PLATE XXII 



Patellinia 



Fig. 113.— p. fragariae S. and P.: single strand, with characteristic 

 branching, from sporogenous area. 



Fig. 114. — Compound meristogenously developed sporodochiimi produced 

 from a number of hyphae, as fig. 113. 



Fig. 115. — Simple meristogenous development with branches arising from 

 a few cells. 



Fig. 1x6. — ^Later stage in simple meristogenous development. 



Fig. 117. — Simple, meristogenously developed, mature sporodochium. 



Fig. 118. — Pestalozzia from quince: sporodochium of compound meristo- 

 genous development ; spore bearing area develops from cuplike top. 



Fig. 119. — ^Another view of sporodochium similar to fig. 118. 



Volutella 



Fig. 120. — V. friicti S. and H.: very early stage in simple meristogenous 

 origin of a sporodochium ; few cells branch to form base. 



Fig. 121. — Slightly later stage. 



Fig. 122. — Medium stage. 



Fig. 123. — Fully developed base or subicle. 



Fig. 124. — Same as fig. 120: smaller hypha. 



Fig. 125. — Later stage than fig. 124. 



Fig. 126. — V. circinans Stevens and True: simple meristogenous origin 

 of subicle in which a cell swells and branches by budding. 



Fig. 127. — Hypha and branches: one branch has developed into a seta. 



Fig. 128. — Beginning of symphogenous development of a subicle. 



Fig. 129. — Later stage. 



Fig. 130. — Many branches interweaving to form a subicle. 



Fig. 131. — Complex symphogenously developed subicle. 



Epicoccum 



Fig. 132. — Epicoccum, species indet.: compound meristogenous develop- 

 ment of simple sporodochium with young spores. 



Meliolai?) 



Fig. 133. — Pycnidium with M.(?) camelliae: 4-cell stage developed from 

 single cell within a hyphal branch. 



Fig. 134. — Many-celled stage apparently developed from end cell of 

 hj^ha. 



Fig. 135. — Mature pycnidium developed from single cell within hypha. 



Fig. 136. — Same as fig. 135. 



Fig. 137. — Slightly different pycnidium from figs. 133, 135.
