Pezicula sp?
Miguel Ángel Ribes, 03-03-2011 01:15
Miguel Ãngel RibesBuenas noches
Esta pequeña especie naranja de 1-2 mm crecía sobre madera de planifolio en bosque de laurisilva, subgloboso-urceolado de joven y turbinado con el himenio convexo de adulto, de consistencia firme.
Ascas con croziers, biseriadas, con la base muy estrecha y larga, IKI ¿creo que no azul?, de (149) 159.1 - 203.7 (218.1) x (9.9) 10.7 - 12.3 (14.3) µm; N = 20; Me = 186.5 x 11.5 µm, en agua, a 600x, a partir de material fresco.
Esporas en forma de pipa, muy pocas veces con 1-2 septos y varias gútulas medianas, de (14.1) 14.9 - 18.2 (19) x (4.2) 4.7 - 6 (6.3) µm; Q = (2.5) 2.7 - 3.4 (4) ; N = 36; Me = 16.4 x 5.4 µm ; Qe = 3.1
Paráfisis muy particulares, muy ramificadas, multiseptadas, moniliformes e irregulares en toda su longitud.

Muchas gracias por vuestra ayuda,

Good night
This small orange species 1-2 mm was growing on planifolium wood in laurel forest, subglobose-urceolate when young and turbinate with convex hymenium in adults, flesh firm.
Asci with croziers, biseriate, with very narrow and long base, IKI ¿I think not blue?, (149) 159.1 - 203.7 (218.1) x (9.9) 10.7 - 12.3 (14.3) microns, N = 20, Me = 186.5 x 11.5 microns, in water, 600x, from fresh material.
Pipe-shaped spores, rarely with 1-2 septa and several medium-size guttules, from (14.1) 14.9 - 18.2 (19) x (4.2) 4.7 - 6 (6.3) microns, Q = (2.5) 2.7 - 3.4 (4), N = 36, Me = 16.4 x 5.4 microns, Qe = 3.1
Paraphyses very curios, highly branched, multiseptate, moniliform and irregular along its length.

Thank you very much for your help

Dear Miguel

congratulations! This is

Zugazaea agyrioides Korf, Iturr. & Lizoň, in Iturriaga, Korf & Lizoň, Mycologia 90(4): 697 (1998)

I revised type material, see here.

Could you provide us with a crop of an ascus apex in IKI to better see the reaction?

Dear Zotto

Here is an asci apex collage.

I have been reading the paper of Prof. Korf and your plate and I think the paraphysis in this collection are slightly different, much more moniliform. Is it not important?

In this album you could see all my micro photos, there are many "normal" paraphysis, but also many other moniliform-deformed, at least at the apex.

Re:Pezicula sp?
Dear Miguel

many thanks for these nice photos. About branching of paraphyses I often saw high variation, f.ex..in Orbilia or Vibrissea etc.

I downloaded a lot of your photos, but i regret the micros are in low resolution (700 x 556). If you have higher I would like them at least in double.
