wenig bekannten Buche steht, und ich mich doch wiederholt auf dieselbe beziehen muss, so 

 wird es zweckmässig sein, sie hier zu reproduciren. 



Exormotheca n. g. 



Eeceptaculum femineum primo subglobosum integrum, subtus pro insertione pedun- 

 culi perforatum demum subturbinatum, loculis 1 — 4 protrusione capsulae horizontali tubu- 

 losis, apice poro dilatato dehiscentibus. Perianthium nuUum. Calyptra brevis persistens 

 inclusa. Capsula dentibus irregularibus 4 dehiscens in pedunculo brevi emergens. 



E. pustulosa. Frondes caespitosae, dichotomae, humidae superficie planiusculae, 

 siccae autem marginibus sursum conniventibus complicatae, sectioue transversali trigonae, 

 Costa nulla, subtus radicellis villosae et ad margines squamis coloratis transverse oblongis 

 obtusis integerrimis ultra marginem frondis exstantibus, demum pallescentibus paleatae; 

 epidermis ubique papulis elevatis tenerrimis pallidis mamillis pustuliformibus, apice poriferis 

 obtecta; Stratum hypodermicum e cellulis oblongis, erectis viridibus septatis forraatum; reliqua 

 pars frondis inferior e cellulis laxis hyalinis composita, pedunculus e sinu terminali vel 

 inter dichotomiam e substantia frondis inferioris oriendus, basi nudus crassiusculus, car- 

 nosus inferne striatus; receptaculum carnosum apice papulis j^ustulosum, subtus pallidum 

 post egressum capsularum ad pedunculum contractum, filis paucis inconspicuis inclusis; Capsula 

 solitaria per substantiam receptaculi protrusa lateialiter, ad horizontem erumpens fusca, 

 sporis tuberculosis fibrisque repleta. 



Madeira Pico de Baicellos (Johnson) with Lunularia vulgaris. 



Fronds about half an inch long, nearly a line wide; the upper surface of a pale 

 glaucous green, from the translucency of the pustulous epidermis showing the green Stratum 

 beneath it; on each side they are bordered with projecting blackish purple scales, which 

 appear to become afterwards by age almost white. The peduncle is about half an inch 

 long, of a pale brownish colour; it enters the receptacle by a small hole and is affixed to 

 its internal substance near the upper surface. The receptacle appears to be at first nearly 

 globose, but afterwards, by the pushing out of the capsules, the base becomes contracted 

 and tapering to the peduncle ; its substance is soft, and after having been dried it is almost 

 impossible to get a complete idea of its proper form. The capsule appears to force its way 

 through the sides of the receptacle in a horizontal or slightly ascending direction, leaving 

 the orifice entire at its edge without any trace of there having been any suture by which 

 it had opened. No male organs or scyphi have been seen. This curious species differs 

 from the Lmiularia in its peduncle being naked at its base, and from the Jecorariae in its 

 capsules bursting out on the sides of the involucre, which is not radiate, but entire and 

 contracted at its base. 



Auf Madeira ist Exormotheca pustulosa, soviel mir bekannt, sonst nur noch von B,. 

 Fritze im Januar 1880 gesammelt worden, und zwar an mehreren Orten. Der grossen 

 Freundlichkeit Fritze's, der mir seine eigenen Exemplare, der Elfving's und Kihlman's, 

 die mir die Materialien aus der Lind berg 'sehen, jetzt im Museum zu Helsingfors verwahrten 

 Sammlung zur Untersuchung übersandten, verdanke ich die Kenntniss dieser Aufsammlun- 

 gen, deren eine als Fundortsangabe jjRiheiro Sta Luzia«, die andere »ad niuros in pago 

 Gonzalvez et alibi in ditione Funchalensi« trägt. Letzteren Orts wächst sie zwischen Laub- 

 moosen, ersteren ist sie mit Targionia, Fossomhronia caespitiformis und einer Riccia vergesell- 

 schaftet. Auch auf Teneriffa kommt unser Pflänzchen vor. Genau mit denen des Herb.
