The larch coniferous hair cup ( Lachnellula occidentalis ) is a species of fungus from the Hyaloscyphaceae family .
features
Macroscopic features
The larch-coniferous hair cups form short-stalked chalice-shaped 1–3, in exceptional cases up to 5 mm wide, sociable growing apothecia , which are overgrown with white hairs on the outside and whose fruit disc ( hymenium ) is yolk to orange-yellow.
Microscopic features
The hair is hyaline , thin-walled, fine-grained and with a rounded tip. The ascusporus reacts hemiamyloid, i. H. with Lugol red, with KOH pre-treatment blue. The spores are elliptical-spindle-shaped, are 17–20 × 5–8 μm in size and are septate once when ripe. The paraphyses are thread-like, slightly broadened at the tip (2.5 to 3.5 μm wide) and sometimes branched. Sometimes they also form septate conidia that are filled with orange droplets.
Occurrence and ecology
The larch coniferous wood hair cup occurs exclusively saprobionic on dead branches of larch, more rarely also on other coniferous woods such as spruce or mountain pines from the colline to montane , rarely also subalpine altitude. It's hard from larch Krebsbecherchen to distinguish that the larch cancer causes. It is important to pay particular attention to the presence of cancerous swellings and otherwise to separate these two types mainly on the basis of the different iodine reactions of the asci. The differentiation between the two species is not only difficult with dried herbarium material, since the size of the spores can fluctuate.
It is common in all larch forests in Central Europe. The database of mushrooms Austria lists it as the most common Lachnellula species and has specimens from all federal states except Burgenland and Vienna. It is also given as the most common softwood hair cup for Germany.
