Reticularia jurana Meyl. (1908: 297)

Material studied:— NETHERLANDS. Doorwerth, beech branch fallen, 13 Feb 1960, N.E. Nannenga-Bremekamp, box B.M. 4079 [BM001247526], + one slide, s.n. [BM001247536]. IRELAND. W. Galmay, Co. Galway, 5 Sept 1905, C. Torrend, B.M. 2822 [BM001247526] .

The specimen B.M. 4079 was collected and determined by Nannenga-Bremekamp as Reticularia jurana as noted on the herbarium label. However, specimen B.M. 2822, originally determined as R. lycoperdon was corrected by Nannnenga-Bremekamp in 1965 to R. jurana, as noted on the revision label.

Reticularia jurana is characterised by an extensive pseudocapillitium varying from a network of thin filaments with irregular membranous expansions at the junctions to wider filaments with perforated plates. Although the original diagnosis describes the spores as 5–6, rarely 7 µm in diam., the specimens studied by us are somewhat larger (7.5 µm in diam.), in agreement with the observations of Kowalski (1975). Additional data on its outer morphology and microscopic traits were added by Nannenga-Bremekamp (1958).
