F. THEISSEN : HYPOCRÉACEAE RIOGRANDENSES 



133 



Ad Bambusaceas. 



Exsicc. Rick, F. austro-am. 117. 



Perithecia inveni ovata, 280 = 230 papilla brevíssima; asei 

 55-60=5-5 V 2 pedicello sensim attenuato 15-20 \j. longo. Spo- 

 rae ovoideae, monostichae, raro subconstrictae, cellulis interdum 

 inaequalibus. f 



Neoskofitzia 



45. Neoskofitzia hypomycoides Rick — Annal. myc. 1905 

 P- 239. 



In Polyporo mucido. 



Perithecia globosa, 240-270 \x diam., sordide luteo-brunneola, 

 subiculo albo mucedineo, postea evanido, insidentia, hyphis basali- 

 bus hyalino-flavidis, longe articulatis, ramosis, 3 a cr. 



Asei 55-60 — 3 1 / 2 -4 [J- ; sporae hyalinae, 6 1 / 2 -7 = 3 p. sece- 

 dentes. 



Species ob sporas hyalinas melius Hypocreae adscribenda vide- 

 tur. — Differentia inter Neoskofitziant et Hypocream reponi vix po- 

 test in subiculo, sed aptius in sporis coloratis, sicut genus Dime- 

 rium contraponitur Dimerosporio etc, ; quodsi ob notam stromato- 

 logicam subiculi genus proprium separatur, eodem jure subgenera 

 Hypocreae ordinem reclamant generis. Nimis durum autem vide- 

 tur tam arctam resolvere affinitatem. Rx altera tamen parte diffi- 

 cultas est in determinando gradu coloris, qui sit proprius Neosko- 

 fitziae, cum etiam genuinae species Hypocreae sporas exhibeant co- 

 loratas. Censeo igitur genus Neoskofitzeae ínterim ad Hypocream 

 remittendum esse.
