Thallus margine anguste laciniatus, lacinulis partim isidio- 
ideis, saepe partim etiam lamina isidipsa, superne pseudocyphellis 
destitutus, glaucescens, KHO non reagens, sat laevigatus, intus 
albus, nec KHO nec CaCIaOa nec his reagentiis unitis reagens, 
subtus obscuratus, ambitum versus pallidus, rhizinis concolo- 
ribus, crebris, brevibus instructus, aut partim ambitum versus 
denudatus, pseudocyphellis parvis, punctiformibus, haud aut 
leviter prominentibus, albis. Apothecia in lamina thalli sparsa, 
1.7-1 mm lata, disco fusco, concavo aut piano, margine sat tenui, 
integro, superne disco concolore aut pallido. Excipuium extus 
leviter verruculosum, glabrum, gonidia continens, in margine 
gonidiis destitutum. Hypothecium fulvescens aut fulvescenti- 
pallidum. Epithecium fulvo-rufescens. Sporae 8-nae, disti- 
chae, fusiformes, apicibus obtusis, 1-septatae, raro 2-septatae, 
rufescentes, long. 0.020-0.023, crass. 0.007-0.010 mm. Gonidia 
pleurococcacea, diam. 0.005-0.010 mm, flavescentia, simplicia. 
Habitu similis est “Stictae multifidae Laur.” (no. 33530 in herb. 
Nyl., ex insulis Viti), cujus medulla autem KHO et CaClaOj 
unitis rubescens. P. subvariabilis (Nyl.) reactione cum P. mul- 
tipartita congruens, at thallo superne et interne pallido et subtus 
late denudato ab ea diftert. S. variabilis var. polyschista Mey. 
& Flot., in Manila lecta, ex opinione Muell.-Arg. ad P. sub- 
variabilem pertinet, at reactione thalli defecte cognita.
