ASCOMYCES. 899 
Order IX—GYMNOASCEZ. Sadebeck.* 
Without a receptacle, or an indication of one only in 
the more highly developed genera; asci either single or 
in little tufts, arising from widely creeping hyphe; or 
more or less closely crowded together into hymenia; 
or, lastly, arising from the terminal branches of copiously 
ramifying hyphz in pellets, which are covered with a 
lax mycelial veil. 
Name—yvupvoc, naked, aoxéde, aleather bottle; here 
meaning an ascus. 
Genus I—<Ascomyces. Mont. et Desm., “Ann. Se. Nat.,” 
ser. 3, vol. xi. p. 345 (1849). 
Parasitic on living plants; asci not seated on a proper 
receptacle, but on the cuticle of the host-plant, closely 
pressed together in little tufts or extended layers, arising 
from the mycelium, which ramifies between the epi- 
dermal cells and the cuticle. Their effect is to cause the 
injured parts to change colour, to swell into blisters, and 
become much enlarged. The asci are very small, 
cylindrical, clavate, or subpyriform, and contain 8 (or 
more ?) sporidia. (Plate XII. fig. 79.) 
Name—aoxée, ascus, pine, a fungus; fungi consisting 
of asci only.

* Professor Sadebeck has contributed a revision of this order to Dr. 
Winter's new eilition of Rabenhorst’s “ Cryptogamin-Flora von Deutsch- 
land,” the arrangement of which is followed here as regards the genus 
Ascomyces. ‘The order is not included in the Discomycetes in the work 
quoted.
