Distr. Ad saxa micaceo-schistosa in Maanselka (Suolo- 

 selka) in Lapponia Kemensi (G. Selin). 



Intermedia est inter genera Polyblastiae et Thelidii. Peri- 

 thecium KHO non reagens. Nucleus albidus, parce resinoso- 

 guttulosus, jodo roseus, haud caerulescens. Periphyses sat 

 numerosae, constipatae, simplices, crebre septatae, long. circ. 

 O.020 — 0.oi5, crass. O.0015 mm, membrana tenui. Paraphyses in 

 gelatinam diffluxae, cavitates striis paucis brevibusque indicatae. 

 Asci clavati, long. circ. 0.065, crass. O.024 — O.028 mm, membrana 

 modice aut primum apice bene incrassata. Sporae distichae, 

 ellipsoideae oblongaeve, apicibus rotundatis aut raro obtusis, 

 membrana sat tenui, haud gelatinosa. Inter sporas simplices 

 numerosissimas lantum 2 sporae 3-septatae et nullae submurales 

 in duobus apotheciis adfuerunt. Gonidia pleurococcoidea, saepe 

 2-cellulosa aut simplicia. Gonidia hymenialia nulla. — Sporas 

 submurales Nyl. etiam in speciminibus Hungaricis secund. annot. 

 suas vidit. Ibi quoque tantum sporas simplices et nonnullas 

 3-septatas inveni. In tali casu autem observationes Nylandri 

 non sunt dubiosae.
