10 M. FOSLIE [1899 



Melobesia verrucata Crn. 

 Fl. Finist. p. 150. 



^ Melobesia farinosa Lamour. 



I have seen a small specimen distributed by Crouan under 

 the above name. It is attached to Phyllopliora rubens. I have 

 not had the opportunity of dissecting it, but a solitar}^ conceptacle 

 has been ex^mined, subconical but rather blunt, about 150 jj. in 

 diameter, with four-parted sporangia 50 — 55 /Jt long and 25 — 30 p- 

 broad. Therefore, I do not think to be wrong in referring it to 

 M. farinosa. In habit it rather much approaches L. corticiforme. 

 The form quoted by Crouan 1. c. occurring on Fucus not un- 

 likely belongs to DermatolitJion pustulatum. 



Melobesia myriocarpa Crn. 

 Fl. Finist. p. 150. 



= Melobesia zonalis (Crn.) F^osl. 



The specimen of this species'that I have seen almost covers 

 a piece of porcelain about 3 by 2 cm. The crust is more conti- 

 nuous and more regular than the above mentioned specimen of 

 M. zonalis, but otherwise fuUy agreeing wWh this, and provided 

 with conceptacles similar to those in the latter. There is no doubt 

 as regards the identity. It represents only a somewhat older spe- 

 cimen of the species. I keep the name M. zonalis, as this is re- 

 corded long before M. myriocarpa. 



Melobesia hapalidioides Crn. 

 Liste des Alg. mar. sec. Fl. Finist. p. 150. 



= Dermatolithon (Herpomenia^) hapalidioides (Crn.) 

 Fosl. 



f. typica. 



In Syst. Surv. Lith. I refei-red this species to a new genus 

 owing to the sporangia being accompanied by parapliyses. In 



1) Herpomenia contrary to Eudermatoliihon corresponds with Heteroderma 

 of the o-enus Melobesia.
