ASYMMETRICA-VELUTINA 411 



but described and figured as clearly belonging in this series, and showing delicately 

 roughened walls; conidia ovate to subglobose, 2.5 to 3.5m in long axis. Thorn's notes 

 (1930) made on a culture received from Baarn as Zaleski's type describe colonies of 

 the general type reported by Zaleski, and likewise describe conidiophore walls as 

 pitted or granular; conidia were observed by him to be elliptical and to range from 

 3.0 to 3.5m in long axis. A culture received from Baarn under this name in 1946 pro- 

 duces colonies indistinguishable from P. stolonijerum. The species obviously repre- 

 sents some member of the P. brevi-compactum series, and basing our opinion upon 

 original descriptions rather than cultures now in our possession, P. bialowiezense is 

 regarded as probably approximating P. hrevi-compactum Dierckx, 



Penicillium hagemi Zaleski (in Bui. Acad. Polonaise Sci.: Math. et. Nat. Ser. B, 

 pp. 448-450; Taf. 39. 1927. Thom, The Penicillia, pp. 298-299. 1930) was described 

 with colonies growing restrictedly, radiately wrinkled and centers elevated with 

 conidiophores from 300 to 400m by 3.5 to 4.0m, either smooth or rough walled; the peni- 

 cillus was reported and figured as showing 2 or 3 comparatively long branches with 

 walls occasionally roughened; metulae and sterigmata fairly compactly arranged; 

 conidia ovate to subglobose, 2.5 to 3.5m in diameter. Thorn's notes (1930) made from 

 the type strain confirmed the above in general but failed to mention the character of 

 the conidiophore walls. The species is believed to be inseparable from P. hrevi-com- 

 pactum as described above. A culture received from George Smith under this name 

 as a culture from Baarn (and probably type) shows penicilli with cellular elements 

 and conidia large but otherwise representative of the series. Two cultures received 

 from Baarn as their isolates of P. hagemi present well enough the characteristics at- 

 tributed to the species by Zaleski, but fail to show sufficient differences to warrant 

 recognition as a separate species in the P. hrevi-compactum series. 



Penicillium patris-mei Zaleski (in Bui. Acad. Polonaise Sci.: Math, et Nat. Ser. B, 

 pp. 49&-498, Taf. 58. 1927; Thom, The Penicillia, p. 303. 1930) was described as 

 producing strongly wrinkled, irregular colonies with conidiophores extremely vari- 

 able in length and 2.0 to 2.5m in diameter, commonly flexuous with walls smooth and 

 bearing compact asymmetric penicilli. Thorn's notes (1930) made on a strain from 

 Baarn as Zaleski's type described buckled and radiately wrinkled colonies with yel- 

 lowish green conidial areas and reverse in yellowish to grayish brown; penicilli were 

 reported to be of the P. hrevi-compactum type with metulae compacted at the base, 

 bearing crowded sterigmata and conidia more or less elliptical, about 3.5m in long axis. 

 Cultures received under this name from George Smith and Baarn, and believed to 

 have stemmed from Zaleski's type, show conidiophores sometimes roughened, and 

 clearly belong with P. hrevi-compactum Dierckx as described above. 



Penicillium szaferi Zaleski (in Bui. Acad. Polonaise Sci.: Math, et Nat. Ser. B, pp. 

 447-448, Taf. 38. 1927; Thom, The Penicillia, pp. 299-300. 1930) was described as 

 producing restricted, radiately wrinkled colonies with surface hirsute, pale green to 

 dark yellow-green in color; conidiophores 300 to 500m by 4.0 to 4.5m, with walls slightly 

 asperulate; penicilli were comparatively large with metulae and sterigmata arranged 

 compactly. Thom's notes (1930) made from the type indicated colonies of the same 

 general pattern, but reported conidiophores smooth-walled. No authentic cultures 

 have been available for the present study but the species is regarded as probably in- 

 separable from P. hrevi-compactum Dierckx, as presented above.
