MISCELLANEOUS FUNGI IMPERFECTI 831 



Geotrichum Boyolcpoffi Basgal, Contr. Estiido Blastomicoses Pulmonares 

 48, 1931. 



Isolated from the sputum of a patient in a iiospital at Tomsk, Siberia, by 

 Bogolepov. Further case history and pathogenicity unknown to me. 



Hyphae repent, conidiophores erect, fasciculate, much branched, septate 

 at the base, 40-50/a tall, 2-3/x in diameter at the base, tapering to 0.5/a at the 

 tip ; conidia in heads 7-18ja in diameter ; conidia elongate ellipsoid, 3.5-6.5 x 

 1.1-1.2/A when first cut oft', expanding to 5-7 x 2-2.5/a when fully mature. In 

 young cultures single conidia may be cut off on the repent hyphae. 



Culture white, developing on carrot or nutritive gelatin either at 20° or 

 35° C. When growth is vigorous, the surface is covered with pointed coremia, 

 1-3 mm. long. 



This organism is somewhat problematical as it has not been reported 

 since its original isolation. Since it was studied considerably later in France, 

 it is possible that we have here a contaminant, or occasional organism from the 

 air, accidentally in the sputum. It is also possible that this and the following 

 organism should be placed in GUocladium on account of the branched conidio- 

 phores. 



Cephalosporium Serrae Maffei, Atti 1st. Bot. R. Univ. Pavia IV, 1: 183- 

 198, 9 figs., 1930. 



Cephalosporium sp. Serra, L 'Ateneo Parmense 1 : 549-580, 8 pis., 1929. 



Found in keratomycosis of the eye. Pathogenic to laboratory animals. 



Hyphae branched, decumbent, sparse, hyaline, slender, very little septate, 

 granulose, 2.5-5/i, ; conidiophores not very long, 2.3-4.6/i at the base tapering to 

 1.5-2^ in diameter at the apex. Conidia in heads 8-20yu, in diameter, quickly sepa- 

 rating, hyaline, 2-10 x 2-4-5/i or 4-7.5 x 2/a depending on age and beginning of 

 germination, ellipsoid, spherical, ovoid, oblong-ovoid or pyriform, sometimes 

 slightly constricted in the middle or septate, granulose ; guttulate ; chlamydo- 

 spores solitary or in chains, at first hyaline, then brown, almost always spheri- 

 cal, 4-7/1,; 11-17/A {sic) with a thick membrane. 



Colony rose color at first, becoming fuscous from the mass of brown 

 chlamydospores ; folded irregularly. Gelatin liquefied after 2 weeks. 



Differs from other pathogenic species by larger and little septate hyphae, 

 conidiophores branched and thick with the heads easily breaking up and by 

 the size, form, and guttulation of the conidia and the brown chlamydospores. 

 The branched conidiophores suggest that this species may belong rather in 

 GUocladium near G. roseum (Link) Bainier. 



OORETHROPSIS 



Corethropsis Corda, Prachtflora Europ. Schimmelbidungen PI. 1, 1839 

 [translated as Flore Illus. Mucedineae d' Europe PI. 1, 1840]. 



The tj^pe species is Corethropsis paradoxa Corda (Fig. 128). 



Hj'phae repent, septate ; conidiophores short, short simple or 2-3-furcate, 

 erect, slightly swollen at the tip, bearing a head of radiating conidia. Conidia 

 with short sterigmata, ellipsoid, hyaline, unicellular.
