MOLLISIA. 211 



brown, externally rufous-brown, about J- mm. across ; exci- 

 pulum parenchymatous, cortical cells pale olive, polygonal, 

 and about 6^8 fi across near the base, becoming long and 

 narrow upwards, and running out into free, parallel liyphae 

 of various lengths to form the pale, irregular margin ; asci 

 almost cylindrical, apex narrowed, base truncate, hardly 

 narrowed, 8-spored ; spores hyaline, continuous, cylindric- 

 fusoid, 7-8 X 1 /*, irregularly 2-seriate, paraphyses very 

 slender, hyaline. 



On dead nettle stems lying in very damp places.

Scattered or gregarious, very minute, ^— ^ mm. across, 

 sessile, globose and closed at first then concave, finally 

 almost plane, ivory-white, almost translucent ; margin white, 

 minutely irregular ; externally slightly pruinose, thin and 

 delicate ; excipulum delicately parenchymatous, cortical cells 

 polygonal and about 5 /* across near the base, becoming very 

 narrow and elongated upwards, running into slender, parallel 

 hyphae of various lengths at the margin ; asci cylindric- 

 clavate, apex narrowed, base truncate, scarcely constricted, 

 8-spored; spores irregularly 2-seriate, hyaline, continuous, 

 narrowly cylindric-fusiform, straight or slightly bent, 

 8-12 X 1 • 5-2 /*. ; paraphyses hyaline ; about 2 /* thick, apex

Peziza effugiens, Eoberge, Ann. Sci. Nat., 1853, p. 19. 



Pseudohelotium effugiens, Sacc, SylL, viii., n. 1225. 



On dead stems of herbaceous plants, &c. Eoberge's speci- 

 men is on dead stem of Clematis erecta. 



Distinguished from allied species by the somewhat stout, 

 very straight paraphyses with pointed tips. The ascophores 

 burst through the cuticle, but are not truly erumpent.
