Laccaria macrocystidiata, a marasmioid species, originally described as Laccaria affinis f. macrocystidiata from Central Italy, was synonymised with the North American taxon Laccaria laccata var. pallidifolia, but only on a morphological basis. In this paper, the independent position of L. macrocystidiata from L. laccata var. pallidifolia and other...

... holotype consists of a single basidiome in a bad state of conservation (Fig. 2). There are few gills generally without their edge portions or in a bad state of preservation, so cheilocystidia were not found in the examined parts of the lamellae. Spores don't show spines (they are most likely collapsed), but cystidia-like elements up to 40 μm long were found on the stipe surface, and their shape is in accordance ...

... Some of these species lack comprehensive information, while others are not formally described. Despite historical considerations that led to the morphological synonymy of several taxa, phylogenetic relationships among different taxa remain unresolved (Dovana et al. 2021). ...
The genus Laccaria (Hydnangiaceae, Agaricales) is an important ectomycorrhizal symbiont of a broad range of host plants. Laccaria guizhouensis was collected from a subtropical mixed forest dominated by Fagaceae in Southwest China and described based on morphological characteristics and molecular data. Laccaria guizhouensis is characterised by its medium-sized basidiocarps and strong striate or sulcatus, flesh-coloured to brown pileus, flesh-coloured to brown lamellae, 2-to 4-spored basidia, globose to obellipsoid, hyaline, moderately echinulate basidiospores, and 1-1.5 μm-long echinulate. Phylogenetic analyses based on ITS sequences (HMAS352265 and HMAS352266) indicated that L. guizhouensis represented a new species separated from all other Laccaria species.
... The macroscopic characters which may suggest the preliminary identification of L. macrocystidiata are relatively robust basidiomata, notably squamulose pilei and concolorous or even darker than the pilei, fibrillose stipe. Microscopically, the combination of predominantly globose basidiospores, 4-spored basidia and long cheilocystidia set this species apart (Migliozzi & Lavorato 1988;Pázmány 1994;Contu 2003;Dovana et al. 2021). ...
... Described as a form of L. affinis (Singer) Bon (Migliozzi & Lavorato 1988), the independent status of L. macrocystidiata was recently affirmed with phylogenetic evidence by Dovana et al. (2021), also confirming that it is a widespread, but previously unrecognized species. On the Balkan Peninsula it is so far only known from Greece (Dovana et al. 2021). ...
