Rhodotarzetta rosea ?

Another pyrophilous species was collected in the same community after fire.

The specimen also was lost, but it's beautiful cups should be possible to identify, i hope.


Mixed coniferous-aspen after fire forest, West Siberia near Khanty-Mansiysk (61.08148N, 69.48450E).


Spores with two guttules, smooth, 13.9 (13-14.8) x 8.3 (7.6-9.4) (only 6 spores measured, so that real size could be biased).


Nina.

Re : Rhodotarzetta rosea ?
The last species from this after-fire community, probably Tarzetta catinus, with spores 13 x 8 mk on the average (61.08148N, 69.48450E).

Re : Rhodotarzetta rosea ?
About R. rosea, I think you're right, although the size of ascospores shows that specimens are immature. The habitat on burnt place is typical.
About the second species, nothing can be said with a single immature specimen. This is probably a Tarzetta, but impossible to name it.

Re : Rhodotarzetta rosea ?
Hello Nicolas,

thanks for your comments,

Uwe Lindemann also wrote me in personal that most probably R. rosea (but spores are smaller and he asked send him a specimen, i will do it).

Nina.
