MISCELLANEOUS. 

 Capnodium, novum Fungorum genus. Auctore C. Montagne, D.M. 



Peridium carnosum, polymorphum, lageniforme, clavatum aut 

 ceranoideum, e duplici strato formatum, exterior! scilicet colorato 

 celluloso, cellulis subirregularibus penta-hexagonis, parallelogranimis 

 (in ostiolo) linearibusque, interiori mucilagineo hyalino fere anhisto, 

 apice irregulariter rumpens, interdum ore fimbriatum. Nucleus ge- 

 latinosus. Sporidia subsena, oblonga, transversim triseptata tandem 

 septis longitudinalibus subeuntibus cellulosa, fuscescentia, ascis late 

 obovoideis vel clavatis, mox difiluenti-resorptis inclusae. 



Thallus superficialis, libere evolutus, nigrescens e floccis brevibus 

 contortis ramosis, moniliformibus aut cylindricis articulatis fuscis 

 dense intricatis compositus. — In Australia, America boreali, Gallia 

 australi et media (ad Versalias) fructiferum inventum. — Locus in 

 systemate prope Anteiinariam. Aflinitates. Habitus Antennaria, at 

 Scoria, Fr. magis affine, cum et in hac nuperrime ascos inveni. Kinc 

 inter GUotrichum et Scoriani nulla adest analogia; similitudinem 

 quamdam, saltem ab aspectus judicio, cum Synalissa habet. Aste- 

 rina et Meliola, qua; Capnodio magis affines, in serie diversa, diffe- 

 runt, prima autem floccis seu fibrillis folio matricive applicatis nee 

 liberis, nee erectis, ultima vei'o fibris setisve rigidis simplicibus lon- 

 gissimis, quibus horrent perithecia, quas perperam pro ostiolis aliqui 

 habuerunt, utraque tandem ascis oligospermis, ut formam perithe- 

 ciorum globosam prteteream. Quoad coUum peridii elongatum, fili- 

 aut corniforme, interdum ore fimbriatum, ut et morphosim sporidio- 

 rum hoc nostrum genus a Melanospora, Corda, baud multum distare 

 videtur, 



Typus generis Capnodil, Fumago Citri, Turpin, Mem. de Nosol. 

 Veget. in Mem. Ac. Sc. de Paris, sav.etr. torn. vi. p. 240 cum icone, 

 sed fructif. non intellecta nee visa. Ascos observavi in specie affini 

 (C. salicinum) ad f)lia Salicum e sect. Cinerella, in Helvetia (d. Rof- 

 favier) necnon circa Parisios (cl. Durieu) lecta. 



PODISOMA FUSCUM. 



There is a small group of Fungi, consisting of the two genera 

 Podisoma and Gymnosporangium, and occurring only on diff^erent 

 species of Juniper, which, in outward aspect, resemble exactly the 

 gelatinous masses of certain TreraeUxR, though in point of fact nearly
