170 MORPHOLOGY AND TAXONOMY [Bot. Absts., Vol. IV,. 



the type of a new genus, Hysteropezizella, closely related to Hysteropeziza and with it form- 

 ing a group between the Pyrenopezizaceae and the Mollisiaceae. Here the ascomata are 

 developed below the epidermis. Slegia feneslrata (Roberge) Rehm is made the type of a 

 new genus, Hysterostegiella, of the Hysteropezizaceae, differing from Hysteropezizella in 

 that the ascomata are buried deeply in the host tissue. In Hysterostegiella is also included 

 Stictis valvala Montagne. Throughout the entire paper frequent expression is given to the 

 conviction that in the Hypodermineae, Euphacideae, Pseudophacideae, Stictidieae, Pseudo- 

 pezizeae, Pyrenopezizeae and similar groups the classification will be placed on a sound basis 

 only by giving attention to the position of the ascomata in the host tissue. Naevia minutula 

 (Sacc. & Malbr.) Rehm, iV. exiqua Mout. &Sacc, Trochila Epilobii Karsten, and Peziza Tri- 

 polii Berk. & Br. are transferred to the genus Phacidium. A detailed discussion of the synon- 

 omy of Podophacidium lerrestre Niessl is given. Podophacidium Niessl (syn. Melachroia 

 Boudier) is referred to the Tryblidiaceae. Sphaeronema Spinella Kalchbrenner is transferred 

 to Cytonaema and discussed as the imperfect stage of Tympanis saligna Tode. The genus 

 Cytonaema is removed from the Cytosporeae since its spores are not allantoid and is placed 

 near Chondropodiella. The ascigerous stage of Gelatinosporium pinaslri (Mougeot) v. H. is 

 found to be a new species of Scleroderris and is named S. pinastri v. H. Unguicularia raripila 

 v. H. n.sp. is described. It was collected on dead stems of Lavalera thuringiaca in Austria. 

 From a study of Habrostictis rubra Fckl. (syn. Peziza lasia B. Br.) the conclusion is reached 

 that the genera Habrostictis and Ocellaria are closely related. The genus Cheilodonta 

 Boudier is retained for Peziza carpoboloides Crouan. Pyrcnopeziza Agrostemmatis Fckl., re- 

 garded by Rehm as a doubtful species of Niptera and known hitherto only from the original 

 description, is rediscovered on dead leaves of Agrostemma Githago together with the imperfect 

 stage, Gloeosporium Delaslrei Lacroix, on the stems. Examination of this material shows it 

 to be in reality a species of Fabraea and the name F. Agrostemmatis (Fckl.) v. H. is proposed. 

 Fabrca implexa Bres. & Carestia on Lychnis seems identical. The genus Diplosporonema is 

 tentatively advanced for Gloeosporium Delaslrei Lacroix which is shown not to be a Gloeo- 

 sporium. Peziza sphaeroides var. Lychnidis Desmaz. is found to be the same as Pirottaea 

 veneta Sacc. & Speg. The latter name takes precedence since the name applied by Desma- 

 zieres is a nomen nudum. Examination of the original material of Asteroma impressum Fckl. 

 leads to doubt concerning the validity of this species. Peziza pulveracea Alb. & Schw. is 

 transferred to Dasyscypha and the synonomy is discussed. Peziza echinophila Bulliard, 

 varously classified elsewhere, is here transferred to Rutstroemia. Lachnea (Cheilymenia) 

 furcijera v. H. n. sp. is described. The validity of Aposphaeriopsis fusco-atra Diedicke is 

 questioned, and its identity with certain other described species is suggested. Nitschkea 

 Flagcoletiana Sacc. is shown to be the same as Microlhyrnim epimyces Sacc, its identity with 

 Dothidea episphaeria Peck is suspected, and its removal to the genus Loranthomyces v. H. is rec- 

 ommended. Melanospora similis v. H. n. sp. is described from branches of Cornus sanguinea. 

 It resembles greatly M. theleboloides (Fckl.) Wint. A short discussion is given of Amphi- 

 sphaeria sapinea Karsten (syn. A. dolioloides Rehm). Sphacria mulabilis Pers. is transferred 

 to Enchnosphaeria and is described in detail under the name E. mutabilis (Pers.) v. H. The 

 genus and species Trichocollonema Acrotheca v. H. previously described are here shown to 

 be invalid and are withdrawn. The species described is probably Zignoella macrospora Sacc. 

 Aposphaeriella gregaria Diedicke is shown to be the imperfect stage of Zignoella (Zignoina) 

 pygmaea (Karst.) Sacc. The ascigerous stage of Pestalozzia truncata Leveille is probably 

 Ceratostoma Vitis Fuckel. This conclusion and other similar ones recorded here are based 

 on the examination of material, not on the results of cultures. Appended to the paper is a 

 complete alphabetical list of all the fungi mentioned. — H. M. Fitzpatrick.

 126: 353-399. Fig. 1. 1917. — A new genus, Discosphaerina v. H., regarded as closely related 

 to Guignardia, is founded on a hitherto undescribed species occurring on the leaves of Solidago 

 virgaurea. The species, D. discophora v. H., differs from speces of Guignardia in lacking a 

 definite ostiolum, and in the peculiar structure of the pcrithecial wall. Mycosphaerella tar-
