinereous tinge. Fr. Obs. \. p. 165. Syst. Myc. v. 2. 

 p. 146. 



On soft rotten wood ; common. — Very minute, dirty-yellow when 

 dry. Scattered, at first appearing under the form of an urceolate dot, 

 in which state it appears under a powerful lens most minutely rugulose 

 and fixed down by a few delicate white threads, then quite flat with a 

 narrow border, white with the slightest possible cinereous tinge in the 

 centre ; in decay dirty-yellow or even grey. Not more than ^ a line 

 broad. Possibly the plant I have in view may be only a state of the 

 next species, as the cinereous tinge is so slight ; but it appears to differ 

 in several points. 



94. P. vulgaris, Fr. (common Peziza) ; sessile subcsespitose 

 membranaceous soft smooth dirty-white, at length pallid. Fr, 

 Syst. Myc. v. 2. p. 146 — ,S. diaphana ; scattered, urceolate, 

 then flat of a semi-transparent dirty- white or brownish. Sow, 

 U 389./. 7. 



/3. On the under-side of rotten sticks. Soicerhy. 



95. P. erumpens, Grev. (sycamore-petiole Peziza) ; minute of 

 a waxy-watery consistence smooth sessile grey erumpent. 

 Grev. So. Crypt. FL t. 99. 



" On sycamore petioles. Late in autumn. Auchindenny woods, 

 near Edinburgh. — Resembling to the naked eye an Hysterium, when 

 dry ; in moist weather distending the small slit in the back of the 

 petiole, till it attains its round form, when the margin projects over the 

 edge of the fissure." Grev. I. c. Surely distinct from P. vulgaris by 

 its peculiar habit. 



96. P. punctata, Grev. (yellow-dot Peziza) ; bright yellow 

 very minute gregarious punctiform globular, at length plane or 

 subconvex, margin minutely crenate. Grev. Fl. Ed. p. 424.— 

 P. pmictiformis, Grev. Sc. Crypt. Fl. t. 63. 



On dead oak and beech leaves. Balmuto, near Edinburgh.
