Observations. 
Its extent is very great, ascending from the most simple forms to those which are very compound, but at the 
same time connected with the former by the most strict natural ties. The true place of the genera in the 
system has been a subject of doubt. Many authors have taken them for fungi in the most perfect state. Decan- 
dolle excludes them from fungi, and, with some analogous L,ichens, refers them to a peculiar intermediate 
family. 
They are found in every part of the world in which vegetation exists ; for every perfect plant and all its 
decaying parts nourish Pyrenomycetes. The chief families of trees in the European Flora upon which they 
flourish are Conifers, Amentaceae, Kosaceee, Ericea?, Rhamnoideas, Acerinse, and Tiliacea;, and of herbs, 
Gramineae, Umbellifers, and LiliaceEe. Many are peculiar to certain species of trees, and others are common 
to many species. For example, on the Betula alba may be found about ten peculiar species, and from forty to 
fifty which are common to it and other trees. Their qualities are unknown. Many species which are included 
by Fries under the name of Ectostroma, are probably not vegetables, and are here omitted.
