Fries' Nomenclature of Colours in the Agaricini.* — H. J. 

 Wharton enumerates and seeks to elucidate the colour-names used 

 for descriptive purposes by Fries, when treating of the Agaricini in 

 his ' Hymenomycetes Europfei,' as well as most of those used as 

 specific names. Avoiding compounds, nearly 200 names of colours 

 are here collected and discussed. 



Corynelia.f — This genus of fungi, hitherto placed doubtfully 

 among the Pyrenomycetes, has now been determined by G. Winter, 

 from material obtained from Capetown, to be quite a typical repre- 

 sentative of this group. The perithecia are of the ordinary structure 

 of the Sphseriacese ; but the form of the ascospores is very peculiar. 

 They are composed of a roundish central piece, and of four, rarely fi.ve, 

 somewhat conical portions, attached to the central piece by their 

 bases, while their ends stand out. This is the form of the spores in 

 C. tripos ; while in the only other species known, G. uberata, they are 

 of a much more ordinary nearly globular form. 



Cryptica, a New Genus of Tuberaceae.| — Under the name 

 Cryptica lutea^ E. Hesse describes a fungus which he has found 

 abundantly in beech-woods in Germany, and which he regards as the 

 type of a new genus intermediate between Hydnocystis and Genea, 

 and therefore near the boundary line between the Tuberacete and 

 Discomycetes. It is readily distinguished at a glance by the floc- 

 culent nature of the upper yellow half of the pitted fructification 

 (receptacle), and the reddish-brown colour of its lower portion. 



The gleba is fleshy, and is permeated by a number of streaks (or 

 veins) which spring from the inside of the peridium, of a brownish- 

 yellow colour. Between each pair of these yellow veins is a colour- 

 less " vena lymphatica," which puts out asci and paraphyses right 

 and left, reaching to the yellow veins, and in places even to the 

 peridium. The asci are large and of beautiful cylindrical form, from 

 • 03 to • 05 mm. in diameter, variable in length, and especially in 

 that of their contracted lower portion ; they are not unfrequently 

 curved about their middle. They are enveloped by a large niunber 

 of slender paraphyses. The spores are formed eight in an ascus 

 with great uniformity. They are spherical, and when ripe their 

 exospore is covered with blunt warts ; they are about • 02 mm. in 

 diameter. Gryptica is hypogaeic, and is found beneath a covering of 

 beech-leaves along with other fungi of similar habit. 



Parasitic Fungi.! — In connection with a descriptive account of 

 all the fungi parasitic on animals, E. Morini proposes a genealogical 

 tree of the class of Fungi generally, of which the following are the 

 main outlines. Starting from the original group of Protomycetes, 

 consisting of the Schizomycetes and Saccharomycetes, the tree 

 branches into three main arms, viz. I. Entomophthorese, Ustilagineffi, 

 Uredinese, Tremellinete, Hymenomycetes (Hymenolichenes), Gastero-
