ASYMMETRICA-DIVARICATA 269 



of rarely more than three asci. The manner of attachment to the myce- 

 hum has not been estabhshed nor is it clear whether, in time, asci develop 

 more abundantl}^ from hyphae at first showing scattered asci only. In 

 his description of P. javanicum, van Beyma (1929) referred to the presence 

 of a "skein" which we interpret to mean the network of hyphae upon which 

 the abundant asci of that species are borne. The same hyphal network is 

 seen in other species showing the initially firm or sclerotioid type of peri- 

 thecium, but in no species is it more extensive than in P. haarnense. In 

 P. egyptiacum van Beyma such a network is clearly evident, and in amount 

 is somewhat intermediate between P. javanicum and P. haarnense. 



True monoverticillate penicilli are sometimes produced in Penicillium 

 haarnense, but these represent the exception rather than the general rule. 

 The species is accordingly assigned with P. egyptiacum and P. asperum as a 

 constituent member of the Carpenteles series. 



Penicillium {Carpenteles) euglaucum van Beyma (Antonie van Leeuvvenhoek 6: 

 268-270. figs. 3-4. 19.39/40), as represented by the type strain received in December 

 1945 from the Centraalbureau, duplicates the above in all essential characters. This 

 species was based upon a culture isolated by Dr. Marie Ledeboer, Natal, South Africa, 

 from the bark of an acacia tree. It was originally described by van Beyma as char- 

 acterized by small, smooth, globose conidia 2.0 to 2.3 or even 2.7m in diameter, (ap- 

 pearing rough with oil immersion), and ascospores 3.0 to 4.0m by 3.0 to 3.3m, slightly 

 roughened, and showing a definite equatorial band. In our cultures both the conidia 

 and the ascospores of the type, now maintained as XRRL 2087, duplicate those of 

 P. haarnense as described above. Furthermore, the two types are strikingly similar 

 in plate cultures upon many different substrata. It seems unlikely that the culture 

 received as P. (C.) euglaucum is not the strain studied originally by van Beyma, since 

 it agrees with his description in most particulars. We are led to believe that the 

 species should be regarded as synonymous with P. haarnense, and that it differs from 

 the latter only within the limits of normal strain variation.

Colonies on Czapek's solution agar growing fairly rapidly, attaining a 

 diameter of 4.0 to 4.5 cm. in 12 to 14 days at room temperature (fig. 72A), 

 somewhat radially furrowed, comparatively deep, up to 1 mm. or more in 

 central to subcentral areas, with surface loose-textured to floccose, pre- 

 dominantly white to cream colored, broadly zonate in some strains, azon-

 areas in some strains, light b"ue-green near gnaphalium green (Ridgway,

 colony appearance; perithecia abundantly produced in some strains, not 

 in others, when massed appearing granu'ar and tan to avellaneous in color;
