Ombrophila janthina 170424 647 ?? on Erica arborea from Madeira
Miguel Ángel Ribes, 01-08-2024 20:25
Miguel Ãngel RibesGood afternoon

This Ombrophila was growing in a very humid place on Erica arborea on the island of Madeira.


The asci are octosporic, with all the spores of similar size, weakly euamyloid and with croziers.


Cylindrical paraphyses with large VBs.


Medullary excipulum strongly gelatinous, with very fine hyphae and presence of crystals. Ectal excipulum with textura prismatica.


Spores ellipsoidal with 2 guttules, (5) 5.6 - 6.4 (6.9) × (3.1) 3.3 - 3.6 (4) µm; Q = (1.4) 1.6 - 1.9 (2.1) ; N = 88; Me = 6 × 3.4 µm ; Qe = 1.7


With Baral's keys I arrived at O. janthina by spore size, but my specimens do not have a stem.


Thanks in advance for your help.

Hi Miguel Angel

no, this is not O. janthina s. auct., which is on conifers and never has such two prominent LBs in the spores.

This belongs in a group of specimens on different angiosperms, the folder of which is currently "janthina - margarita angiosp 4.5-7.5 x 2.5-3.5 bigutt".

Available ITS sequences show that O. janthina s. auct. groups with O. pura whereas yours is in close relationship with "Neobulgaria" premnophila and "N." koningiana.

It would surely be interesting to know if yours has the same ITS as those finds from Europe.

Both premnophila and koningiana have larger spores as far as we know, about 8-11 x 3.5-4.5.

If you tell me the collection date I would properly name your pics in my folder.

Hi Zotto

I see in your folder that you have several similar collections.

This collection is from 04/17/2024, MAR 170424 647, on very wet Erica arborea wood practically submerged in a stream, in Ribeira do Seixal, Porto Moniz, Madeira, Portugal, at 570 m a.s.l.

Yes, I will surely be able to sequence the sample.

Thnk you.

Miguel Angel Ribes.
