The flowers are typically 5-merous and the ovaries are mostly 5-locular but a few flowers on the specimens available for study are 4-merous and at least a couple of ovaries are 4-locular in 4-merous flowers. The significance of this variation is difficult to gauge in view of the limited number of flowers and fruits on specimens studied. The specimen label on one collection ( +Maas et al. 5593 +) describes the leaves as green adaxially and wine-colored abaxially. We were unable to determine the consistency of this color difference on opposing leaf surfaces because all of the collections that were available for study turned dark upon drying. + + + +Miconia angustidentata + +does not key satisfactorily to any of the species of + +Clidemia +, +Ossaea +, + +or + +Miconia + +in the most recent accounts of +Melastomataceae +for the Guianas ( + +Wurdack +et al. +1993 + +).

Cell 2 (above the basal cell), measuring 25–65 × 13–15 μm, thinner than the basal cell 1. Horseshoe-shaped trichospores measuring 11.5–16.5 (arch length) × 1.8–3.4 μm (diam), with very short collar and a single appendage measuring 13–16 μm long ( +Figs 6–8 +, +11 +). Fertile branches with up to 20 generative cells, variable in length, 8–25(–40) × 3.5–4.5 μm ( +Figs 6–7 +, +11 +). Elongate or clavate propagules 40–65 × 11.5–13 μm originated from the basal cell and other cells near it ( +Figs 9–11 +).

The species described here resembles most + +G. microsporus + +, but can be differentiated by the larger trichospores in + +G. colombiensis + +(10–12 μm length in + +G. microsporus + +from +France +, according to +Gauthier 1960 +; 6–7.5 μm length in specimens from +Italy +, although probably immature, according to + +Valle +et al. +(2013) + +. Also, fertile branches in + +G. colombiensis + +are highly prolific, producing more generative cells than described in + +G. microsporus +. + +Up to 5 generative cells per fertile branch were reported in specimens of + +G. microsporus + +from +Italy +( + +Valle +et al. +2013 + +); up to +4 in +specimens from +France +( +Gauthier 1960 +, +Lichtwardt 1983 +).

Gauthier ex Manier + +( +Léger & Gauthier 1937 +, +Manier 1962 +, +Valle 2007 +). The propagules are produced from a stout basal cell, and detach to generate new thalli within the same host. In + +G. colombiensis + +, we have observed short rhizoid-like branches arising from the basal cell ( +Figs 3–5 +) and directed towards the hindgut lining, a feature not described in + +G. microsporus + +.

The Asian species + +G. indicus + +was described from +India +( +Misra & Tiwari 2008 +) and reported from Southern +China +( +Strongman & Xu 2006 +), with the key character being the numerous trichospores arranged on fertile branches and the presence of many appendages in the trichospores ( +Strongman & Xu 2006 +), while only one appendage is present in + +G. microsporus + +, + +G. viviparus + +and + +G. colombiensis +. + + + + + \ No newline at end of file diff --git a/data/03/E4/2C/03E42C2F9A728C26FF02E93CFB556F26.xml b/data/03/E4/2C/03E42C2F9A728C26FF02E93CFB556F26.xml new file mode 100644 index 00000000000..b19fa2376bf --- /dev/null +++ b/data/03/E4/2C/03E42C2F9A728C26FF02E93CFB556F26.xml @@ -0,0 +1,291 @@ + + + +First record of trichomycetes associated with aquatic insects from Colombian Moorland and Andean forests + + + +Author + +Barón, Daniel E. + + + +Author + +Valle, Laia Guàrdia + +text + + +Phytotaxa + + +2018 + +2018-07-18 + + +361 + + +1 + + +1 +24 + + + + +http://dx.doi.org/10.11646/phytotaxa.361.1.1 + +journal article +10.11646/phytotaxa.361.1.1 +1179-3163 + + + + + + +Paramoebidium santanderensis +D.E.

However, in + +Paramoebidium santanderensis + +, the papilla should rather be called spore mother-cell, since it is the persistent cystospore which originated the thallus after germination. This phenomena is common in Eccrinales (the spore mother-cell being the sporangiospore), but not in +Amoebidiales +( +Lichtwardt 1986 +). + +P +. +santanderensis + +has a discoid holdfast slightly narrower than the corresponding thallus, while being drastically tapered in + +Paramoebidium ecdyonuridae +(Valle 2014) + +.

Akinetes rarely in basal parts, however this has been reported in a few species. Cell division occurs perpendicularly to the long axis of trichomes. Trichomes dissociate at heterocytes and separately develop into new trichomes.

Striae number 11–15/10 μm and Puncta number 27–33/10 μm ( +Figs 13–16 +). The raphe is undulate ( +Fig. 13 +) and proximal ends are deflected in the same direction ( +Fig. 15 +). A round stigma opening is present in the central area ( +Figs 13, 15 +). External distal ends are deflected in the same direction and extend onto the valve mantle ( +Figs 14, 16 +). At the footpole the distal raphe end bisects apical pore field with porelli clearly separated from the areolae ( +Fig. 16 +). The apical pore fields are located entirely on the valve mantle. Internally, the valve has a conspicuous central nodule that bears a slit-like stigmal opening and proximal raphe ends deflected to one side and recurved ( +Figs 17, 19 +). Distal raphe ends terminate as distinct helictoglossae ( +Figs 18, 20 +).
