Filaments usually very long with basal heterocyte, swollen at the base, then gradually tapering towards the end, without terminal hair, often with false branching, single or double. Sheath 0.5–1.5 µm thick, unstructured, colorless. Trichomes notably constricted at cross-walls, 7–9 µ m wide at the base and 3.0– 4.3 µm wide at well-developed ends. Cells olive green, brown to violet, cylindrical or barrel shaped, shorter or longer than wide, 3–8 µm long, basal:apical ratio 1.8–2. Terminal cell longer than wide, cylindrical or bluntly conical. Heterocytes basal or intercalary, green to yellowish, hemispherical or cylindrical, rarely conical, 4–7 µm wide, 4–8 µm long. Reproduction by hormogonia with almost spherical cells. No akinetes were observed.</p><p>Type species: Calochaete cimrmanii Hauer, Bohunická &amp; Mühlsteinová.</p><p>Etymology:—From the Greek Kalos (beatutiful) and chaete (long hair), refers to one of the morphological features.</p></div>	https://treatment.plazi.org/id/1F7B4A69FFF7FF9151FBFEA5F799D264	Public Domain	No known copyright restrictions apply.

M. Bohunická and J. Mareš, 6 March 2010 (holotype: CBFS! A–015). Type strain: CCALA 1012 .</p><p>Habitat: —Surface soil in “páramo” (tropical high montane vegetation).</p><p>Etymology:—The species is named after the mythical Czech scientist, dramatist, poet, and writer Jára Cimrman.</p><p>Observations:—The life cycle contains several morphologically distinct stages (Fig. 1). One was described above, i.e long, gradually tapering, heteropolar filaments (Figs 1A, B, P). The second consists of hormogonia composed of short, isodiametric, barrel-shaped to spherical cells resembling in morphology Nostoc Vaucher ex Bornet et Flahault (1888: 181) types lacking the sheath (Fig. 1E). Some cells within the hormogonia grow in size and change their shape to spherical (Figs 1D, O). Cells may sometimes divide in more than one plane (Figs 1L, M, O), but never form a true branch. A new filament then germinates from the hormogonia (Fig. 1C). The first cell of the filament becomes a heterocyte. The hormogonia with large spherical cells (e.g. Fig. 1D) occur in young cultures only.</p><p>Our strain differs from the morphologically similar genus Calothrix Agardh ex Bornet et Flahault (1886: 345) by the absence of a terminal hair and frequent false single or double branching (Figs 1G, H, N). As notable from Fig. 2, the 16S rRNA sequence of Calochaete cimrmanii is very distant from members of Rivulariaceae and is more related to Microchaetaceae . The most similar are sequences of Tolypothix strains UAM 332, 334, 337 and PCC 7504, but the degree of tapering is significantly lower in these strains. The low degree of tapering itself is one of the key diacritical features of the genus Tolypothrix Kützing ex Bornet et Flahault (1887: 118), which is accepted in both the botanical (Komárek &amp; Anagnostidis 1989) and bacteriological (Castenholz 2001) literatures. From the above mentioned Tolypothrix strains, Calochaete cimrmanii differs also by living in a significantly different –non-aquatic, high mountain– habitat.</p><p>Comparison of the secondary structures of 16S-23S ITS is of taxonomic importance according to Johansen et al. (2011). To illustrate specificity and the rate of relatedness of the different morphologically similar taxa included in our study, we provide the two most conserved ITS domains, the D1-D1’ and Box-B helices for Calochaete cimrmanii, Tolypothrix sp. PCC 7504 from cluster “B”, Spirirestis rafaelensis Flechtner et Johansen in Flechtner et al. (2002: 6) WJT-71-NPBG6 from cluster “A”, and Calothrix sp. PCC 7507 from a cluster phylogenetically distant from Calochaete (Fig. 3). It can be clearly seen that Calochaete cimrmanii and Tolypothrix PCC 7504 are significantly similar in both structures, especially in the basal parts and the bottom halves of the loops (Figs 3A, B, E, F). Concurrently, there are obvious differences in the top portions of the loops, supporting our decision to separate Calochaete from the traditional genus Tolypothix. The similarity of the secondary structures decreases when comparing Calochaete with Spirirestis as a representative of cluster “A” and the most phylogenetically but supposedly morphologically related Calothrix .</p></div>	https://treatment.plazi.org/id/1F7B4A69FFF7FF9651FBFC4DF738D0A9	Public Domain	No known copyright restrictions apply.
