Distr. In latere rupis subcalcariae in Kaukasalo in par. 



Finby (Vain.) et ad saxum gneissaceum in Kuusisto (A. Kull- 



hem) in Regione Aboensi. 



Facie externa V. latebrosam in memoriam revocans, sed 

 thallo tenuiore et apotheciis minoribus. Etiam cum V. obni- 

 grescente facile commiscitur, at maxime affinis V. fuscoluridae, 

 quae colore thalli ab ea distinguitur. — Thallus superne plecten- 

 parenchymaticus, cellulis anguloso-rotundatis, leptodermaticis, 

 O.002 — 0.003 mm latis. Gonidia cellulis vulgo globosis, diam. 

 0.004 — 0.008 mm, saepe glomerulosa, membrana modice incrassata. 

 Perithecium sub microsc. fuscorubricoso-fuligineum, ostiolo circ. 

 0.oi8 mm lato. Nucleus jodo leviter fulvo-rubescens aut partim 

 leviter caerulescens. Paraphyses in gelatinam diffluxae, striis 

 indicatae. Asci clavati aut subventricosi, membrana gelatinosa, 

 sat tenui aut modice incrassata. Sporae 8:nae, distichae, simplices, 

 decolores, apicibus rotundatis. 



F. Kiantensis Vain. Apothecia vertice plus minusve late 

 denudato nigricanteque, primum minus diu tota amphithecio 

 thallino obducta. Ostrobotnia Kajanensis: Ad saxa chloritico- 

 schistosa in rivulo prope Kiannanniemi in par. Kianta (Vain.), 

 una cum V. umbrinula var. degrediente. — In V. fuscoluridam 

 accedens, sed colore thalli potius (at haud omnino) cum V. 

 cinereolurida congruens. Perithecium dimidiatum, basi albidum. 

 Thallus continuus, laevigatus, obscure cinerascens. 



34. V. fuscolurida Vain. (n. sp.). 



Thallus sat tenuis, subcontinuus aut leviter rimulosus, 

 laevigatus, lurido-fuscescens, opacus, hypothallo indistincto. 

 Apothecia sat crebra, verrucas formantia subhemisphaericas, 

 0.2 — 0.3 mm latas, basin versus sensim dilatatas et amphi- 

 thecio thallino tenui, thallo concolore obductas, vertice 

 anguste aut demum late denudatas nigricantesque, sat opa- 

 cas. Perithecium fusco- aut subrubricoso-fuligineum, basi 

 albidum, depresso-subglobosum, lateribus rotundatis, margine 

 ostiolari vulgo leviter prominente, ostiolo minuto, haud foveo- 

 lato. Sporae oblongae, ,,long. O.024 — O.025, crass. O.010— O.on mm" 

 (sec. annot. Nyl.). 



Distr. Ad saxa granitica (forsan littoralia) in Alandia 

 (Edvin Nylander, ,,V. margacea" sec. determ. W. Nylandri 

 in mus. Fenn.).
