Blue with long black hairs

Miguel Ángel Ribes, 18-05-2011 19:55

Good evening

I have this small (0.4-0.9 mm) "asco" with blue hymenium and long black hairs (Me = 310.1 x 7.2 µm), in laurel forest, La Gomera.

1000x Ciliated spores with water (15.1) 17.2 - 22.9 (26.5) x (1.6) 2.0 - 2.7 (3.0) µm; Q = (5.7) 7.0 - 10.0 (12.9) ; N = 5; Me = 19.8 x 2.4 µm ; Qe = 8.4

Spores with IKI

Miguel Ángel Ribes, 18-05-2011 20:06

Re:Blue with long black hairs

The spores source is uncertain, because I have not see any asci. I have see this image with the spores sourcing from hymeniun, but it is imposible to contain 8 spores in this structure, I think.

Miguel Ángel Ribes, 18-05-2011 20:07

Re:Blue with long black hairs

This is the nearest "asci" image I have see, with IKI.

Re:Blue with long black hairs

Bonsoir,

c'est un champignon imparfait, qui s'appelle Pseudolachnea hispidula, si je ne me trombe pas.

amicalement,
Andreas

Re:Blue with long black hairs

Another structure is a lot of "conidios" ¿?, in water, (42.0) 47.0 - 58.4 (66.9) x (1.4) 1.6 - 2.3 (2.5) µm
Q = (21.0) 23.3 - 34.4 (42.6) ; N = 50; Me = 53.0 x 1.9 µm ; Qe = 28.0

Miguel Ángel Ribes, 18-05-2011 20:11

Re:Blue with long black hairs

I think this is the "conidios" source.

Gernot Friebes, 18-05-2011 20:13

Re:Blue with long black hairs

Hi Miguel,

looks like a Pseudolachnea (anamorphic fungus). Nice photos!

Best wishes,

Gernot

Re:Blue with long black hairs

Dear René and Gernot

I have been looking for this three genus, and Pseudolachnea hispidula looks like a good candidate, but I only have a spores picture from Baral's DVD and internet one.

I have see it is published here: Pseudolachnea hispidula (Schrad.) B. Sutton, Mycol. Pap. 141: 167 (1977).
And the original description is here: Peziza hispidula Schrad., J. Bot. (Schrader) 2(1): 64 (1799).
But I have not none.

And, what are that long not ciliated "conidia"?

Thank you very much, very quick and certain response.

Re:Blue with long black hairs

Peut-être un Dinemasporium ?

Miguel Ángel Ribes, 19-05-2011 10:13

Re:Blue with long black hairs

Dear Guy

I only have find this paper about Dinemasporium from China, really similar to Pseudolachnea. With the key I arrive to D. lanatum Nag Raj, T.R.; Castañeda-Ruiz, R.F., 1989, Canadian Journal of Botany 67(8): 2527: http://www.fungaldiversity.org/fdp/sfdp/26-8.pdf.
In this paper is said Dinemasporium, Pseudolachnea and Stauronema are similar genera, but I do not know the separation limit.

I have no more papers related to Pseudolachnea nor Dinemasporium. Any more help, please?

Thank you.

Hola Miguel Angel:
Tengo yo un par de hallazgos en hojas de Phragmites communis y en herbácea indeterminada, de ayer mismo.
A ver si avanzo yo también, con estas.

Hola Miguel Angel:
Tengo un par de hallazgos de Pseudolachnea, uno sobre hojas de Phragmites communis y otra sobre herbácea indeterminada, de ayer mismo.
Espero progresar también con estas dos.......

Re:Blue with long black hairs

Gracias Javier

Si consigues documentación sobre Pseudolachnea y Dinemasporium acuérdate de mi. Supongo que todavía no les has hecho micro, ya me dirás si coincide con lo mio. Tiene toda la pinta.

Un abrazo,
