THELOCARPACE^. 



Horizontal thallus wanting. Algal cells Pleurococcus or Proto- 

 cocciis. Perithecia superficial, surrounded by a gonidial sheath, 

 completely enclosed or opening by a pore ; asci with numerous 

 simple or septate spores. 



A somewhat peculiar and aberrant Order. The single genus 

 Thelocarpon was included by Nylander in the Pyrenoca/rpei (Mem. 

 Soc. Soi. Nat. Cherb. v. p. 135 (1857) ). Later it was transferred to 

 the fungi by Eehm (Hedwigia xxx. p. 3 (1891) ), who regarded it as one 

 of the Hypocreaceoe. A. Zahlbruckner, who rejects this classification 

 on account of the well-defined gonidial structure, has included it in 

 the AcarosporacecB, along with other genera distinguished by many- 

 spored asci (see p. 107).

 ii. p. 338 (1854), emend, in Flora Ivi. p. 299 (1873). (PI. 56.) 



Thallus forming small scattered or congregate verrucse, each 

 one enclosing a perithecium. Perithecia almost globose, com- 

 pletely enclosed or opening above by a pore ; perithecial wall 

 colourless, slightly developed ; paraphyses slender, simple or 

 branched or wanting ; asci elongate, clavate or ventricose-fusi- 

 form, many-spored ; spores minute, colourless, simple or pseudo- 

 septate. Spermogones unknown.

 scattered or aggregate verrucse, yellowish-green. Perithecia en- 

 closed in the verrucse, soft, minute, globose, citrine- or greenish- 

 yellow, the ostiole slightly depressed and inconspicuous ; perithecial 

 wall colourless; paraphyses scanty, slender, branched, shorter 

 than the asci ; asci flask-shaped, broad in the middle, narrower 

 upwards, about 0,100 mm. long, 0,012 mm. thick; spores minute,
