NOTES

Colonies of S. moelleri in culture closely resemble colonies on natural substrates. Conspicuous conical pegs are formed throughout the culture. Some of these bear a palisade of the conidiogenous apparatus and, thus, can truly be considered as synnemata. Many other of these structures apparently never bear conidia. We call these 'sterile synnemata', but, in fact, are uncertain of their status. Perithecia develop beneath one or more synnemata--fertile, sterile, or both--and the overlying synnema or synnemata adhere to the stromatal wall. Mature stromata come to bear one or more conical spines. As the spines age, they become brittle and tend to break off. Stromata then appear to bear flattened excrescences. The developmental pattern somewhat resembles that of Entoleuca mammata (Wahlenberg) J. D. Rogers & Y.-M. Ju in that stromata of that species are likewise initiated beneath specialized synnematal structures (Rogers & Ju, 1996). That species, however, develops within the bark of dicotyledonous plants and synnemata have a bark-rupturing function.
