 points out various peculiarities in the structures of ascospores of Xylariaceae which sim- 

 plify the classification of these fungi. The following fungi are discussed: Xylaria polymorpha, 

 Xylaria Hypoxylon, Hypoxylon fuscum, Ustulina vulgaris, Xylaria hippotrichoides, Thamno- 

 myces hippotrichoides, Rhizomorpha tuberculosa, Daldinia conccntrica, Poronia punctata, 

 Nummularia discreta, Rosellinia Julii, Anthostoma atropunctatum, Anthostoma targidum, 

 Penzigia compuncta, Wawelia regia. — Fred. C. Werkenthin.

 thyriaceae resembling and mistaken for Discomycetes.] Ber. Deutsch. Bot. Ges. 36: 465-170. 

 1918. — Micropeziza scirpicola Fuckel and Discomycella tjibodensis v.H., formerly considered 

 true Discomycetes, belong to the Microthyriaceae. Belonidium aurantiacum Rehm forms the 

 characteristic shield of the Microthyriaceae, but develops also a parenchymatous excipulum 

 thereby constituting a transition form to the few Discomycetes which are related to theHelo- 

 tiaceae. The new genera Calycellina and Cenangina, together with the three forms above 

 mentioned, would constitute a natural group the first members of which must still be consid- 

 ered as belonging to the Microthyriaceae, while the last members are typical Discomycetes. 

 Micropeziza scirpicola Fuckel and Belonidium aurantiacum Rehm are closely related and differ 

 only in the development of the excipulum. Both are to be included in the new genus Niess- 

 lella of the Microthyriaceae. — Ernst Artschwager . 



1177. vox Hohnel, F. tiber den Zusammenhang von Meliola mit den Microthyriaceen. 

 [Relation of Meliola to the Microthyriaceae.] Ber. Deutsch. Bot. Ges. 36: 471-473. 1918. — 

 The perithecia of Meliola develop exactly as the perithecia of the Microthyriaceae, namely 

 on the lower side of the subicular hyphae; there is no difference then, between a thyriotheeium 

 and a perithecium in Meliola. However, between the forms Amazonia Psychotriae and Meli- 

 ola corallina there is a big gap. The former is a typical Microthyrium, while the latter is 

 a true Meliola. An intermediate form is found in Dimerosporium Litscae P. Henn. which was 

 described by Hennings as belonging to the Perisporiaceae. Sydow later put it in the new genus 

 Armatella. However, Armatella does not develop a hypostroma as claimed by Theissen and 

 Sydow, and the fruit body does not resemble Polystomella but the Meliola species which lack 

 the spines of the fruit body. It is easy to understand why Dimerosporium Litscae was 

 considered as belonging to the Microthyriaceae, since the description was based on unripe 

 material and the juvenile stage of a Meliola is hardly distinguishable from members of the 

 Microthyriaceae. — Ernst Artschwager.
