Gonidia pleurococcoidea, globosa, simplicia diam. O.ooe — 

 O.oio mm, saepe 2-cellulosa. In specimine a Schradero misso in 

 herb. Ach. perithecium vertice emergente, ceterum immersum, 

 maxima parte inferiore albidum, apice fusco-fuligineum, lateribus 

 rotundatis, nucleus jodo glaucescens vel dilute caerulescens, dein 

 glauco-fulvescens, sporae ellipsoideae aut oblongae, apicibus ro- 

 tundatis aut obtusis, long. O.020 — O.026 ( — O.013), crass. O.oos — 

 O.oio mm, 8:nae, distichae, decolores, simplices, paraphyses in 

 gelatinam diffluxae, striis indicatae. In specimine in Kaarina 

 lecto perithecium est globosum, vertice fusco- aut subrubricoso- 

 fuligineum, periphyses long. circ. O.030, crass. O.0015 mm, nucleus 

 jodo glaucescens, dein fulvescens vel in eodem apothecio partim 

 dilute sordideque violascens. Sec. specim. n. 3133 in herb. Nyl. 

 e Pyrenaeis conidia „bacillaria vel utroque apice incrassatula, 

 long. O.003 — O.0045, crass. O.007 mm". 



Obs. 1. Specimina orig. e Suecia Lichenis Scliraderi Ach. Lich.

 p. 114, Lich. Univ. p. 284, Syn. Lich. p. 93) ex herb. Ach. Hel- 

 singforsiae ablata sunt. Specimina in Germania a Schradero col- 

 lecta, „V. Schraderi" in herb. Ach. nominata, etiam in Lich. Univ. 

 p. 284 citata, ita sola specimina orig. V. rupestris Schrad. hucusque 

 cognita sunt. 



Obs. 2. Verrucaria rupestris var. oxydata Nyl., Herb. Mus. Fenn. 

 (1859) p. 93, in lapide dolomitico extus ferruginoso-rufescente ad So- 

 dankyla in Lapponia Kemensi ab Edv. Nylandro lecta, thallo endoli- 

 theo, KHO non reagente, peritheciis 0.4— 0. 35 mm latis, semiimmersis, 

 vertice rubricoso-fuscofuligineis, interne pallidis, nucleo jodo dilutis- 

 sime subroseo, sporis long. O.ois — O.025 mm ( — ,,0.02: mm" sec. Nyl. in 

 sched.), crass. O.oos- O.oio mm instructa est. V. marmorea (Scop.) Zahlbr. 

 thallo KHO aeruginoso-nigricante ab ea differt. Substratum etiam sub 

 alio lichene cum „var. oxydata" crescente eodem modo coloratum, quare 

 a thallo hie color non est productus. 



37. V. subfossans Vain. (n. sp.). 



Thallus endolitheus, indistinctus. Apothecia crebra, 

 epilithea aut substrato immersa foveolasque formantia, 

 vertice nigra. Perithecium subhemisphaericum, lat. circ. 

 0.J5 mm, superne fuligineum, dimidiatum, basi albidum, 

 lateribus haud productis, margine ostiolari haud prominente, 

 ostiolo minuto. Sporae oblongae ellipsoideaeve, long. O.013- 

 O.022, crass. O.006 — O.009 mm.
