2,17 FOLIA CRYPTOGAMICA 218 Sulphur Algae from Hungary By Dr Kaare Münster Ström (Oslo) In the year 1905 the late*) Professor Dr N. Wille visited Hungary for some time. Among the plants he collected were a number of Sulphur Algae, partially from Margit-sziget (Margarethen-insel) near Buda-Pest, and partially from Herkules-fürdó (Herkulesbad) and the Cserna Valley. On the whole there were 28 dried samples which he presented to me for investigation. Concerning the Algal flora of the sulphur springs in Hungary and adjacent countries we know a good deal through papers by Hansgirg, Strzeszewski, Szafer, Vouk and others, and there are also some specimens distributed in exsiccati. Especially are the investigations by Strzeszewski (Beitr. z. Kenntn. d. Schwefelfl. i. d. Umgeb. v. Krakau), Szafer (Z. Kenntn. d. Schw. fl. i. d. Umg. v. Lemberg) and Vouk (Biol. Unters. d. Thermal-quellen v. Zagorje i. Kroatien) extensive and partly carried out according to biological prin-ciples. The 26 sampjes which were at my disposal were thus signed: 1. Sulphur Algae from the sulphur springs in Margit-sziget) Budapest, June 20th 1905. 2—26. Sulphur Algae from the sulphur springs in Herkulesfürdó. June 22nd 1905. From the town proper and up in the Cserna valley. Partially from the water and from stones in hot steam. (Where no locality is mentioned the Algae are from Herkulesfürdó) Class Myxophyceae. Order Hormogoneae. Family Rivulariaceae. Genus Calothrix Ag. 1. Calothrix parietinum (Naeg.) Thur. var. thermalis G. S. W. This characteristic variety, which is described from the hot Icelandic geysirs was present in considerable quantities in a number of samples from Herkulesfürdó. Family Stigonemaceae. Genus Hapalosiphon Naeg. 2. Hapalosiphon laminosas (Cohn.) Hansg. This-widely distributed thermal Alga was remark-*) * 28. X. 1858 (Hobol in Smaalenene) f 4.II. 1924 <T5ien, Oslo). (Eingegangen am 6. XI. 1926) ably scarce, and was only observed from a single collection. Family Oscillatoriaceae. Genus Microcoleus Desm. 3. Microcoleus sociatus W. & G. S. W. This interesting species which was originally described from Africa was occurring in quantities in a single sample. It is previously found to occur in sul-phur springs in Pjatigorsk in Caucasus also. (K. Münster Ström: Fr. w. Algae Cauc. and Turkestan.) Size: lat. trich. 2,5 p long cell. 3 , 5 - 4 p. Genus Phormidium Kuetz. 4. Phormidium laminosum (Ag.) Gom. This Alga, which is perhaps the most general in hof springs throughout the World, was very common, and occurred in as much as 10 collections. S ize : lat. trich. 0,8—1,2 p. Genus Oscillatoria Vauch. 5. Oscillatoria geminata Menegh. var. sul-phur ea. Strzesz. This very characteristic variety occurred in abundance in one sample from Mar-git-sziget. Size: lat. trich. 2, long. cell. 2 ,5—4,2 p. 6. Oscillatoria animalis Ag. This characte-ristic species occurred in three or four samples. 7. Oscillatoria terebriformis Ag. The Alga occurred in abundance in four collections. S ize : lat. trich. 5 ,2—5,3 p. 8. Oscillatoria numidica Gom. Oscillatoria numidica is only reported on a few times, and seems to be a characteristic thermal Alga. It occurred in a single sample. 9. Oscillatoria Okeni Ag. This common ther-mal Alga was present in a single sample only. 10. Oscillatoria formosa Bory. Oscillatoria formosa was observed from a couple of collec-tions. Size: lat. trich. 5 p. 11. Oscillatoria sp. Some undeterminable of Oscillatoria occurred in one or two collections. Order Coccogoneae. Family Chroococcaceae. Genus Chroococcus Naeg. 12. Chroococcus minor (Kuetz.) Naeg. This 2,17 FOLIA CRYPTOGAMICA 218 ubiquitous species occurred in abundance in a single collection. 13. Chroococcus sp. Undeterminable Chroo-coccus species were present in a couple of col-lections. Some of them are doubtless species described as various forms of Aphanotece, but their specific identity could not be ascertained. Genus Gloeocapsa Naeg. 14. Gloeocapsa thermalis Lemm. There may be very great doubt, whether this form should be separated from Gloeocapsa Magma as a species or not. Size: diam. cell. 1,5—2,8/«. [Separatim editum 1927. 25. II.] \
