orifice various more or less exserted.

Division II. Cytisporei. 
Closed, perforated by an orifice. Asci none ; sporidia surrounded by a little bag or thin cellule, deliquescent. 
2427. Sphceronema. Perithecium opening by a pore, enclosing in a very thin bag some mucous sporidia, 
which burst forth and become indurated in a globose form. Naked. 
2428. Septaria. (See Notes.) 
2429. Cytispora. Cellular-many-celled ; cells deformed, membranous, united at ends. Nucleus gelatinous, 
filled with sporules, propelled through the common elongated orifice. 
2430. Phoma. Nucleus grumous, enclosed in a tubercle. Sporidia emitted by a simple orifice without 
regularity. 
Division III. Phacidiacei. 
Perithecium finally bursting, with an open disk. Asci erect, fixed. 
2431. Bothidea. Nucleus inclosing immersed cellules. True perithecium obliterated. Asci erect, remain- 
ing for a long time. 
2432. Rhytisma. Perithecium deformed, bursting into transverse fragments by means of a flexuose crack. 
2433. Phacidiufn. Receptacle O. Perithecia sessile, depressed, bursting from the centre towards the circum- 
ference in several acute segments. Sporuliferous cells elongated, fixed. 
2434. Hysterium. Perithecia mostly oblong, black, corneous, bursting by a longitudinal slit. Sporuliferous 
tubes erect. (Crust none.) 
Division IV. Xylomacci. 
Asci obsolete. Sporidia innate. 
2435. Actinothyrium. Perithecium buckler-like, with radiating fibres covering the fusiform sporidia. 
2436. Leptostroma. Perithecium uniform, without an orifice, but entirely separating and exposing a very 
thin disk. 
2437. Xyloma. Black, corneous. Perithecia single, solitary and minute, or united and confluent, irregu- 
larly dehiscent. 
Observations. 
terrestrial ; the imperfect kinds being inhabitants either of plants or of the dung of animals. Many are 
meteoric, flourishing most in " Jove tonante, densisque cadentibus imbris;" others are ephemeral; some exist 
for a month and more. 
The Phalloideas are generally very fastid, cold, and venomous ; one species is accounted in China a vulnerary, 
and also a food, but of doubtful quality. The old physicians had some peculiar notions about their use in 
arthritis, &c. but they are not worth repeating. The Tuberaces have a peculiar smell, which is often grateful ; 
their taste is irritating ; their qualities esculent, nutritive, and aphrodisiacal. 
Class II. Pyrenomycetes. Tlie affinity of this class is very complex, for which reason there is much 
difference of opinion among authors as to its limits. In fructification it approaches fungi of a higher degree of 
developement ; on one hand resembling the Angiogastres, from which it is readily distinguished by its sepa- 
rate receptacle ; on the other hand, the Cupulati, whose differences depend upon the definition of their 
perithecium. In point of vegetation it descends, first, to Sclerotiaceaj, which are entirely diflTerent, in the 
absence of an uterus and nucleus ; secondly, to Perisporia, which have no distinct perithecium, and no asci ; and 
thirdly, to several genera of Coniomycetes.
