I think circinella sp

It looks like Lichtheimia- Absidia sp. for me. You must try growing at 37ºC. Lichtheimia is thermotolerant and has a good growth at this temperature. Good luck!

Hi Aleksandra,

yes, it seems to be a Mucor sp.

However for identification to species, you would need to measure the sporangiosphores, to check which are the most predominant shape of them if they are branched or not. How the colony on MEA looks like. I can not see very well if the columella has apical projections. Are most of  the columellae ovoid to pyriform?

Diana is right, you must see diferent characteristics to species identification. But for me it´s not a Mucor sp. because this picture its showing a distict apophysis and no Mucor species has apophysis.

Thanks for Answers!

I can on weekend measure the sporangiosphores.

I have yet photo.

I don't on MEA cultutre. I may try.

Yes. With more pictures we can recognize better that the fungus actually produces sporangiophores with apophyses, which is an indication that this is related to an species from Absidia sp. Check if the colony characteristics correspond to Absidia glauca. ;)

Best,

Diana

Thanks :)

my suggestion is also to Absidia 

Thanks. Does anyone knows key for Adsidia?

Genus Absidia Tiegh.

The genus Absidia produces a distinctive type of columella which widens gradually at the junction with the stipe, outside the circumference of the sporangium (Fig. 6.4b). In other Zygomycete genera considered here, the junction of stipe andcolumella is abrupt, and the columella is wholly within the sporangial wall. In age, columellae of Absidia frequently collapse inward from the apex to form funnel-shaped structures. Absidia species form rhizoids, irregular root-like outgrowths at the bases of the stipes, but these are less conspicuous and less regular than in Rhizopusspecies. Only one Absidia species, Absidia corymbifera, is at all common in foods. Several recent authors have concluded that Absidia is polyphyletic (evolutionarily diverse) based on molecular studies (e.g. Voigt et al., 1999; O’Donnell et al., 2001; Kwasna et al., 2006) and that A. corymbifera is not closelyrelatedtomostotherspeciesinthegenusand would be better classified in Rhizomucor. However, this name remains in common use.

On CYA, colonies covering the Petri dish, low and sparse, white to pale brown or grey; reverse colourless. On MEA, colonies filling the whole Petri dish with deep floccose mycelium, coloured mid-grey by sporangia; reverse pale. On G25N, colonies 10–30 mm diam, sparse and floccose, coloured as on MEA. No growth at 58C. At 378C, colonies covering the whole Petri dish, similar to those at 258C. Sporangiophoresbornefromaerialhyphae,stipes sometimes irregularly branched; sporangia hyaline, 15–50 mm diam, appearing pyriform due to external conical columellae; columellae pyriform 10–30 mm diam,sometimeswithsmall projectionsontheapices or with collarettes above the base, in age often collapsing inward from the apex to form funnel-shaped structures;sporangiosporeshyaline,broadlyellipsoidal to spheroidal, 3–6 mm long, smooth walled. Distinctive features. See genus description. Physiology. Evans (1971) recorded growth temperatures for Absidia corymbifera as minimum 148C, maximum 508C and optimum near 408C. This species is able to germinate and grow down to 0.88 aw (HockingandMiscamble,1995).Growthinnitrogen (
