dimidiata, paraphysibus distinctis. Spore in ascis cylindraceis dilute fusce ellip- 
soidez 8—5-septatee, longit. 023 mm., crassit. 008 mm. Ad cortices arborum. 
VERRUCARIA SAXICOLA, Kn. (Plate XXXVIII. fig. 2.) 
Thallus luteo-olivaceus tenuissimus v. nullus. Apothecia parvula hemispheerica, peri- 
. thecio carbonaceo integro, ostiolo inconspicuo, nucleo subgloboso hyalino, paraphysi-

Thallus tenuis fulvo-fuscus v. cinereo-fuscus opacus continuus indeterminatus. Аро- 
thecia nigra prominula (madefacta szepe innata) hemispheerica integra, paraphysibus

Probably this may be У. aspistea, Ach.; but there is much confusion about Acharius's 
plant. Nylander remarks “Esse videtur modo V. nitida minor, sporis minoribus." 
Montagne describes У. aspistea, Ach., “sporis magnis ellipticis 16-annulatis, annulis 
pauci-cellulosis;" he adds that V. aspistea of Eschweiler is incorrectly named, and he 
has therefore named Eschweiler’s plant V. Eschweileri with “spora binucleolata." 
Acharius describes his Lichen as having a polished yellowish thallus, limited by a black 
line, in these and other characters differing from the New-Zealand Lichen.
