Hemitrichia calyculata


Esporangios amarillo-dorados de 1 a 4.5 milimetros de altura, en conjuntos dispersos.
Peridio amarillo claro, hialino y brillante, completo en estado joven y como restos en forma de un calículo (copa) en la base del esporoforo cuando adulto (Fig. 1 y 5).
Pie color café-rojizo a café obscuro mas o menos grande, cilindrico y delgado.
Capilicio amarillo-brillante, reticulado y espiralado de derecha a izquierda.
Esporas amarillo claro al microscopio de campo claro, globosas, equinuladas, de 6 a 8 micras de diámetro (Fig.6).
Plasmodio amarillo y en forma de abanico reticulado.
Sobre madera húmeda y en descomposición, común.

The mustard-yellow fruitbodies of Hemitrichia calyculata are only a few millimetres tall. As the sporangia mature, the outer wall (= peridium) breaks away and the internal mass (capillitium and spores) flounces out like cotton candy, and forms a top-shaped head. The head sits in a shallow cup (=calyculus) that is a persistent remnant of the peridium. The support stalk is short and blackish. This species is very common throughout our region and has a global distribution. The sporangia are produced on logs or stumps in hundreds. When very young, they are a brilliant vermillion to cinnabar colour and are easily spotted. Hemitrichia clavata is very similar but the basal cup (calyculus ) is much deeper and the fruitbodies are thinner and club-shaped to pear-shaped rather than top-shaped.
Spore Dispersal In Trichiales

In all species of Trichia and Hemitrichia the threads of the capillitium are marked with spiral thickenings along their length. As with Arcyria, changes in relative humidity cause moisture to be taken up or lost by the threads and this results in changes in tension along the length of the threads. Adjustments to these tensions causes the threads to wriggle and eject the spores for dispersal by the wind.

I found this info HERE.

Bonjour Felipe & Cristina,
J'apprend beaucoup grâce à vos clichés. Je n'ai jamais remarqué ces organismes dans la nature, j'espère y prêter désormais attention. Les détails, les couleurs et la lumière de vos clichés sont superbes, et l'assemblage très pédagogique.
Bravo et merci pour ce partage.

Hello Felipe and Cristina,
Another very attractive and interesting presentation! All excellent sharp photos and very nice colours. Very nice light too.
TFS and best wishes, Ulla

Very good colaj, the pictures are great and you arranged them very good.

bonsoir a vous deux
je tiens a vous féliciter pour cette composition et présentation, les couleurs sont supers et comme dit HERV2 vous nous apprenez des choses interressantes
félicitations, amitiès

Excelente composición la de estos hongos!
Quedo realmente asombrado de su estructura y agradecido por el trabajo de fotografiarlo y ampliarlos para poder ser observados, lo cual debido a su pequeño tamaño probablemente pasaría desapercibido para mi en caso de verlos.
La calidad de las 3 fotos tomadas con equipos distintos es muy buena.
Verdaderamente que no me queda otra sino felicitaros por tan extraordinaria y didáctica presentación de este tipo de fungi.
Enhorabuena y gracias por publicarla.
Un gran saludo,

Hello Felipe and Cristina!
This is another example how to do a very good presentation. Different points of view show here many interesting details. Moreover, the picture can be characterized by very good DOF with nice colours, details about nature habitat ;> and of course thanks to BG we can see how "huge" are the specimens.
I also like the professional note - as always very interesting and informative.
TFS and... I am waiting for more! ;)
