to 1900 as Gloeosporium) a saprophyte on eapsules of Calalpa bignonioides. (4) P. poli/H]><>ra 

 Bub. et Syd. parasitic on leaves of Acer daaycarpum. (5) Leptosphaeria crepini (Westd.) do 

 Not. on sporophylls of Lycopodium annolinum turning them black. (G) Pyrenochaeta clith- 

 ridis n. sp. described from an old fruit body of Clithris quercina, Phoma salsolcn n. sp. from 

 Salsola kali and Aecidium sp.? from Rhamnus fallax. (7) New species of saprophytic fungi 

 described and the host range for old ones extended. [Through abst. by Matouschek in 

 Zeitschr. Pflanzenkr. 29: 252-253. 1919 (1920).]— D. Reddick. 



19G3. Murrill, W. A. A correction. Mycologia 12: 108-109. 1920.— An error in citation 

 is noted in 25 species of polypores which are found to have been transferred to the genus 

 Poria by Cooke two years in advance of Saccardo's transfers. — H. R. Rosen. 



1964. Murrill, W. A. Daedalea extensa rediscovered. Mycologia 12: 110-111. 1920. — 

 Specimens collected in Indiana are referred to D. extensa; Peck's original description of this 

 species is given. — H. R. Rosen. 



1965. Murrill, W. A. Polyporus excurrens Berk. & Curt. Mycologia 12: 107-108. 

 1920. — This species is considered as synonymous with Trametes rigida Berk. & Mont., Poly- 

 stictus extensus Cooke, P. rigens Sacc. & Cub., Coriolopsis rigida (Berk. & Mont.) Murr. 

 Since American specimens referred to Trametes serpens are considered distinct from the 

 European material T. subserpens is suggested as a new name for American material. — H. R. 

 Rosen. 



1966. Murrill, W. A. Light-colored resupinate polypores— I. Mycologia 12: 77-92. 

 1920. — Twenty-seven species of Poria are presented including P. incerla (Pers.) comb. nov. 

 and the following new species. P. umbrinescens, P. lacticolor, P. niveicolor, P. cr emei color , 

 P. adpressa, P. tenuipora, P. Earlei, P. corioliformis, P. regularis, P. polyporicola, P. cin- 

 ereicolor, P. subavellanea, P. snbcorticola, P. Amesii, P. subcollapsa, P. rnonticola, P. lac- 

 lerata, P. rimosa, and P. heteromorpha. "The descriptions included are mainly from dried 

 specimens. Before the hundreds of such specimens in the herbarium here can be intelli- 

 gently discussed, referred to, or classified, they must be named and more complete descriptions 

 can be prepared later." — H. R. Rosen. 



1967. Murrill, W. A. Illustrations of fungi— XXXII, Mycologia 12: 59-61. PI. 2 (col- 

 ored). 1920. — Boletus luteus, Tylopilus alboater (Boletus nigrellus), and Armillaria nardos- 

 mia are described and illustrated. — H. R. Rosen. 



1968. Northrup, Zae. A new method of preparing cellulose for cellulose agar. [Abstract.) 

 Absts. Bact. 3 : 7. 1919. — "The method is as follows: Melt over a free flame at a low heat 200 

 grams of ferric chlorid in a porcelain casserole. Add to this completely melted salt a known 

 weight of absorbent cotton, a little at a time (stir with a glass rod), as much as the melted 

 salt will dissolve without making the mixture too thick to be handled readily. When com- 

 pletely dissolved, pour into a large volume of distilled water; a heavy precipitate of finely 

 divided hydrocellulose occurs. Filter by using a Buchner or similar funnel plus suction and 

 wash the precipitate thoroughly on the filter with distilled water. After the thorough wash- 

 ing with distilled water, if any trace of iron chlorid remains, it may be considered as negligible 

 as it is harmless, and may be actually beneficial to the medium. Weigh the moist precipitate 

 to determine the proportion necessary to use per unit weight of original cellulose in making 

 cellulose agar. The weight of hydrocellulose corresponding to 2 grams of absorbent cotton 

 has been found sufficient in Omeliansky's and other cellulose agar media. Pure absorbent 

 cotton dissolves much more satisfactorily than filter paper and gives a more finely divided 

 precipitate, consequently this is the form now employed as a standard in our laboratory."

1969. Northrup, Zae. Agar-liquefying bac+eiia. [Abstract.] Absts. Bact. 3: 7. 1919. 

 — Found in anaerobic culture from soil. Pure cultures are to be isolated and studied. — D. 

 Reddick.
