Zu Didymosphaeria habe ich provisorisch alle jene 

 Flechtenparasiten gerechnet, die mehr weniger eingesenkte 

 Perithecien und deutliche Paraphysen und constant zwei- 

 zellige Sporen haben; ich fllhre von diesen die deutschen 



Arten bier an: 



Didymosphaeria bryonthae (Arnold). = Endo- 



coccus bryontbae Arnold in Licbenol. Fragmente XVL 



pag. 26. tat*. II. Fig. 15 in Flora 1874. 



Perithecia gregaria, minuta, subglobosa, valde convexa, 

 prominula, vertice pertusa. Asci fere cylindracei (sec. icon, 

 clavati, deorsura stipitiforme attenuati)^ 8-spori. Paraphyses 

 distinctae, tenues, capillarcs. Sporae inordinatae, oblongae 

 vel clavatae, bicellulares, baud vol pariim constrictae, pallide 

 fuscidulaej 12—16 f^t longae, 4 — 5 /t crassae. 



In disco apotheciorum Lecanorae subfuscae var. 



bryonthae. 



Didymosphaeria microstictica (Leighton). 



Verrucaria microstictica Leight., Lichen. Flora of Great- 

 Britain, Edit. III. pag, 493. 



Perithecia minutissima, plus minusve immersa, globosa^ 

 vertice plano-convexo^ pertuso, fusco-atra. Asci cylindrici, 

 breve stipitati, 8-spori, 78—88 ^ti longi; 10 ^i crassi. Sporae 

 mono-vel subdistichae, elliptico-oblongae, bicellalares, medio 

 constrictae, atrae, opacae, 14 ,« longae, 7 /< crassae. Para- 

 physes numerosae, liliformes, subramosae. 



In thallo Acarosporae fuscatae et cervinae. 



Didymosphaeria (V) Sauterl (Korber) = Poly- 

 coccum iSauteri Korber, Parerga pag. 470. 



Perithecia minutissima, conferte stipata, maciilas subatras 

 formantla, demum saepe confluentia, semiimmersa, globosa, 

 ostiolo umbonato, fusco-atra. Asci cylindracei, substipitati, 

 8-spori, ca. 100 iU longi, 15— 16 ^w crassi. Sporae raonostichae, 

 dacryoideae, cellula superior! multo latiori longiorique, 

 fuscae, 16 — 19 /w longae, 9— 10;5 ^i crassae. 



In Stereocaulone condensato et alpino atque in Lecidea 



fumosa. 



Obiger Diagnose liegen die in Rabenhorst's Lichenes 

 europaei 182 ausgegebenen Original-Exemplare zu Grunde. 

 Nach Korber und Ohlert sind die Sporen nur 12—15^ Jang, 



8 — 9 jti dick.
