Dear friends,

I need an advice again.
This Geopora grew on a ground in a wet forest (Picea abies, Betula pendula, Alnus glutinosa, Salix), Czech republic, 320 m asl. Fruitbodies cup-shaped, irregular, 12.5 - 18 mm, hymenium smooth, light greyish, outside short brown hairs.

Spores smooth, ellipsoid, 23 - 25,5 x 12,5 - 13 micrometers, with guttules, asci not bluish in Melzer´s reagent, cylindric, containing 8 spores, 192 - 230 x 16 - 20 micrometer. Paraphyses hyaline, 2 - 5 micrometers broad, septate. Hairs with obtuse apex.

I tried to use the key in Nordic Macromycetes, but I found epigeous fruitbodies, so I wasn´t able to aswer the question about the shape of hypogeous fruitbodies. I excluded G. cooperi (hypogeous), G. arenicola and pellita (1 large guttule, pellita - colour), G. foliacea and sumneriana (2 - 7 cm) and nicaeensis (flesh thick), so tenuis and cervina remained (they should be to 1 cm, but I still think it´s the best possibility).
However, Medardi writes about cervina, that it has got 1 large guttule... in AscoFrance database there´s a photo of cervina having two guttules.
The spores size presented in literature I have fits both on cervina and tenuis.
